Our green, leafy friends lack faces and voices, but below the surface, they possess a surprising sensitivity and a desperate will to remain alive and unharmed. The New York Times questions the ethics of vegetarianism:
Surely, I’d thought, science can defend the obvious, that slaughterhouse carnage is wrong in a way that harvesting a field of lettuces or, say, mowing the lawn is not. But instead, it began to seem that formulating a truly rational rationale for not eating animals, at least while consuming all sorts of other organisms, was difficult, maybe even impossible.
The differences that do seem to matter are things like the fact that plants don’t have nerves or brains. They cannot, we therefore conclude, feel pain. In other words, the differences that matter are those that prove that plants do not suffer as we do. Here the lack of a face on plants becomes important, too, faces being requisite to humans as proof not only that one is dealing with an actual individual being, but that it is an individual capable of suffering.
