Executive order should help cut down on dangerous algae blooms on Lake Erie

This satellite image provided by NOAA shows the algae bloom on Lake Erie in 2011 which according to NOAA was the worst in decades. The algae growth is fed by phosphorus mainly from farm fertilizer runoff and sewage treatment plants, leaving behind toxins that have contributed to oxygen-deprived dead zones where fish can't survive. The toxins can kill animals and sicken humans.

TOLEDO, Ohio (AP) Ohio Gov. John Kusch has signed an order that sets out to create new regulations on farms and cut the amount of fertilizer feeding Lake Eire's huge algae blooms.
The executive order signed by Kusch on Wednesday comes after the state has said voluntary steps farmers have taken to scale back fertilizer runoff aren't working fast enough.
Ohio, along with Michigan and the Canadian province of Ontario, have pledged to significantly cut how much phosphorus enters the lake by 2025.
The new rules would force an estimated 7,000 farms across 2 million acres in northwestern Ohio to reduce the fertilizer and manure that flows into streams.
Farm groups have been pushing back against calls for increased regulations, saying it's not clear what approach will solve the algae problem.
