Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can’t even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that’s on the Earth, to the, to the fowl that — that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth.
The insecticides kill the black flies, but also destroy much of the food chain for the bird, fish, and animal life which also inhabit those regions. The fish of the Great Lakes are laced with mercury from industrial plants, and fluoride from aluminum plants poisons the land and the people. Sewage from the population centers is mixed with PCBs and PBS in the watershed of the great lakes and the Finger Lakes, and the water is virtually nowhere safe for any living creatures.
The animals share with us the privilege of having a soul Alas, what wickedness to swallow flesh into our own flesh, to fatten our greedy bodies by cramming in other bodies, to have one living creature fed by the death of another! In the midst of such wealth as earth, the best of mothers, provides, yet nothing satisfies you, but to behave like the Cyclopes, inflicting sorry wounds with cruel teeth! You cannot appease the hungry cravings of your wicked, gluttonous stomachs except by destroying some other life.
Life is life's greatest gift. Guard the life of another creature as you would your own because it is your own. On life's scale of values, the smallest is no less precious to the creature who owns it than the largest.
People must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that such people can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections. It would be very strange that they should express so well what they could not feel.
Nature proceeds little by little from things lifeless to animal life in such a way that it is impossible to determine the exact line ure hath made one world, and art another. In brief, all things are artificial; for nature is the Art of God.
If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons.
