exploitation of tar sand oil in Canada

Stop building a pipeline from Canada to prohibit our participation in the tar sand oil.

Why is this important?

If the Canadian tar sand is exploited for oil, together with our continued use of fossil energy, the carbon dioxide level in the air is expected to rise to a degree, compatible with levels 2.5 mill years ago, when the sea level was 50 feet higher that it is today. This outlook does qualify for a crisis for our grandchildren's survival and bodes very badly for our immediate future. We must urgently address our energy policies.
