A Bison grazing on land reclaimed from a former tar sands mine at Syncrude Mildred Lake, north of Fort McMurray. The Alberta tar sands in Canada are the largest industrial project on the planet, and the world's most environmentally destructive. Syncrude are very proud of their reclaimed land, though only a tiny fraction of mine affected land has been reclaimed, and reclaimed into grassland rather than the species rich boreal forest that used to stand here. The Bison were introduced as part of a greenwashing project. When one was harvested, the meat was found to be so contaminated it had to be dealt with as toxic waste.
