“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.”

“We are the intelligent elite among animal life on earth and whatever our mistakes, [Earth] needs us. This may seem an odd statement after all that I have said about the way 20th century humans became almost a planetary disease organism. But it has taken [Earth] 2.5 billion years to evolve an animal that can think and communicate its thoughts. If we become extinct she has little chance of evolving another.”

“This is my manifesto. My attempt to nudge people toward something, or back toward something. Toward what? An understanding that most of us already have on a deeper level. That a world exists outside of us. A world that reminds us that we are animals, too, animals who have evolved along with other animals on this earth. Thinking, planning, scheming, talking, writing animals, but animals nonetheless.”

“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.”

“When viewed at the next quantum level of perspective, from which the Earth is seen as an organism and humans are seen as microorganisms, the human species looks like a menace to the planet. In fact, the human race is looking a lot like a disease -- comprised of organisms excessively multiplying, mindlessly consuming, and generating waste with little regard for the health and well-being of its host -- planet Earth.”

“And now that we have returned to the desultory life of the plain, let us endeavor to import a little of that mountain grandeur into it. We will remember within what walls we lie, and understand that this level life too has its summit, and why from the mountain-top the deepest valleys have a tinge of blue; that there is elevation in every hour, as no part of the earth is so low that the heavens may not be seen from, and we have only to stand on the summit of our hour to command an uninterrupted horizon.”

“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.”
