Here is a petition to help halt the expansion of the TarSands project in Canada; it was recently named "The most Destructive Project on Earth"

A little known fact is that Canada has now surpassed Saudi Arabia as America's number one supplier of oil....Canada is becoming immensely rich from this, but it is coming at a terrible terrible cost to the present health of the environment, and is in danger of helping delay the needed transformation towards a low-carbon economy.

Please understand the scope of destruction happening right now...there is no comparison; the tarsands can be seen from Space.
