For the next two weeks, philosophers will be fundraising for one of the world's most effective charities - the Humane League (THL). The Humane League fights factory farming by persuading individuals and organizations to adopt behaviors and policies that reduce farmed animal suffering.

THL has a very good claim to being among the best animal advocacy organizations in the world. They are the only organization to have been rated a top charity by independent research organization Animal Charity Evaluators during every period of its existence. THL is committed to evidence-based advocacy, regularly undertaking and publishing research through Humane League Labs, to identify and act on best practices in animal advocacy, and is widely celebrated in the Effective Altruism movement.

Farmed animal suffering is a pressing and under-recognised issue of staggering dimensions, with over 60 billion terrestrial animals and many more fish raised and killed in factory farms each year globally. These animals endure a lifetime of suffering, typically confined in crates so small that they cannot turn around or walk a single step, and subjected to numerous painful industry practices, such as tail-docking and debeaking without anesthesia. The Humane League exists to help combat and ultimately end these practices.

THL works towards this goal through a combination of corporate campaigns and grassroots outreach. Animal Charity Evaluators estimates that, in 2017, THL’s corporate campaigns will help cause 60–190 policy changes affecting 100 million–3 billion laying hens and broiler chickens each year. Their grassroots outreach exposes hundreds of thousands to carefully-tailored leaflets, videos, and humane education presentations, and in 2016 they were instrumental in mobilizing a victorious campaign banning the worst forms of confinement for calves, hens, and pigs in the state of Massachusetts.

By donating to THL, you can help save thousands of lives and move us ever closer to making factory farming history!
