This Oct. 5, 2011 satellite photo from a NASA website shows algae blooms swirling on Lake Erie. A study released Monday, April 1, 2013 said the warming climate and modern farming practices are creating ideal conditions for gigantic algae formations on Lake Erie. The shallowest and southernmost of the Great Lakes, Erie contains just 2 percent of their combined waters but about half their fish. (AP Photo/NASA)
