Quotes & Sayings About Extinction Of Species

If warming were held to a minimum, the team estimated that between 22 and 31 percent of the species would be "committed to extinction" by 2050. If warming were to reach what was at that point considered a likely maximum - a figure that now looks too low - by the middle of this century, between 38 and 52 percent of the species would be fated to disappear. — Elizabeth Kolbert

No magic bullet, not even the Internet, can save us from population explosion, deforestation, climate disruption, poison by pollution, and wholesale extinction of plant and animal species. We are going to have to want different things, seek different pleasures, pursue different goals than those that have been driving us and our global economy. — Joanna Macy

We torture and kill two billion sentient living beings every week. 10,000 entire species are wiped out every year because of the actions of one, and we are now facing the sixth mass extinction in cosmological history. If any other organism did this, a biologist would consider them a virus. — Philip Wollen

Many scientists would argue that we are now in what is called Extinction, and it's caused by this perfect extinction storm: climate change, habitat loss, pollution, unsustainable exploitation of species and habitat resources, and of course, human population explosion. All of these factors work together and conspire to drive a species to extinction on our planet, every half an hour. — Jeff Corwin

You would be hard pressed, I would submit, to find a better pairing of occurrences to illustrate the divine and felonious nature of the human being - a species of organism that is capable of unravelling the deepest secrets of the heavens while at the same time pounding into extinction, for no purpose at all, a creature that never did us any harm and wasn't even remotely capable of understanding what we were doing to it as — Bill Bryson

In the beginning, there were bacteria ... [A] nearly universal assumption is that all subsequent life descended from the original life form through a continuous chain of ancestor-descendant pairs. This assumption looks good because all living organisms share biochemical traits. It is conceivable, of course, that life originated more than once on the early earth but that all except one life form died out early, leaving a single lineage as the ancestor of life as we know it. If this did happen, it was the first important species extinction. — David M. Raup

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund. — Richard Dawkins

It is a rule in paleontology that ornamentation and complication precede extinction. And our mutation, of which the assembly line, the collective farm, the mechanized army, and the mass production of food are evidences or even symptoms, might well correspond to the thickening armor of the great reptiles - a tendency that can end only in extinction. If this should happen to be true, nothing stemming from thought can interfere with it or bend it. Conscious thought seems to have little effect on the action or direction of our species. — John Steinbeck

There is evidence that we are headed into what would be the planet's sixth mass extinction. It's hard to know for sure if you're in one because a mass extinction is an event where over 75 percent of the species on the planet die out over a - usually about a million-year period. The fastest it might happen is in hundreds of thousands of years. — Annalee Newitz

We are the hands and eyes and ears, the sensitive probing feelers through which the emergent, intelligent universe comes to know its own form and purpose. We bring the thunderbolt of meaning and significance to unconscious matter, blank paper, the night sky. We are already divine magicians, already supergods. Why shouldn't we use all our brilliance to leap in as many single bounds as it takes to a world beyond ours, threatened by overpopulation, mass species extinction, environmental degradation, hunger, and exploitation? Superman and his pals would figure a way out of any stupid cul-de-sac we could find ourselves in - and we made Superman, after all. All it takes is that one magic word. — Grant Morrison

The humanity and the humility, which are very different than the biological species homo sapiens. Humanity versus homo sapiens - very different things. We are biological creatures, we are animals, no doubt, but when you talk about "humando," you're talking about that particular kind of animals who are aware of their impending extinction, who have the capacity to be sensitive to catastrophe and disaster and calamity and profound crisis. — Cornel West

Without death there is little innovation. Extinction - death of a species - is part and parcel of evolutionary change. In the absence of this kind of extinction new developments would not prosper. In our own history, periods when ideas have been perpetuated by dogma, preventing the replacement of old by new ideas, have also been times of stultifying stagnation. The Dark Ages in western society were the most static, least innovative of times. So the fact that trilobites were replaced by batches of successive species through their long history was a testimony to their evolutionary vigour. — Richard Fortey

This is what we can promise the future: a legacy of care. That we will be good stewards and not take too much or give back too little, that we will recognize wild nature for what it is, in all its magnificent and complex history - an unfathomable wealth that should be consciously saved, not ruthlessly spent. Privilege is what we inherit by our status as Homo sapiens living on this planet. This is the privilege of imagination. What we choose to do with our privilege as a species is up to each of us.
Humility is born in wildness. We are not protecting grizzlies from extinction; they are protecting us from the extinction of experience as we engage with a world beyond ourselves. The very presence of a grizzly returns us to an ecology of awe. We tremble at what appears to be a dream yet stands before us on two legs and roars. — Terry Tempest Williams

A billion homo sapiens are added every 11 years to the planet. The hypertrophy of a single species pushes other life-forms out of bed and into extinction. The decline of biological diversity is real and severe. The alarming loss of soil fertility, forest cover, and coral reef viability and the release of fossilized CO2 that nature put away 300 million years ago in its march toward greater diversity - all these "losses" and many others are the result of one life-form annihilating other life-forms in its immoral confusion of "dominion" with "domination." — Leonard Sweet

This fundamental subject of Natural Selection will be treated at some length in the fourth chapter; and we shall then see how Natural Selection almost inevitably causes much Extinction of the less improved forms of life and induces what I have called Divergence of Character. In the next chapter I shall discuss the complex and little known laws of variation and of correlation of growth. In the four succeeding chapters, the most apparent and gravest difficulties on the theory will be given: namely, first, the difficulties of transitions, or in understanding how a simple being or a simple organ can be changed and perfected into a highly developed being or elaborately constructed organ; secondly the subject of Instinct, or the mental powers of animals, thirdly, Hybridism, or the infertility of species and the fertility of varieties when intercrossed; and fourthly, the imperfection of the Geological Record. In — Charles Darwin

Perhaps the most crucial stage is that of 'intraspecies chaos.' This is the proving ground, the awkward adolescence when a species either learns to come together on a global scale, or dissolves into squabbling factions doomed to extinction, whether through war or ecological disasters too great to tackle divided. — Becky Chambers

We poetically construct our identity as human beings, together with our values, largely through reciprocal relationships with animals. They provide us with essential points of reference, as well as illustrations of the qualities that we may choose to emulate or avoid in ourselves. Any major change in our relationships with animals, individual or collective, reverberates profoundly in our character as human beings, in ways that go far beyond immediately pragmatic concerns. When a species becomes extinct, something perishes in the human soul as well. — Boria Sax

Few problems are less recognized, but more important than, the accelerating disappearance of the earth's biological resources. In pushing other species to extinction, humanity is busy sawing off the limb on which it is perched. — Paul R. Ehrlich

Field biologists studying large and charismatic animals wanted to know if their own species had genetic problems. I listened carefully to stories of koalas in Australia, giant pandas in China, black-footed ferrets in the Midwest, elephants, rhinos, and leopards in Africa, and orangutans in Asia--all threatened or endangered species attended by packs of worried field biologists. If cheetahs paid a price for their brush with extinction, did these species suffer the same? — Stephen J. O'Brien

Human use of fossil fuels is altering the chemistry of the atmosphere; oceans are polluted and depleted of fish; 80 per cent of Earth's forests are heavily impacted or gone yet their destruction continues. An estimated 50,000 species are driven to extinction each year. We dump millions of tonnes of chemicals, most untested for their biological effects, and many highly toxic, into air, water and soil. We have created an ecological holocaust. Our very health and survival are at stake, yet we act as if we have plenty of time to respond. — David Suzuki

background extinction." In ordinary times - times here understood to mean whole geologic epochs - extinction takes place only very rarely, more rarely even than speciation, and it occurs at what's known as the background extinction rate. This rate varies from one group of organisms to another; often it's expressed in terms of extinctions per million species-years. — Elizabeth Kolbert

The human race has the capacity to render itself extinct unless alternatives are found to the patterns of intraspecific warfare that have dominated civilized history. Ours has long been a predatory species. Living, for humans, depends upon the ability to kill as clearly as it does for lions or wolves. But lions and wolves, like almost all predatory species, normally limit their killing to prey animals, and they are equipped with elaborate ritual precautions to prevent the destruction of their own kind. Humans appear to be unique among predators in their enthusiasm to destroy members of their own species. Perhaps this unusual behavior can be attributed to some genetic deficiency which may lead humans ultimately to join the rest of nature's failures in the biological graveyard of extinction. Or perhaps our willingness to kill ourselves, like so many of our other problems, is something we have devised by misusing our enlarged brains. — Joseph W. Meeker

One animal or plant species may become extinct every hour. All species are doomed to extinction, but man through worldwide development/killing animals for food/profit/using toxic chemicals such as pesticides/industrial wastes, will accelerate the extinction of plants/animals and the result will be a more hostile environment for man. — Erik P. Eckholm

Is this how it is for a species that senses it is going extinct? Is there a feeling of loneliness, or unease, each morning, upon awakening? — Rick Bass

We are killing off species at the rate of about one per day. It is estimated that humans are driving species to extinction at least a thousand times faster than the otherwise natural rate. — Bill Nye

The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals. — Thomas Huxley

There is a beginning and end to all life - and to all human endeavors. Species evolve and die off. Empires rise, then break apart. Businesses grow, then fold. There are no exceptions. I'm OK with all that. Yet it pains me to bear witness to the sixth great extinction, where we humans are directly responsible for the extirpation of so many wonderful creatures and invaluable indigenous cultures. It saddens me to observe the plight of our own species; we appear to be incapable of solving our problems. — Yvon Chouinard

The point I want to make about methanogens is that they were the losers in the race through a bottleneck, yet nonetheless survived in niche environments. Similarly, on a larger scale, it is rare for the loser to disappear completely, or for the latecomers never to gain at least a precarious foothold. The fact that flight had already evolved among birds did not preclude its later evolution in bats, which became the most numerous mammalian species. The evolution of plants did not lead to the disappearance of algae, or indeed the evolution of vascular plants to the disappearance of mosses. — Nick Lane

A species may eat a particular bacterium, phytoplankton, smaller fish, or plant in an area. Lacking a predator, these species/populations will overgrow and alter the area's biology, overwhelming and driving to extinction dozens or hundreds or thousands of other local species. — Thom Hartmann

There can be no doubt that the existing Fauna and Flora is but the last term of a long series of equally numerous contemporary species, which have succeeded one another, by the slow and gradual substitution of species for species, in the vast interval of time which has elapsed between the deposition of the earliest fossiliferous strata and the present day. — Thomas Henry Huxley

Long after the traces of the human animal have disappeared, many of the species it is bent on destroying will still be around, along with others that have yet to spring up.

The Earth will forget mankind. The play of life will go on. — John N. Gray

In this twenty-first century, there's no one like Sharona Muir who can write, in bright accurate language, animals real or imaginary in an updated bestiary that riffs on evolution, extinction, and what it means to be human among other species. We need this view, and you'll be right there with her on every page of Invisible Beasts. — John Felstiner

I just wonder what it would be like to be reincarnated in an animal whose species had been so reduced in numbers than it was in danger of extinction. What would be its feelings toward the human species whose population explosion had denied it somewhere to exist. I must confess that I am tempted to ask for reincarnation as a particularly deadly virus. — Prince Philip

Humans, after all, weren't actively hostile toward most of the species we'd made extinct over the millennia of our ascendance; they simply weren't part of our design. The same could turn out to be true of superintelligent machines, which would stand in a similar kind of relationship to us as we ourselves did to the animals we bred for food, or the ones who fared little better for all that they had no direct dealings with us at all. — Mark O'Connell

There are six billion egos living on this planet. Can you not see why the world is in such a sorry state? Can you not see why we are destroying Heaven on Earth for our own short-term gain? Can you not see why the tiger and the gorilla are facing extinction, along with countless other species? Can you not see why there is so much injustice, abuse, greed, cruelty, and inequality upon this planet? We get along with those who share the same set of illusions. It is called collusion. They are our friends. We declare war on those who dare to believe in another set of illusions. They are our enemies. Religion, and particularly religious fundamentalism, is the most obvious and dangerous example. Nationalism is another. "Me! Me! Me!" "Mine! Mine! Mine!" "I'm right. I'm right. I'm right." "How can I use this or make use of this?" "What's in it for me?" You — Mary Bruggeman

we, as a species, now stand at a crossroads. We can face the possibility of our own extinction and work to avert it, or we can follow the more traditional path of earth's organisms and fall blindly over the edge. If there's one trait that characterizes human beings, it's the will to survive. This, I believe, will motivate us to work with the natural world rather than oppose it, which is all we need to do to give the children of earth - of all species - the opportunity to thrive. — Alexandra Morton

Don't believe what you hear about those penguins. A species of lazy waddlers. Their extinction is immanent. — Benson Bruno

Why are so many religious people arguing about the origin of the species but so few concerned about the extinction of the species? — Brian D. McLaren

His interest, after all, was not in the origin of species but in their demise. — Elizabeth Kolbert

We'll lose more species of plants and animals between 2000 and 2065 than we've lost in the last 65 million years. If we don't find answers to these problems, we're gonna be victims of this extinction event that we're at fault for. — Paul Watson

Without world unification the species would destroy itself by the enlarged powers that had come to it. This, said the men of science, is no theory, no political alternative; it is a statement of fact. Men had to pool their political, economic and educational lives. There was no other way for them but a series of degenerative phases leading very plainly to extinction. They could not revert now. They had to go on - up or down. They had gone too far with civilisation and in societies, to sink back into a merely "animal" life again. The hold of the primates on life had always been a precarious one. Except where they were under human protection all the other great apes were extinct. Now plainly man had to go on to a larger life, a planetary existence, or perish in his turn. — H.G.Wells

Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us. — Mark Kurlansky

They may not become extinct immediately, but being pushed out of decaying or destroyed habitats eventually takes its toll. The concept is known as extinction debt, the delay between the stress on species and the final dwindling of the last survivors until the organisms disappear and are never seen again. — Craig Childs

The damage that climate change is causing and that will get worse if we fail to act goes beyond the hundreds of thousands of lives, homes and businesses lost, ecosystems destroyed, species driven to extinction, infrastructure smashed and people inconvenienced. — David Suzuki

The extinction of Homo Sapiens would mean survival for millions, if not billions, of Earth-dwelling species. Phasing out the human race will solve every problem on Earth - social and environmental. — Ingrid Newkirk

And we really should be considering the moral implications of what we're doing. What kind of a species are we that we treat the rest of life so cheaply? There are those who think that's the destiny of Earth: We arrived, we're humanizing the Earth, and it will be the destiny of Earth for us to wipe humans out and most of the rest of biodiversity. But I think the great majority of thoughtful people consider that a morally wrong position to take, and a very dangerous one. — Edward O. Wilson

Mark Spitz had met plenty of the divine-retribution folks over the months. This was their moment; they were umbrella salesmen standing outside a subway entrance in a downpour. The human race deserved the plague, we brought it on ourselves for poisoning the planet, for the Death of God, the calculated brutalities of the global economic system, for driving primordial species to extinction: the entire collapse of values as evidenced by everything from nuclear fission to reality television to alternate side of the street parking. Mark Spitz could only endure these harangues for a minute or two before he split. It was boring.The plague was the plague. You were wearing galoshes, or you weren't. — Colson Whitehead

We human beings are not only the beneficiaries but also the stewards of other creatures. Thanks to our bodies, God has joined us so closely to the world around us that we can feel the desertification of the soil almost as a physical ailment, and the extinction of a species as a painful disfigurement. Let us not leave in our wake a swatch of destruction and death which will affect our own lives and those of future generations. — Pope Francis

The diversity of life on Earth, generally, is astonishing. But despite those large numbers, it's also important to recognize that every species, one way or another, is vulnerable to extinction. And in our time on Earth our impact on the diversity of life has been profound. — Sylvia Earle

From a shamanic perspective, the psychic blockade that prevents otherwise intelligent adults from considering the future of our world - our obvious lack of future, if we continue on our present path - reveals an occult dimension. It is like a programming error written into the software designed for the modern mind, which has endless energy to spend on the trivial and treacly, sports statistic or shoe sale, but no time to spare for the torments of the Third World, for the mass extinction of species to perpetuate a way of life without a future, for the imminent exhaustion of fossil fuel reserves, or for the fine print of the Patriot Act. This psychic blockade is reinforced by a vast propaganda machine spewing out crude as well as sophisticated distractions, encouraging individuals to see themselves as alienated spectators of their culture, rather than active participants in a planetary ecology. — Daniel Pinchbeck

Shelters, conservationists, those concerned about unnecessary cruelty toward the animals we eat, and people working against species extinction fight to preserve the true riches of our planet, our real inheritance. These are big, critical goals. — April Gornik

One saw a bird dying, shot by a man. It was flying with rhythmic beat and beautifully, with such freedom and lack of fear. And the gun shattered it; it fell to the earth and all the life had gone out of it. A dog fetched it, and the man collected other dead birds. He was chattering with his friend and seemed so utterly indifferent. All that he was concerned with was bringing down so many birds, and it was over as far as he was concerned. They are killing all over the world. Those marvellous, great animals of the sea, the whales, are killed by the million, and the tiger and so many other animals are now becoming endangered species. Man is the only animal that is to be dreaded. — Jiddu Krishnamurti

A sign in the Hall of Biodiversity offers a quote from the Stanford ecologist Paul Ehrlich: IN PUSHING OTHER SPECIES TO EXTINCTION, HUMANITY IS BUSY SAWING OFF THE LIMB ON WHICH IT PERCHES. — Elizabeth Kolbert

During your lifetime, the people of our culture are going to figure out how to live sustainably on this planet
or they're not. Either way, it's certainly going to be extraordinary. If they figure out how to live sustainably here, then hum anity will be able to see something it can't see right now: a future that extends into the indefinite future. If they don't figure this out, then I'm afraid the human race is going to take its place among the species that we're driving into extinction here every day
as many as 200
every day — Daniel Quinn

There are species that retain their characteristics even in conditions that are relatively different from their natural ones; other species in similar circumstances instead become extinct; otherwise what takes place is racial mixing with other elements in which no assimilation or real evolution occurs. The result of this interbreeding closely resembles Mendel's laws concerning heredity: once it disappears in the phenotype, the primitive element survives in the form of a separated, latent heredity that is capable of cropping up in sporadic apparitions, even though it is always endowed with a character of heterogeneity in regard to the superior type. — Julius Evola

It may sound peculiar coming from an old punk rocker, but I strongly believe that governmental policies are the only viable way to administer our long-term success as a species. I guess you could say that my attitude of 'fuck the government' is still intact. But it's more a criticism of lousy government than a statement of nihilism. The truth is, when it comes to environmental protection, the government is the best way to enact a new social awareness by establishing laws by which industries have to abide. — Greg Graffin

No influence of ours can save your species from destruction. Nothing could save it but a profound change in your own nature; and that cannot be. Wandering among you, we move always with fore-knowledge of the doom which your own imperfection imposes on you. Even if we could, we would not change it; for it is a theme required in the strange music of the spheres. — Olaf Stapledon

Every day on this planet some species that doesn't draw the attention of humans goes extinct. — Liu Cixin

By 2050, at bio-extinction's current rate, between 25 per cent and 50 per cent of all species will have disappeared or be too few in numbers to survive. There'll be a few over-visited parks, the coral reefs will be beaten up, grasslands overgrazed. Vast areas of the tropics that have lost their forests will have the same damn weeds, bushes and scrawny eucalyptus trees so that you don't know if you're in Africa or the Americas. — Stuart L. Pimm

The First Wave Extinction, which accompanied the spread of the foragers, was followed by the Second Wave Extinction, which accompanied the spread of the farmers, and gives us an important perspective on the Third Wave Extinction, which industrial activity is causing today. Don't believe tree-huggers who claim that our ancestors lived in harmony with nature. Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving the most plant and animal species — Yuval Noah Harari

'Extinction' issue. Save the species for whom??? Humans' convenience, of course! Individuals of the species are snatched from their homes/family/habitat/held in captivity/forced to mate at great physical/ spiritual pain. When the right numbers are reached, their holocaust starts all over again! Another merry-go-round/ bu$ine$$ a$ u$ual!!! Protectionists/welfarists find it a profitable issue: no controversy/ easy donations! I'd rather see an entire species extinct than in the hands of the humans! — Adela Popescu

And there was shame in being human: the shame of knowing that twenty of the roughly thirty-five classified species of sea horse worldwide are threatened with extinction because they are killed "unintentionally" in seafood production. — Jonathan Safran Foer

It may be underfunded and at times mismanaged, but the [Endangered Species] Act is an unprecedented attempt to delegate human-caused extinction to the chapters of history we would rather not revisit: the Slave Trade, the Indian Removal Policy, the subjection of women, child labor, segregation. The Endangered Species Act is a zero-tolerance law: no new extinctions. It keeps eyes on the ground with legal backing-the gun may be in the holster most of the time, but its available if necessary to keep species from disappearing. I discovered in my travels that a law protecting all animals and plants, all of nature, might be as revolutionary-and as American-as the Declaration of Independence. — Joe Roman

I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families. — Asa Gray

It is a fact that the ecological devastation of the planet can be traced to the consumption of meat and dairy, which contributes to water, soil, and air pollution as well as global warming and the mass extinction of many species of plant and animal forms. — Sharon Gannon

Besides, morality is not about whether the human race survives, but about what kind of survival it gets. We marry; guppies don't. We don't eat our young; they do. Yet neither species is in danger of extinction. — J. Budziszewski

Humans are only one species of millions. To kill millions of species for the benefit of one is insane, just as killing millions of people for the benefit of one person would be insane. And since unimpeded ecological collapse would kill off humans anyway, those species will ultimately have died for nothing, and the planet will take millions of years to recover. Rapid collapse is ultimately good for humans because at least some people survive. And remember, the people who need the system to come down the most are the rural poor in the majority of the world: the faster the actionists can bring down industrial civilization, the better the prospects for those people and their landbases. Regardless, without immediate action, everyone dies. — Aric McBay

Our problem with limited resources is not primarily overpopulation; it is greed. Our problem with pollution is not the invention of fluorocarbons or mass transport; it is irresponsibility. The loss of an acre of forest every second, the mass slaughter of elephants for their ivory, the extinction of entire species of plants, insects and animals all over the world is not something that "just happens" because there are more of us human beings. It happens because the race of ruling beings put in charge has almost wholly lost its sense of stewardship. We have turned away from God. — Winkie Pratney

If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment. — E. O. Wilson

Science cannot tell you whether abortion is wrong, but it can point out that the (embryological) continuum that seamlessly joins a non-sentient foetus to a sentient adult is analogous to the (evolutionary) continuum that joins humans to other species. If the embryological continuum appears to be more seamless, this is only because the evolutionary continuum is divided by the accident of extinction. Fundamental principles of ethics should not depend on the accidental contingencies of extinction.* To repeat, science cannot tell you whether abortion is murder, but it can warn you that you may be being inconsistent if you think abortion is murder but killing chimpanzees is not. You cannot have it both ways. — Richard Dawkins

A high jeopardy of extinction comes with territory. Islands are where species go to die. — David Quammen

We're handing them [young people & future generations] a climate system which is potentially out of their control. We're in an emergency: you can see what's on the horizon over the next few decades with the effects it will have on ecosystems, sea level and species extinction — James Hansen

In the 24 hours since this time yesterday, over 200,000 acres of rainforest have been destroyed in our world. Fully 13 million tons of toxic chemicals have been released into our environment. Over 45,000 people have died from starvation, 38,000 of them children. And more than 130 plant and animal species have been driven to extinction by the actions of humans. And all this just since yesterday. — Thom Hartmann

If there is danger in the human trajectory, it is not so much in the survival of our own species as in the fulfillment of the ultimate irony of organic evolution: that in the instant of achieving self-understanding through the mind of man, life has doomed its most beautiful creations. — Edward O. Wilson

If in your lifetime you watch a species go extinct, or plummet almost to the point of extinction, that is a sign that something really serious is going on. — Elizabeth Kolbert

He sat there thinking of Man's capacity for the wiping out of species
sometimes in hate or fear, at other times for the simple love of gain. — Clifford D. Simak

Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us. — Al Gore

An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction. — Rusty Schweickart

You may have heard that America doesn't have enough scientists and is in danger of "falling behind" (whatever that means) because of it. Tell this to an academic scientist and watch her laugh. For the last thirty years, the amount of the U.S. annual budget that goes to non-defense related research has been frozen. From a purely budgetary perspective, we don't have too few scientists, we've got far too many, and we keep graduating more each year. America may say that it values science, but it sure as hell doesn't want to pay for it. Within environmental science in particular, we see the crippling effects that come from having been resource-hobbled for decades: degrading farmland, species extinction, progressive deforestation... The list goes on and on. — Hope Jahren

There's a voice that says: "So what?"
It's not my voice, it's probably not yours, but it makes itself heard in the arenas of public opinion, querulous and smug and fortified by just a little knowledge, which as always is a dangerous thing. "So what if a bunch of species go extinct?" It says. "Extinction is a natural process. Darwin himself said so, didn't he? Extinction is the complement of evolution, making room for new species to evolve. There have always been extinctions. So why worry about these extinctions currently being caused by humanity?" And there has always been a pilot light burning in your furnace. So why worry when your house is on fire? — David Quammen

The number of people displaced by dams is estimated at between 40 million and 80 million, most of them in China and India. The costs of dams were on average 50% above their original estimate. Some designed to reduce flooding made it worse, and there were many unexpected environmental disadvantages, including the extinction of fish and bird species. Half the world's wetlands had been lost because of dams. — Paul Brown

During the past thirteen billion years humanity has become an enormous presence on earth, as if it were an envelope surrounding the planet. All other species are now influenced by humanity, and humanity is literally determining the genome of the earth community. We affect how the rest of the planet survives - or not. The one notion that not only envelops but suffocates the planet is that of industrial growth, which inherently fosters the perspective of the earth as a resource rather than as a relationship we must cultivate. Humanity is now being challenged to replace the resource concept with a deeply emotional experience of the earth as a being with which we are related. — Carolyn Baker

What is your personal carrying capacity for grief, rage, despair? We are living in a period of mass extinction. The numbers stand at 200 species a day. That's 73,000 a year. This culture is oblivious to their passing, feels entitled to their every last niche, and there is no roll call on the nightly news. — Lierre Keith

One of the laws of paleontology is that an animal which must protect itself with thick armour is degenerate. It is usually a sign that the species is on the road to extinction. — John Steinbeck

Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time. — P.D. James

We discover too late that we have turned a blind eye to the extinction of a species that is essential to the balance of life in a particular context. Or we discover too late that the importation of a foreign life-form, animal or vegetable, has upset local ecosystems, damaging soil or neighbouring life-forms. We discover that we have come near the end of supplies-of fossil-fuels for example -on which we have built immense structures of routine expectation. — Rowan Williams

Climate change is not a major issue because it will cause sea level rises or temperature increases, since we know how to live at higher elevations and regulate the temperature within our homes. It is a major issue because ecosystems are finding it difficult to adapt to the rapidity of the climate and environmental changes and are dying off, thereby accelerating the species extinction that is already underway due to our consumption habits. — Shailesh Rao

Mass extinctions may not threaten distant futures, but they are decidedly unpleasant for species caught up in the throes of their power. — Stephen Jay Gould

Nevertheless so profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being; and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life! — Charles Darwin

The fate of hundreds of thousands of species on this planet may be decided in the next decade. To slow the rush to extinction, we need to achieve real, substantive political power, and we need to get there fast. — Eban Goodstein

When you're a hammer (as the saying goes), all your problems look like nails. If you're a meteorite expert pondering the sudden extinction of boatloads of species, you'll want to say an impact did it. If you're an igneous petrologist, volcanoes did it. If you're into spaceborne bioclouds, an interstellar virus did it. If you're a hypernova expert, gamma rays did it. — Neil DeGrasse Tyson

What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question. — Michael Crichton

Most of them are doomed to rapid extinction, but a few may make evolutionary inventions, such as physiological, ecological, or behavioral innovations that give these species improved competitive potential. — Ernst Mayr

The destiny of all species is extinction as such, fortunately for them. — T.H. White

Extinction, the irrevocable loss of a species, causes pain that can never find relief. It is an ache that will pass from generation to generation for the rest of human history. — Callum Roberts

I'm not saying we don't have our set of problems - climate crisis, species extinction, water and energy shortage - we surely do. [But] ultimately we knock them down. — Peter Diamandis

Looking around the world at these wildlife, it's abundantly clear that humans have benefited from nature in so many ways but have also brought many species to the brink of extinction ... The American people that I interact with through my IS Foundation work do not want to allow this to happen; they do not want to let these species go without a fight; and they see the way in which nature provides for people around the world. — Ian Somerhalder

With our evolved busy hands and our evolved busy brains, in an extraordinarily short period of time we've managed to alter the earth with such geologic-forcing effects that we ourselves are forces of nature. Climate change, ocean acidification, the sixth mass extinction of species. — Kate Bernheimer
