If you're unaware of the common practices in dairy production I highly recommend you watch this video. Millions of animals experience this life on a daily basis. It's five minutes. Press play.
Below are two videos (part 1 & 2) of a new documentary about meat production and the cost to our planet. The audio isn't that great but the video itself is quite good.
Here's another video from the Hillside Animal Sanctuary which has a sad but positive ending. It's a very difficult video but does end happilyfor some animals. Also, please don't think these videos are one-off situations.
I'm sorry to keep posting these videos but they are reality. This video, from The Hillside Animal Sanctuary shows real footage of factory farming conditions in the UK. Please be aware there are graphic images of dead and dying animals in this film.
