Here is just one example:
Oil floats on the surface of an unlined tailings pond (containing waste water from tar sands processing) north of Fort McMurray, Alberta Canada.
The Alberta tar sands produce 475 million gallons of toxic waste a day (about nine times more than the amount of oil produced each day). It is estimated that the tailings ponds, which are unlined, leak nearly 3 million gallons a day. The tailings ponds kill thousands of birds (mainly ducks and waders) a year when they land on the tailings ponds, mistaking them for one of the areas many lakes.
