Top 10 TED Talks Number 4 (again, in no particular order): Garth Lenz tells us about the dirtiest oil in the world - the Alberta Tar Sands. Lenz begins by extolling the beauty and value of the ecosystems that are being carelessly turned over to get at the oil rich sand fields underneath, to give context to what is happening.
The Tar Sands of Canada are a very difficult subject, because while they produce the dirtiest, highest carbon fuel in the world, they are also the economic salvation of the Alberta Province, and currently one of the primary economic engines of the Canadian economy as a whole. Before these Tar Sands were being exploited, Canada was one of the most progressive countries in the nation when it came to environmental issues, today it is one of the least.
Lenz is passionate and articulate, and his story is both personal and global - a difficult balance that he handles deftly. This video is also rather timely, as the issue of the Keystone pipeline is once again up for grabs in the next election.
