Canada Oil Sands
Where are they located?
The oil sands produce a lot of damage to Canada's environment. The oil leaks on to bodies of waters called tailing ponds, and when birds land in those bodies of water, they also get covered in oil. This makes it hard for them to fly, and cleaning them is a long process.
These tailing ponds are filled with arsenic and mercury, and when they leak, they go into our drinking water as well. Therefore this is a health concern, and environmental damage.
