It’s an interconnected world. Lake Erie is getting hammered by phosphorus, leading to toxic algae

so vast that in 2011 it covered a sixth of its waters, contributing to an expanding dead zone on its bottom, reducing fish populations, fouling beaches and crippling a tourism industry that generates more than $10 billion in revenue annually.

The phosphorus is comming largely from agricultural fertilizers in Ohio, washed by rains into the Lake Erie watershed. Solutions? Minimize fertilizer use. Clean up urban stormwater. Stop paving everything.
