Lake Erie is a global treasure. And right now it’s under threat.

Every summer, runoff pollution from urban and agricultural lands is causing algae in Lake Erie to grow out of control, impacting the health of the lake and turning its waters a nasty shade of green. These algae blooms can suffocate fish, make water unsafe for drinking and swimming, keep tourists away, and put a dent in local economies.

We must act to reduce the amount of runoff pollution entering the lake. Together, we can help keep Lake Erie clean and not green.
