PeTA
PeTA focuses its attention on the four areas in which the largest numbers of animals suffer the most intensely for the longest periods of time: on factory farms, in laboratories, in the clothing trade, and in the entertainment industry. They also work on a variety of other issues, including the cruel killing of beavers, birds and other "pests," and the abuse of backyard dogs.

Vegan Outreach
VO is working to expose and end cruelty to animals through the widespread distribution of our illustrated booklets (pdfs): Why Vegan, Even If You Like Meat, and Try Vegetarian, along with our follow-up Guide. These are distributed by many people, from middle school students to animal advocacy organizations (FARM, Farm Sanctuary, The Fund for Animals, In Defense of Animals, Peta, Viva!USA, etc.).
