We have since defined Gaia as a complex entity involving the Earths bi — James Lovelock

"Challenging the conventional wisdom is the way to make waves in science."

"The climate and the chemical properties of the Earth now and throughout its history seem always to have been optimal for life. For this to have happened by chance is as unlikely as to survive unscathed a drive blindfold through rush hour traffic."

"In the current fashionable denigration of technology, it is easy to forget that nuclear fission is a natural process. If something as intricate as life can assemble by accident, we need not marvel at the fission reactor, a relatively simple contraption, doing likewise."

"Our planet... consists largely of lumps of fall-out from a star-sized hydrogen bomb...Within our bodies, no less than three million atoms rendered unstable in that event still erupt every minute, releasing a tiny fraction of the energy stored from that fierce fire of long ago."

"Life has to take charge of its environment and evolve with it."

"If there were a billion people living on the planet, we could do whatever we please. But there are nearly seven billion. At this scale, life as we know it today is not sustainable."

"Be the change that you wish to see in the world."

"we are engaged in a grim experiment never before attempted. We are subjecting whole populations to exposure to chemicals which animal experiments have proved to be extremely poisonous and in many cases cumulative in their effect. These exposures now begin at or before birth and-unless we change our methods-will continue through the lifetime of those now living. No one knows what the result will be, because we have no previous experience to guide us."

"pity this busy monster, manunkind, not. Progress is a comfortable disease: your victim (death and life safely beyond) plays with the bigness of his littleness"

"I believe that the unity of man as opposed to other living things derives from the fact that man is the conscious life of himself. Man is conscious of himself, of his future, which is death, of his smallness, of his impotence; he is aware of others as others; man is in nature, subject to its laws even if he transcends it with his thought."

"“We need brains, is the bottom line,” Ivy said. “We’re not hunter-gatherers anymore. We’re all living like patients in the intensive care unit of a hospital. What keeps us alive isn’t bravery, or athleticism, or any of those other skills that were valuable in a caveman society. It’s our ability to master complex technological skills. It is our ability to be nerds. We need to breed nerds.”"

"I have been clinically depressed for most of my life. I once used drugs to fix it. Then I stopped. I stopped because I decided they were making me stupid, and Id rather be miserable than stupid. I am what I am."
