When you're a movie star like Leo DiCaprio, you get to choose where and with whom you're going to do the Ice Bucket Challenge. Instead of a movie set, he did it in on a beach with a First Nations community. Instead of nominating his famous friends, he challenged some petroleum dudes and the prime minister of Canada. First Nations communities have been trying to stop the tar sands and the poisoning of their water. I wonder if Canada's prime minister, Stephen Harper, will take the Ice Bucket Challenge using *that* water?
