Animals rights

Animal abuse is unbearable, and it is important to give rights to animals. For more than three decades, the Animal Legal Defense Fund (ALDF) has been fighting to protect the lives and advance the interests of animals through the legal system, pushing government agencies to do their jobs to protect animals and shining a national spotlight on issues like factory farming and dissection in schools.
