Who we are, what we do

Posted: 3 August 2010. Updated: 15 December 2016


Animal Defenders International (ADI) was founded in 1990. With offices in Los Angeles, London and Bogota, ADI educates and campaigns across the globe on animals in entertainment and other industries. We create public awareness of animal suffering and combine this with scientific and economic research. We provide technical briefings to legislators and governments. ADI has a worldwide reputation for providing video and photographic evidence exposing the behind-the-scenes suffering in industry and supporting this evidence with scientific research. ADI rescues animals all over the world and educates the public on animals and environmental issues. ADI in the UK is a registered non-profit membership guarantee company. ADI in the United States is a 501(c)(3) non-profit organization.

ADI takes a unique holistic, self-sufficient approach to achieving long-term protection for animals. We work at all levels, from start to finish of a campaign from investigations and gathering empirical evidence to scientific and economic research, publication of technical reports, through to public education and assisting with law enforcement and legal protection for animals.


We use our own photographs, video and research, and produce publications in-house. Our total production approach saves money and increases our outreach.

Two different campaigns exemplify this approach:

Our Stop Circus Suffering campaign in South America, which led to the historic ban on animal circuses in Bolivia, and saw us go from investigation to public education, legislative briefings resulted in a national animal circus ban, then moving to rescue animals freed by the ban.


Save the Primates, our biggest campaign of recent years about the new EU regulations on animals experiments. Working in multiple languages we produced scientific research and briefings on advanced non-animal research techniques. We finished the year with a rescue of laboratory monkeys that tied several of the core issues together.

Mission statement

ADI (founded 1990): To educate, create awareness, and promote the interest of humanity in the cause of justice, and the suppression of all forms of cruelty to animals; wherever possible, to alleviate suffering, and to conserve and protect animals and their environment.
