A Quote by Roger Revelle

Thus, human beings are now carrying out a large scale geophysical experiment of the kind that could not have happened in the past...Within a few centuries we are returning to the atmosphere and oceans the concentrated organic carbon stored in sedimentary rocks over hundreds of millions of years.

Like the ocean, land plants hold about three times as much carbon as the atmosphere. While oceans take many centuries to exchange this mass with the air, flora take only a few years.

Gregory Benford

We will never know everything. But I think if we can learn within the next few decades to face the danger we all are in, I believe there will be tens of millions, maybe hundreds of millions, of human beings working wherever they are to do something good.

Pete Seeger

You have noticed that the human being is a curiosity. In times past he has had (and worn out and flung away) hundreds and hundreds of religions; today he has hundreds and hundreds of religions, and launches not fewer than three new ones every year. I could enlarge on that number and still be within the facts.

Mark Twain

I look at it this way... For centuries now, man has done everything he can to destroy, defile, and interfere with nature: clear-cutting forests, strip-mining mountains, poisoning the atmosphere, over-fishing the oceans, polluting the rivers and lakes, destroying wetlands and aquifers... so when nature strikes back, and smacks him on the head and kicks him in the nuts, I enjoy that. I have absolutely no sympathy for human beings whatsoever. None. And no matter what kind of problem humans are facing, whether it's natural or man-made, I always hope it gets worse.

George Carlin

I must confess that I am deeply troubled. I fear that human beings are intent upon acting out a vast deathwish and that it lies with us now to make every effort to promote resistance to the insanity and brutality of policies which encompass the extermination of hundreds of millions of human beings.

Bertrand Russell

The essential fact which emerges ... is that the three smallest and most active reservoirs ( of carbon in the global carbon cycle), the atmosphere, the plants and the soil, are all of roughly the same size. This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.

Freeman Dyson

The rapid progress of the sciences makes me sorry, at times, that I was born so soon. Imagine the power that man will have over matter, a few hundred years from now. We may learn how to remove gravity from large masses, and float them over great distances. Agriculture will double its produce with less labor. All diseases will surely be cured... even old age. If only the moral sciences could be improved as well. Perhaps men would cease to be wolves to one another... and human beings could learn to be human.

Benjamin Franklin

The Second World War is the largest single event in human history, fought across six of the world's seven continents and all it oceans. It killed 50 million human beings, left hundreds of millions of others wounded in mind or body and materially devastated much of the heartland of civilization.

John Keegan

Coal, oil and gas are called fossil fuels, because they are mostly made of the fossil remains of beings from long ago. The chemical energy within them is a kind of stored sunlight originally accumulated by ancient plants. Our civilization runs by burning the remains of humble creatures who inhabited the Earth hundreds of millions of years before the first humans came on the scene. Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives. - Dr. Carl Sagan

Carl Sagan

Human activity is having a major impact on the planet. We consume or have diverted a large proportion of the productivity of the land and oceans. Our hunger for land crowds out fellow species. Our waste products pollute the waters, warm the atmosphere and acidify the oceans.

Ian Goldin

Over the past few years, many of us have increasingly begun to question the direction and meaning of our society as it has developed over the past several centuries.

Alex Campbell

When whales die, their bodies sink to the bottom of the ocean and over time become part of the marine sediment layer, where they can sequester the carbon dioxide they have accumulated during their life span, an average of 33 tons for a great whale species, keeping it out of the atmosphere for hundreds or thousands of years.

Tatiana Schlossberg

Mass literacy is a phenomenon of the past few centuries, and one that has reached the majority of the world's adult population only within the past 75 years.

Tom Chatfield

The action we take in the next few years will impact the Earth hundreds of millions of years from now.

Louie Psihoyos

It's stupid to claim that one human being is special, or picked out by God, when in fact there are hundreds of millions of human beings in the world, and God knows how many millions of people long dead who have been lost to history, all of whom were probably special to someone.

Louis de Bernieres

I had a foretaste of another, larger kind of knowledge: one I believe human beings will be able to access in ever larger numbers in the future. But conveying that knowledge now is rather like a chimpanzee, becoming a human for a single day to experience all of the wonders of human knowledge, and then returning to one's chimp friends and trying to tell them what it was like knowing several different Romance languages, the calculus, and the immense scale of the universe.
