I haven’t eaten meat in nearly a month after reading an article by Peter Singer, entitled, “Environmental Values.”
It contains a strong argument against “speciesism” the belief that the human race is superior to all other beings for various reasons, one of them being the capacity to reason. However, it should be acknowledged that animals are sentient creatures, and capable of feeling pain. This view is utilitarian, due to the hedonic consideration of all the creatures involved, including humans.
My belief that animals deserve equal consideration is founded on the sheer amount of suffering farm animals undergo. No man would be castrated and plow fields until he dies. No woman would want to be milked by a cow.
In Singer’s article there is a difference between “shallow” and “deep ecology.” Shallow ecology pretty much entails what I’ve written, only sentient creatures need apply. However deep ecology, the reverence of bacteria say, creates problems. Should we not wash our hands in order to save the microbes, should we only drink dirty water? Surely we shouldn’t let viruses thrive in our immune systems? The answer of course not, saving viruses is not a defensible position.
However, a rare flower might have intrinsic aesthetic value. Other parts of the environment such as forests and deserts may provide shelter and food for sentient creatures besides humans. Therefore ecosystems are worth saving. They are not merely aesthetic. We have an obligation to be kind to animals.
