‘Frightening’ findings foretell ills for ecosystems

“When it comes to determining the causes negatively affecting the biodiversity of our ecosystems, a new interdisciplinary study at Western is putting numbers behind the devastation. And it’s not good.

“The study’s lead author, recent PhD graduate Beth Hundey (Geography), showed, for the first time, that 70 per cent of nitrates in high mountain lakes in Utah are from human-caused sources – with fertilizers having, by far, the most impact at 60 per cent, along with another 10 per cent caused by fossil fuels. The research suggests these findings could apply to other mountain ranges in western North America.”   phys.org

GR:  Putting fine points on specific human impacts is truly important, but we also need to search for ways to pierce the polluters’ political armor. We need to act, and we need to do it now.
