It can be hard to see a friend order a cow-milk latte when almond or soy milk is available, knowing that the friend knows what dairy cows go through, how they mourn their babies, who have been carted off to veal crates so that we can steal their milk.

Once people learn, it is hard to forget and go back.

Come for the body, stay for the soul.

Animal rights is a serious subject, but I do my best to find humor where I can, and I have some great help: there are almost two hundred cartoons included in the book, including dozens from the brilliant Bizarro strip.

When I see vegan food sold in single-use plastic containers, I get frustrated knowing that plastic is not really recycled; it is down-cycled to less and less reusable grades, and too much of it eventually ends up in the ocean - where it kills animals.
