Oil sands Youtube video full of misinformation but effective

The Calgary Herald notes that Angus Reid decided to survey 4,000 people in Canada, the U.S. and Britain about the oilsands using a video made by a number of U.S.-based environmental groups.
The problem is that the video itself, entitled
Rethink Alberta, is factually incorrect.
There's nothing wrong with using a video to illustrate a point, but when it contains bits of information such as the oilsands destroying an area the size of England and that there are 17,000 hectares of contaminated tailings ponds -- big enough to be seen from outer space -- a line has been crossed.
The appropriate representation goes more along these lines: in 40 years of mining, 620 square kilometres have been disturbed, which is equal to less than five per cent of Los Angeles County.
