What is man without the beasts? If all the beasts were gone, men would die from great loneliness of spirit, for whatever happens to the beasts also happens to man … Teach your children what we have taught our children: that the earth is their mother. Whatever befalls the earth befalls the sons of the earth. If men spit upon the ground, they spit upon themselves. The earth does not belong to man, man belongs to the earth. Man does not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself.
— Chief Seattle of the Squamish tribe
