What sets HSI apart

Active on nearly every continent, HSI is one of the few international animal protection organizations working to protect all animals—including animals in laboratories, farm animals, companion animals and wildlife.

We are deeply committed to extending our reach and to expanding our services and support to local organizations around the world.

HSI campaigns around the world to help the greatest possible number of animals and to save those who are suffering from the most severe abuse, investing our time, effort and resources in ways that will make a real difference. Learn more about our multinational areas of focus.
