The health of Lake Superior is facing a serious threat from pollution and runoff caused by development along its shores, according to a panel of scientists.
"Development along the shores of Lake Superior could be the greatest threat to the lake, scientists said during a conference in Duluth."
"The panel of scientists who spoke Monday agreed that pollution, rising temperatures and invasive species also threaten the world's largest freshwater lake and its cold, sensitive ecosystem."
"But several scientists said the lake is still in generally good health."
"The potential for more runoff, erosion and destruction of habitat will increase as more people develop and occupy the lake's shores, said fisheries biologist Mark Ebener."
