What are some animals organizations from around the world that have good doentaries to watch?

Like factory farm videos, or videos of beautiful scenery or animals of all kinds. I am looking for international organizations with doentaries, videos or commercials not just north american. Or animal rescue videos etc...I want to contact these org's and see if i can use some of their videos to show other people. It's not to make money at all. For example: "Wildaid has some great commercials for animal preservation" or "The Meatrix" or "National Geographic online"
