This last week an urge to protect Lake Erie against algae bloom was spread out in allnews across Canada and the US.

The excessive blooming of algae produces harmful toxins and contributes to oxygen-deprived “dead zones” where fish cannot survive.

They accounted for more than half of the phosphorus that reached the lake in 2011, while one-third came from smaller farms and nearshore communities as well as city sewers.
