The Humane League takes a "bottom line" approach to animal advocacy: we invest our time, money and energy where they will do the most good for the greatest number of animals.

As a result our programs focus mainly on farmed animal issues. Farmed animals represent over 98% of the animals used and killed in the United States, and because they are excluded from state anti-cruelty laws they suffer intensely on today's "factory farms."

Because social change happens on both the personal and institutional levels, our work addresses both. We work to create meaningful, long-term social change through shifting the attitudes and behaviors of individual members of the public, motivating them to move towards vegetarian and vegan eating and providing resources to help them along. We also campaign for institutional policy changes that improve the lives of farmed animals by getting institutions to stop purchasing products from facilities that use very intensive confinement practices such as the battery cage system.

Our primary programs are humane education, vegetarian advocacy (in a variety of forms), and our cage-free campaign.
