Earthlings

I just remembered I saw this documentary a few months ago and it correlates to animals. It's extremely graphic and sheds light on how animals are used in our current society.

For more information, this is the plot summary from the Wikipedia page:
"Covering pet stores, puppy mills, and animal profession, Earthlings includes footage obtained through the use of hidden cameras to chronicle the day-to-day practices of some of the largest industries in the world, all of which rely on animals. It draws parallels between racism, sexism, and speciesism." (source)
