This I believe — that killing animals is wrong. The values and practices of vegetarianism are fairly straightforward. The vast majority of vegetarians hold the idea that killing animals is wrong, although others practice vegetarianism for environmental or health reasons. The practice is simple: you don’t eat meat.
Incidentally, I support the practices of renewable energy use, recycling, catalytic converters mandation, and personal energy efficiency. These practices support the ideology of environmentalism. There are strong images that go along with these practices — the recycle triangle, the tree with leaves consisting of environmentally friendly practices, and, most ubiquitously, the color green.
