Cary Brunswick’s article July 10 dealing with the Alberta tar sand is right on the mark.
As a geologist I have been aware of the “gunk” tar in Alberta for years, but I never thought humanity would be stupid enough to actually try to use it — wrong again!
We must demand that President Obama stop it with letters and phone calls to him. The main winners will be the oil companies — not us humans.
