A large animal needs a large area. If you protect that area, you're also protecting thousands of other plants and animals. You're saving all these species that future generations will want - you're saving the world for your children and your children's children. . . . The destruction of species is final. If you lose a species, you lose the genes, you lose all the potential drugs and potential foods that could be useful to the next generations. The ecosystems will not function as they have.

If the bee disappeared off the face of the earth, man would only have four years left to live.

Grass is the forgiveness of nature - her constant benediction. Forests decay, harvests perish, flowers vanish, but grass is immortal...Its tenacious fibers hold the earth in place and prevent its soluble components from washing to the wasting sea.

If one truly loves nature one finds beauty everywhere.

Contrary to popular belief, we do not face a choice between economy and ecology, It is often said that protecting the environment would constrain or even undermine economic growth. In fact, the opposite is true: unless we protect resources and the earth's natural capital, we shall not be able to sustain economic growth.

Compared with me, a tree is immortal.
