The animals of the planet are in desperate peril1... Without free animal life I believe we will lose the spiritual equivalent of oxygen.

　　Alice Walker (1944 - ), Living by the Word, 1988

　　I am the Lorax, and I'll yell and I'll shout for the fine things on earth that are on their way out!

　　Dr. Seuss (1904 - 1991), The Lorax

　　I speak for the trees, for the trees have no tongues.

　　Dr. Seuss (1904 - 1991), The Lorax

　　Unless someone like you cares a whole awful lot, nothing is going to get better. It's not.

　　Dr. Seuss (1904 - 1991), The Lorax

　　What is the use of a house if you haven't got a tolerable planet to put it on?

　　Henry David Thoreau (1817 - 1862)

　　For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children's futures2, and we are all mortal.

　　John F. Kennedy (1917 - 1963), Speech at The American University, Washington, D.C., June 10, 1963

　　We shall never understand the natural environment until we see it as a living organism. Land can be healthy or sick, fertile or barren, rich or poor, lovingly nurtured3 or bled white. Our present attitudes and laws governing the ownership and use of land represent an abuse of the concept of private property.... Today you can murder land for private profit. You can leave the corpse4 for all to see and nobody calls the cops.

　　Paul Brooks, The Pursuit of Wilderness (1971)
