There is, however, a moral basis for the vegetarian diet for which the indeterminate value of an animal's life takes on irrelevance. And that moral basis is a concern for the environment, a value as absolute as the value we all place on human life, since humanity will not survive for long on a poisoned planet. To be an environmentalist who happens to eat meat is like being a philanthropist who doesn't happen to give to charity.

You can't change yesterdays, but you can change tomorrows.

You, (my meat-eating friends), put your health at risk – that’s your business. But animal-based diets put the land, the water, the air, a society’s collective health, and even our collective pharmaceutical resources at risk. That’s my business. That’s everyone’s business.

If you visit the killing floor of a slaughterhouse, it will brand your soul for life.

For those who are still merely vegetarian and not yet vegan, I ask, what in heaven's name are you waiting for?

Everything revolves around the fork.
