On a personal note...
After reading Peter Singer's book "Animal Liberation", I've been vegan for 16 years. It's important to me to be part of the process of ending animal suffering in all areas.
My favorite veg and animal nonprofits are: Vegan Outreach, Mercy for Animals, Compassion over Killing, Farm Sanctuary, and so many more that are working to spread compassion and save lives.
My favorite veg and animal books are: The Animal Activist's Handbook, Striking at the Roots, Animal Liberation, Vegan for Life
