You know, it's not just animal stuff. It's everything. In the last couple of weeks they had the Four Corners special on the sheep slaughter in Pakistan (I taped it, I haven't watched it yet), the Melbourne Cup which was shrouded in the knowledge of the violence of the horse racing industry, Uganda announced that they're going to start killing the homosexual people in their country, a woman in Ireland died because they refused to give her a lifesaving pregnancy termination... Every time I read the news it's more and more and more. Crap upon crap upon crap....
My number one piece of advice is to spam your social media with information. It helps you cope because you feel like you're contributing to making sure people know this stuff is going on. Even if you don't have many Facebook friends of twitter followers or whatever, someone might see and it makes you feel better.
Next piece of advice is find other ways to be proactive. Write letters to perpetrators or politicians, and attend protests with like-minded folk.
Don't be afraid to take a break if it's all getting way too much. A few days just doing fun things on the internet or in the world and not focussing on the bad stuff is important if it keeps you well.
Finally, I recently downloaded a game when you design a virus to kill all the people. Called Plague Inc on my iPad but I think you can get it for phones as well. It sounds a little twisted I suppose, but trying to kill everyone when you're mad at the world helps to alleviate some of that anger lol

or maybe I'm just sick and twisted! Hahahaha!
