Environmental issue between the US and Canada?

I am doing my Social Studies assignment, and I have done all of the other questions but I am stuck on this one question:



"Choose an environmental issue facing both the United States and Canada. Explain how the countries have worked together to solve this problem."



If anyone can help me, that would be great. Thanks!

**I will give best answer**Environmental issue between the US and Canada?You could discuss 'trans-border environmental issues'. This includes Great Lakes Water Quality Agreement and Air Quality Agreement. Keeping the industrial heartland of the States and Canada free of pollutants. With all the industry the Great Lakes have become quite polluted as has the air with breathe. There is a lot of information on this. Here a few links to get you started.
