US, Canada aim to cut Lake Erie phosphorus runoff by 40%

Concepts of Thinking: Interrelationships, Spatial Significance, Geographic Perspective

Inquiry: What might have caused the levels of phosphorus to get to levels that need to be reduced? How might Canada and the US agree to reduce the levels? What might some implications be if levels do not return to normal?

Activity: Conduct an issue analysis to help develop a potential solution to the problem. Map the extent to which the algae bloom has grown. Use water current data to determine future implications.
