Earthlings is a documentary about mankind's dependence on animals for pets, food, clothing, entertainment, and use in experimentation.
The film documents the suffering of animals and some of the dreadful things we do to them. It was made in 2003, but it is still as shocking as it can be.
Few are able to watch it until the end. Most don't even make it to the first few minutes. You don't really want to know about these things.
Don't watch it, and keep pretending that there is no link between what we eat, what we wear, and the unbearable images in the film.
