More Than Climate Change, Direct Human Action Predicted to Cause Fish Extinctions

September 13, 2008 By: Marshall Cutchin

“About four in 10 fresh water fish species in North America are in danger of extinction, according to a major study by US, Canadian and Mexican scientists.” (Tom Leonard in the U.K. Telegraph.) What do the scientists blame? Primarily overfishing, although climate change will be a big contributor to species declines. “‘Across the 21 different ecosystems we have looked at, direct human actions have long been exceeding – and will long continue to exceed – the effects of climate change in almost every case.'” (Article by Louise Gray.)
