Deforestation Is Making Fish Weak and Skinny

The loss of trees could eventually spell trouble for the human food chain, say researchers.

Humans mistreating the forest might not immediately suggest collateral damage in the aquatic realm. But the link is there, according to researchers who allege deforestation is making fish thin and puny.

To establish a harmful connection – and one that could potentially come around to damage our own food resources – scientists at the University of Cambridge trekked across the ocean to Ontario's Daisy Lake, located on the edge of the historical mining city of Sudbury. They chose this body of water due to an ecological disaster it suffered in the mid-1900s; the nickel-smelting industry produced acid rain that withered and literally blackened the landscape. Today, there are areas of Daisy Lake's shoreline where the trees have grown back, and other parts where the vegetation is still patchy and poor-looking.
