Earth is our home ... the largest living creature in our solar system. The land, the water, the air, and all the things that live on and in them form a gigantic community, an enormous cell. Here fungi, eagles, toads, worms, grasses, mosquitoes, ferns, people, dolphins, spiders, oak trees, and lions — up to ten million separately distinguishable forms of life or species — share Earth's environments. Whatever happens to one part, for good or ill, ultimately affects us all, the whole Earth: our home of abundant riches and indescribable beauty.
