Re: “Lake Erie: Algae Blooms Ensure Ongoing Threat”
The algae blooms are from nutrients (fertilizer) being washed off fields and out of sewage plants into the streams and rivers by the rain. The nutrients feed the algae and the algae bloom grows bigger and bigger. The algae eventually dies and rots, stripping oxygen from the water during decomposition to make carbon dioxide. Fish are killed by the lack of dissolved oxygen in the water.
