Top Carbon Dioxide Quotes

Everything on our dinner table-the meat, cheese, salad, bread, and soft drink-requires carbon dioxide to be there. For those of you who believe that carbon dioxide is a pollutant, we have a special diet: water and salt! — Joanne Nova

President Bush insisted today that he was not caving in to big money contributors, big-time lobbyists, and overall industry pressure when he broke a campaign promise to regulate carbon dioxide emissions from power plants. But the air was thick today with accusations from people who believe that's exactly what happened. — Dan Rather

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet. — John Olver

Carbon dioxide is portrayed as harmful. But there isn't even one study that can be produced that shows that carbon dioxide is a harmful gas. — Michele Bachmann

The science of fermentation is wonderfully simple. Yeast eat sugar. They leave behind two waste products, ethyl alcohol and carbon dioxide. If we were being honest, we would admit that what a liquor store sells is, chemically speaking, little more than the litter boxes of millions of domesticated yeast organisms, wrapped up in pretty bottles with fancy price tags. — Amy Stewart

The absorption of oxygen and the elimination of carbon dioxide in the lungs take place by diffusion alone. There is no trustworthy evidence of any regulation of this process on the part of the organism. — August Krogh

I believe everyone who breathes air on this earth, regardless of their job or their bank account, must give back more than just carbon dioxide. — Kelly Cutrone

Human releases of carbon dioxide are almost certainly happening faster than any natural carbon release since the beginning of life on Earth. — Mark Lynas

I am hoping that the scientists and politicians who have been blindly demonizing carbon dioxide for 37 years will one day open their eyes and look at the evidence. — Freeman Dyson

These are the oldest memories on earth, the time codes carried in every chromosome and gene. Every step we've taken in our evolution is a milestone inscribed with organic memories. From the enzymes controlling the carbon-dioxide cycle, to the organization of the brachial plexus and the nerve pathways of the pyramid cells of the mid-brain. Each is a record of a thousand decisions taken in a chemical crisis. Just as psychoanalysis reconstructs the original traumatic situation in order to release the repressed material, so we are now being plunged back into the archaeopsychic past, uncovering the ancient taboos and drives that have been dormant for epochs. — J.G. Ballard

The concentration of atmospheric carbon dioxide has changed greatly since fossilized life began on Earth nearly 600 million years ago. In fact, there is only 1/19 as much CO2 in the air today as there was 520 million years ago. That high CO2 was hardly the recipe for disaster. — Greg Benson

Those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It's pure guesswork. — Henrik Svensmark

Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady. — Sylvia Earle

Centuries-old habitats such as coral gardens are destroyed in an instant by bottom trawls, pulverized by weighted nets into barren plains. And global carbon dioxide emissions from human activity affect the ocean, changing the pH balance of the waters in a phenomenon known as ocean acidification. — Ted Danson

Our early 21st century civilization is in trouble. We need not go beyond the world food economy to see this. Over the last few decades we have created a food production bubble-one based on environmental trends that cannot be sustained, including overpumping aquifers, overplowing land, and overloading the atmosphere with carbon dioxide. — Lester R. Brown

Lambic is flat, since all carbon dioxide produced during lambic fermentation escapes from the barrel. Packaged young, lambic develops carbonation in a manner similar to a cask or bottle of real ale. Real ale is casked or bottled at the end of fermentation with just enough fermentable sugar left in solution to provide a gentle carbonation. The microorganisms responsible for lambic fermentation can consume virtually any type of sugar; therefore, the brewer never bottles young lambic. The fermentation of the remaining sugar in young lambic would produce enough carbon dioxide to shatter the bottle. — Jeff Sparrow

Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life - the carbohydrates, amino acids, proteins, and lipids - is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air. — Michael Pollan

It will be nearly impossible to slow warming appreciably without condemning much of the world to poverty unless energy sources that emit little or no carbon dioxide become competitive with conventional fossil fuels. — Henry Sylvester Jacoby

If you choose to make regulations about carbon dioxide, that's OK. You as a state can do that; you have a right to do it. But it's not going to do anything about the climate. And it's going to cost, there's no doubt about that. — John Christy

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning. — Sylvia Earle

The simplest way to remove carbon dioxide, the main greenhouse gas, is to grow plants - preferably trees, since they tie up more of the gas in cellulose, meaning it will not return to the air within a season or two. Plants build themselves out of air and water, taking only a tiny fraction of their mass from the soil. — Gregory Benford

I am not convinced the Clean Air Act was ever intended to regulate or classify as a dangerous pollutant something as basic and ubiquitous in our atmosphere as carbon dioxide. — Jim Webb

The scientific facts indicate that all the temperature changes observed in the last 100 years were largely natural changes and were not caused by carbon dioxide produced in human activities. — Robert Jastrow

The biggest gains, in terms of decreasing the country's energy bill, the amount of carbon dioxide we put into the atmosphere, and our dependency on foreign oil, will come from energy efficiency and conservation in the next 20 years. Make no doubt about it. That's where everybody who has really thought about the problem thinks the biggest gains can be and should be. — Steven Chu

Life isn't just about taking in oxygen and giving out carbon dioxide. — Malala Yousafzai

When you have energy companies like Shell and British Petroleum, both of which are perhaps represented in this room, saying there is a problem with excess carbon dioxide emission, I think we ought to listen. — James Baker

Washington bureaucrats have classified the very air we exhale as a pollutant and have gone unchallenged in this incredible assertion. The logical consequence is that there will come a time when we will have to buy a government permit just to emit carbon dioxide into the atmosphere from our own lungs! — Ron Paul

Organisms in the ocean provide over 40 percent of the oxygen we breathe, and they're the major sink for capturing all the carbon dioxide we constantly release into the atmosphere. — Craig Venter

The leaves on our little maple, all taken together, weigh thirty-five pounds. Every ounce therein must be pulled from the air or mined from the soil - and quickly - over the course of a few short months. From the atmosphere, a plant gains carbon dioxide, which it will make into sugar and pith. Thirty-five pounds of maple leaves may not taste sweet to you and me, but they actually contain enough sucrose to make three pecan pies, which is the sweetest thing that I can think of right now. The pithy skeleton within the leaves contains enough cellulose to make almost three hundred sheets of paper, which is about the number that I used to print out the manuscript for this book. Our — Hope Jahren

Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using it. — James Hansen

The retreat of the Arctic sea ice, the warming of the oceans, the rapid shrinking of the glaciers, the redistribution of species, the thawing of the permafrost - these are all new phenomena. It is only in the last five or ten years that global warming has finally emerged from the background "noise" of climate variability. And even so, the changes that can be seen lag behind the changes that have been set in motion. The warming that has been observed so far is probably only about half the amount required to bring the planet back into energy balance. This means that even if carbon dioxide were to remain stable at today's levels, temperatures would still continue to rise, glaciers to melt, and weather patterns to change for decades to come. — Elizabeth Kolbert

No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science. — William Happer

Climate change is a crucial issue in todays global agenda. Hopefully, we will wake up to this reality, sooner rather than later. Pressure has been mounting on European Union Member States to act decisively to fight global warming. A bold target has been set reducing carbon dioxide emissions by 20 by 2020. — Joseph Muscat

We can't conclusively say whether man-made carbon dioxide emissions are contributing to climate change. — Tony Abbott

Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil. — Frances Beinecke

Food now represents the single largest component of municipal solid waste brought to landfills, where it also releases methane, a greenhouse gas 34 times more potent than carbon dioxide. And if that weren't enough, it costs Americans $1.5 billion a year just to dispose of the wasted food.17 The impacts of food waste are not limited to the United States, however. The footprint of food that is lost or wasted across the globe is estimated as follows. 28 percent of all agricultural land - an area larger than Canada18 38 times the volume of water used by all U.S. households19 3.3 billion metric tons of carbon dioxide equivalent; if it were a country, uneaten food would be third in its greenhouse gas footprint, after the United States and China20 — Dana Gunders

I don't like being called a denier because deniers don't believe in facts. There are no facts linking the concentration of atmospheric carbon dioxide with imminent catastrophic global warming there are only predictions based on complex computer models. — David Bellamy

Blue-green algae, or cyanobacteria, were the first photosynthesizers. They breathed in carbon dioxide and breathed out oxygen. Oxygen is a volatile gas; it causes iron to rust (oxidation) and wood to burn (vigorous oxidation). When cyanobacteria first appeared, the oxygen they breathed out was toxic to nearly all other forms of life. The resulting extinction is called the oxygen catastrophe. After the cyanobacteria pumped Earth's atmosphere and water full of toxic oxygen, creatures evolved that took advantage of the gas's volatile nature to enable new biological processes. We are the descendants of those first oxygen-breathers. Many details of this history remain uncertain; the world of a billion years ago is difficult to reconstruct. — Randall Munroe

Coral reefs, the rain forest of the ocean, are home for one-third of the species of the sea. Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide. Ocean life dependent on carbonate shells and skeletons is threatened by dissolution as the ocean becomes more acid. — James Hansen

Trees and soils can absorb carbon dioxide released by fossil fuel burning. It would be great to subsidize responsible farmers and forest managers. — Alana Beard

I have never met a geologist or leading scientist who believes adding more carbon dioxide to the atmosphere will have any significant effect on climate change. — Gina Rinehart

All this argument is the temperature going up or not, it's absurd ... Of course it's going up. It has gone up since the early 1800s, before the Industrial Revolution, because we're coming out of the Little Ice Age, not because we're putting more carbon dioxide into the air. — Reid Bryson

Climate is not responding to greenhouse gases in the way we thought it might. If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. People are being misled by people making money out of this. — Chris De Freitas

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other. — Piers Corbyn

When Glacier Park was established in 1910, it had about 150 glaciers. Today, with human activities spewing carbon dioxide and methane as if we were intent on re-creating Earth's ancient atmosphere, a warming climate has reduced the number of glaciers to 25, and thoses are shrinking three to four times as fast as they were just half a century ago. The last one is expected to vanish by 2020. — Douglas Chadwick

In the Gaia theory air, water, and soil are major components of one central organism, planet Earth. What we typically think of as life - the plants and animals that inhabit the earth - has evolved merely to regulate the chemistry of the biosphere. Humans are insignificant participants, far less important to the life cycle than termites. Even the imbalance that we have created by adding massive quantities of carbon dioxide to the atmosphere may be brought back to acceptable levels by other organisms functioning in their capacity to correct excesses. — David Easton

Electricity generation emits more carbon dioxide in the United States than does transportation or industry, and nuclear power is the largest source of carbon-free electricity in the country. — Ernest Moniz

Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname 'the other carbon problem.' As they do so, the oceans become more acidic with terrible consequences. — Philippe Cousteau Jr.

Society's emissions of carbon dioxide may or may not turn out to have something significant to do with global warming-the jury is still out. — Edward Teller

What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile. — James Hansen

When I was a boy in the 1930s, the carbon dioxide level was still below 300 parts per million. This year, it reached 382, the highest figure for hundreds of thousands of years. — David Attenborough

Essentially, by 2050 we need all activities outside agriculture to be near zero carbon emitting if we are to stop carbon dioxide levels in the atmosphere growing — David Miliband

There is no doubt there is more carbon dioxide in the atmosphere, caused by the burning of fossil fuels. It should have an effect on the climate, but the numbers indicate that effect is relatively minor. — John Christy

...the only thing that could justify your continuing existence on the planet would be if you started breathing carbon dioxide and exhaling oxygen. — Yrsa Sigurdardottir

He could taste the familiar tang of museum air - an arid, deionized essence that carried a faint hint of carbon - the product of industrial, coal-filter dehumidifiers that ran around the clock to counteract the corrosive carbon dioxide exhaled by visitors. — Dan Brown

Claiming that a little piece of green paper is more important than, say, the tree it's made from - even though that tree provides oxygen and absorbs carbon dioxide from the atmosphere. Without the trees, we would all die out, but cash is an invention that is less than two thousand years old. — Bella Forrest

Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful. — Frederick Seitz

The world beyond 450 ppm atmospheric concentrations of carbon dioxide, the world that crosses carbon cycle tipping points that quickly take us to 1000 ppm, is a world not merely of endless regional resource wars around the globe. It is a world with dozens of Darfurs. It is a world of a hundred Katrinas, of countless environmental refugees — Joseph J. Romm

The burning of fossil fuels has altered the amount of carbon dioxide in the atmosphere so rapidly and so abundantly that now, we are driving not just the warming trend, not just the sea level rise that is a consequence of the warming trend that is melting polar ice and alpine ice, but also [ocean acidification]. — Sylvia Earle

What a difference that extra 120 ppm has made for plants, and for animals and humans that depend on them. The more carbon dioxide there is in the atmosphere, the more it is absorbed by plants of every description - - and the faster and better they grow, even under adverse conditions like limited water, extremely hot air temperatures, or infestations of insects, weeds and other pests. As trees, grasses, algae and crops grow more rapidly and become healthier and more robust, animals and humans enjoy better nutrition on a planet that is greener and greener. — Paul Driessen

They absorb carbon monoxide and carbon dioxide and give out oxygen. What could be more desirable? And they look good in the bargain. Stop chopping down the rain forests and plant more saplings, and we're on our way. — Isaac Asimov

If we want to stabilize the carbon dioxide in the atmosphere at some level - it really doesn't matter which level - you end up having to stop emissions virtually completely. — Klaus Lackner

[W]hen we look at the graphs of rising ocean temperatures, rising carbon dioxide in the atmosphere and so on, we know that they are climbing far more steeply than can be accounted for by the natural oscillation of the weather ... What people (must) do is to change their behavior and their attitudes ... If we do care about our grandchildren then we have to do something, and we have to demand that our governments do something. — David Attenborough

I find it sad, but all too human, that there are vast bureaucracies concerned about nuclear waste, huge organizations devoted to decommissioning nuclear power stations, but nothing comparable to deal with that truly malign waste, carbon dioxide. — James E. Lovelock

The first demonstration of the law of conservation of energy was not by a physicist but by a medical man. He demonstrated with rats. If you burn food you can find out how much heat is generated. If you then feed the same amount of food to rats it is converted, with oxygen, into carbon dioxide, in the same way as in burning. When you measure the energy in each case you find out that living creatures do exactly the same as non-living creatures. The law for conservation of energy is as true for life as for other phenomena. Incidentally, — Richard Feynman

Carbon dioxide is unusual because it doesn't go through the usual three phases of matter, from solid to liquid to gas, but it goes straight from solid to gas. The volume of the gas is much greater than the volume of the solid. When a solid turns into a gas, we say it sublimes. The process is sublimation. — Robert Winston

Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone. — Seth Shostak

I know that nuclear is better than fossil fuels when it comes to carbon dioxide, but nuclear energy is by no means clean. We don't know what to do with the waste we already have and it seems like a bad idea to me to make more when we have so many cleaner options such as wind and solar. — Sheryl Crow

We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere ... can handle before there is an environmental catastrophe. — Elon Musk

In the course of the 1920s and 1930s, great progress was made in the study of the intermediary reactions by which sugar is anaerobically fermented to lactic acid or to ethanol and carbon dioxide. — Hans Adolf Krebs

Air is one we hold in common; it has a limited carrying capacity for pollutants and that's being used up by those who pollute the atmosphere. So we have to stop that externality. We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane. — Jay Inslee

I have not been one who believed in the global warming. But I tell you, they are making a convert out of me as these blistering summers. They have broken heat records in a number of cities already this year and broken all-time records and it is getting hotter and the ice caps are melting and there is a build up of carbon dioxide in the air. We really need to address the burning of fossil fuels. — Pat Robertson

Carbon dioxide does not cause or contribute to smog, and the Kyoto treaty would do nothing to reduce or prevent smog. — Stephen Harper

If food was no longer obliged to make intercontinental journeys, but stayed part of a system in which it can be consumed over short distances, we would save a lot of energy and carbon dioxide emissions. And just think of what we would save in ecological terms without long-distance transportation, refrigeration, and packaging
which ends up on the garbage dump anyway
and storage, which steals time, space, and vast portions of nature and beauty. — Carlo Petrini

Southam's research was only one of hundreds of similarly unethical studies. Beecher published a detailed list of the twenty-two worst offenders, including researchers who'd injected children with hepatitis and others who'd poisoned patients under anesthesia using carbon dioxide. Southam's study was included as example number 17. Despite scientists' fears, the ethical crackdown didn't slow scientific progress. In fact, research flourished. And much of it involved HeLa. — Rebecca Skloot

Many people I've met believe that plants are made up of soil-that the tree outside your house, for example, is mostly made from the soil in which it grew. That's a common mistake. That tree is mostly made up of one of the gases in our air (carbon dioxide) and water (hydrogen and oxygen). Trees are solidified air and sunlight. — Thom Hartmann

The coal plants that will be built from 2005 to 2030 will release as much carbon dioxide as all of the coal burned since the industrial revolution more than two centuries ago. — Joseph J. Romm

The key players are now all in place in Washington and in state governments across America to officially label carbon dioxide as a pollutant and enact laws that tax us citizens for our carbon footprints. — John Coleman

NASA's Aqua satellite is showing that water vapor, the dominant greenhouse gas, works to offset the effect of carbon dioxide (CO2). This information, contrary to the assumption used in all the warming models, is ignored by global warming alarmists. — Walter Cunningham

The planet needs trees. If there is indeed that carbon dioxide out there in the atmosphere, the only species on the planet that can actually trap it for us in a natural process of photosynthesis are the trees. — Wangari Maathai

The human eye has to be one of the cruelest tricks nature ever pulled. We can see a tiny, cone-shaped area of light right in front of our faces, restricted to a very narrow band of the electromagnetic spectrum. We can't see around walls, we can't see heat or cold, we can't see electricity or radio signals, we can't see at a distance. It is a sense so limited that we might as well not have it, yet we have evolved to depend so heavily on it as a species that all other perception has atrophied. We have wound up with the utterly mad and often fatal delusion that if we can't see something, it doesn't exist. Virtually all of civilization's failures can be traced back to that one ominous sentence: 'I'll believe it when I see it.' We can't even convince the public that global warming is dangerous. Why? Because carbon dioxide happens to be invisible. — David Wong

The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit ... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year. — Bill McKibben

[The doctrine of air] I was led into in consequence of inhabiting a house adjoining to a public brewery, where I at first amused myself with making experiments on the fixed air [carbon dioxide] which I found ready made in the process of fermentation . When I removed from that house I was under the necessity of making the fixed air for myself; and one experiment leading to another, as I have distinctly and faithfully noted in my various publications on the subject, I by degrees contrived a convenient apparatus for the purpose, but of the cheapest kind. — Joseph Priestley

those natural releases are almost perfectly balanced by natural processes that absorb carbon dioxide. For — Jeffrey Bennett

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide. — Stephen Hawking

Many people think trees grow so big from soil and water, but this is not true. Trees get their mass from the air. They gobble up airborne carbon dioxide and perform an act of chemical fission by using the energy from sunshine ... Essentially, trees are made of air and sunshine. — Ned Hayes

Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000. — Carl Sagan

Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees. — Jamais Cascio

Al Gore likes to say that mankind puts 70 million tons of carbon dioxide into the atmosphere every day. What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas-water vapor-into the atmosphere every day and removes about the same amount every day. While this does not 'prove' that global warming is not man-made, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds. — Roy Spencer

I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have a tipping point for atmospheric carbon dioxide, it's just nonsense. — Burt Rutan

Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can't even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that's on the Earth, to the, to the fowl that - that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth. — Michele Bachmann

So, if we decrease the use of carbon dioxide, are we not taking away plant food from the atmosphere? — John Shimkus

Writing is my oxygen. Music is my carbon dioxide. — Jessica Bell

We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life. — James Hansen

Whether it is to reduce our carbon-dioxide emissions or to prepare for when the coal and oil run out, we have to continue to seek out new energy sources. — Martin Rees

I can't believe that Hillary Clinton wants the world to think that whenever she gets into political trouble, she's going to have her husband come roaring about, breaking furniture, sucking up oxygen, spewing carbon dioxide. My impression is that she's strong enough to defend herself - she certainly showed that in the recent Democratic debate. But apparently she's not strong enough to control Mr. Bill ... and if that's the case, any sane voter would have to think twice before enabling this sort of circus act in the White House. — Joe Klein

Just about every generation has some horrific evil that it must fight. For the Democratic Party today that evil is carbon dioxide emissions. For the rest of us, it is an ideology that teaches that its deity is sanctified by the blood of innocents. — Dennis Prager

I can't believe that we have reached the end of everything. The red dust is frightening. The carbon dioxide is real. Water is expensive. Bio-tech has created as many problems as it has fixed, but we're here, we're alive, we're the human race, we have survived wars and terrorism and scarcity and global famine, and we have made it back from the brink, not once but many times. History is not a suicide note - it's a record of our survival. — Jeanette Winterson

These things are happening in large measure because of us. We in this country burn 25 percent of the world's fossil fuel, create 25 percent of the world's carbon dioxide. It is us - it is the affluent lifestyles that we lead that overwhelmingly contribute to this problem. And to call it a problem is to understate what it really is. Which is a crime. Crime against the poorest and most marginalized people on this planet. We've never figured out, though God knows we've tried, a more effective way to destroy their lives. — Bill McKibben
