Narrated by Joaquin Phoenix, and with music from Moby, this film has caught the attention of the entire World. It depicts our relationship with animals, and how we depend on them for pets, food, clothing, entertainment and for scientific research and experimentation. Whilst we use them for all of these reasons, we tend to show a lack of care and respect towards other living beings, and the truth of our cruel treatment is exposed within this film. Factory farming, a prime example of this mistreatment by the human race, features heavily.
