Why are the Tar Sands the world's dirtiest energy source?

[Overseas]

21. K&R. Tar sands should be a last resort not a quick buck venture.

These are even dirtier than our current petroleum drilling projects which are still too messy and wasteful.

Tar sands should be second to last resort. AFTER we have tried to economize and use existing oil much more efficiently.

Fracking is so very destructive it should be a last resort, not a rush project like it has been.

We should have already tried every bit of waste reduction technology and energy conservation technology we have before we take one step toward fracturing the shale under our country and in the oceans.

We should have tried to increase the efficiency of our use of regular petroleum and poured a trillion into alternative energy before we even begin with fracking to get natural gas.

It just isn't right that we waste so much of the old fossil fuels before we go disfiguring our land and using up our precious water to keep our wasteful lifestyle going.
