In August 2007, a group of nineteen young environmentalists set out by bike from Alberta's southern boundary to learn the truth about the tar sands and what they mean for people and the environment. As members of the Sierra Youth Coalition, coming from all across Canada, they were passionate about the chance to see things for themselves. They knew that the tar sands are the biggest obstacle to Canada meeting the terms of the Kyoto Protocol. They wanted to better understand why developing this resource is so important and appealing not just to oil companies but to ordinary Canadians as well.
