A coalition of environmental groups said Monday it is withdrawing a lawsuit against a renewable energy giant that it has accused of jeopardizing the last remaining wild Atlantic salmon in the U.S. The groups sued Brookfield Renewable, claiming the company kills salmon on the Kennebec River with its dams. Atlantic salmon only return to a handful of U.S. rivers, all in Maine, and they are protected under the Endangered Species Act. The conservationists were dealt a setback last month when the federal government ruled the salmon can coexist with hydroelectric dams on the Kennebec, as long as upgrades are eventually made to allow salmon to pass through the dams more easily. >click to read< 12:15
