Toledo water crisis

2014-08-06_1146According to U.S. News on August 4, 2014,

Toledo, Ohio, just spent three days without water. It’s unlikely anyone in the town noticed. Five hundred thousand people couldn’t drink the water because an algae bloom in Lake Erie produced a toxin called microcystin. The toxin is so poisonous that that you couldn’t use Toledo’s water to bush your teeth or take a bath and it would kill your pit bull if you put it in his dish. You couldn’t boil the water because that would increase the concentration of the toxin. Exposure to microcystin results in abnormal liver function, diarrhea, vomiting, nausea, numbness, and dizziness.

Discuss how the cause algae bloom and how it is related to industrial agriculture practices.
