Animal Liberation is a movement that advocates for the rights and welfare of non-human animals. It seeks to end practices that exploit animals for food, clothing, entertainment, and research. Proponents argue that animals have the right to live free from suffering and exploitation, similar to human rights. The philosophy of Animal Liberation is often associated with the work of Peter Singer, who published the influential book "Animal Liberation" in 1975. This movement encourages people to consider the ethical implications of their choices and promotes alternatives, such as a vegan lifestyle, to reduce harm to animals.
