I must confess, I don't watch MTV... I'm not the target demographic. But I do visit the Compassion Over Killing website occasionally and noticed that they are starting up their MTV advertising campaign again. They've been running pro-vegetarian commercials since 2004. Personally, this year's ad isn't my favorite, but I applaud their efforts. It will certainly wake up a few people to the horrors of meat production, and they're targeting the right audience.
If you're new to veganism, or considering it and haven't seen the Earthlings documentary, narrated by Joaquin Phoenix, we highly recommend it. Out of all the things we've read and seen, that documentary is the reason Jane and I can never consider going back to eating meat.
