Lush fighting Animal Testing

In 2012 lush launched this global campaign to get people to sign a petition against animal testing.

Im not necessarily going down the animal testing route, however for my practical work, I like the idea of a campaign. Something thats hard hitting and challenges public apathy.
I could base it around the cruelty toward farm animals. something that would perhaps make people consider eating meat a bit more, make people stop all together or maybe reduce their intake. It doesn't necessarily have to have the influence of global warming running throughout, as my essay will hold all of that information, but this could be the synthesis that I need.
