The transformations initiated by a healthy vegan diet go well beyond physical health. For those who want it to be, a plant-based diet is also a poten… - James E. McWilliams

The “animal rights movement” … is at once colossally powerful but ultimately hobbled by a weak spot both miniscule and fatal. … That colossal power emanates from hundreds of thousands of everyday activists who justifiably believe that conscientious consumers can, through a wide variety of measures, take gradual steps toward removing animal products from their diet. These true believers do the grunt work of activism: they hand out pamphlets, write books, blog, make documentaries, start campus veg societies, publish vegan recipes, open vegan food carts, work for animal sanctuaries, run veganic farms, and do basically anything they can to encourage consumers to contemplate the face on their plate. I consider myself a member of this noble tribe. The heel of the movement, by contrast, consists of a handful of radicals, mostly academics, who do little more than set an unrealistic benchmark of success … First, it seeks to eliminate all animal exploitation, in every realm of life, immediately, and without compromise or strategic capitulation; and second, it aims to eliminate all forms of oppression … The heel does not want the good, or even the better. It wants perfection.

Nobody wants to cook "Five Spice Stew With a Mother Deer Shot With a High-Powered Rifle While Her Baby Slept Nearby." But what about "Five Spice Venison Stew"? Much more palatable. … But when we tell ourselves that we're humanely harvesting venison out of reverence for the deer -- rather than killing a sentient being to satisfy our palate -- we're not so much connecting with our food as we are manipulating language to avoid knowing what we don't want to know.

In the case of agriculture and drought, there’s a clear and accessible action most citizens can take: reducing or, ideally, eliminating the consumption of animal products. Changing one’s diet to replace 50 percent of animal products with edible plants like legumes, nuts and tubers results in a 30 percent reduction in an individual’s food-related water footprint. Going vegetarian, a better option in many respects, reduces that water footprint by almost 60 percent.
