The tar-sands project in Alberta is an environmental disaster, destroying vast swathes of forest lands obliteration of a massive ecosystem. The volume of toxins used to turn this sludge into usable oil is an environmental disaster on its own. Then there is the insanity of pumping this black death across America through towns villages and farmland. Already there has been spillages that have devastated towns and agriculture. Once again it is corporate greed riding roughshod over the people, all to fatten shareholders bank accounts. It is the world's largest environmental degradation, all for money.
