The price of gold and the loss of forests

“Everything is connected” is something we say so often in ecology that it often loses its meaning. However, this new study published today in the Proceedings of the National Academy of Sciences really exemplifies the real world impact of these connections.

Skyrocketing gold prices, driven mainly by speculators, has spurred an epidemic of illegal mining (and consequently deforestation) in the Peruvian Amazon. These mines are dangerously close to a major river system, increasing the risk of mining pollution entering the Madre de Dios River watershed. Mining and deforestation often go together, as we know very well here in the UP.

Greg Asner and his colleagues used remote sensing imagery to detect these mines and measure deforestation caused by them. The images themselves provide a powerful message. Each hectare lost to mining can support hundreds of tree species, and thousands of animal species which depend upon them. The loss of these forests and risks of pollution are difficult to calculate, and therefore difficult to balance against the fluctuating value of the gold retrieved from the mines.

UP Landscapes exhibit at the Beaumier Center at NMU

A new art exhibit, “U.P. Mosaic: A Working Landscape and its People” will open this month on the Northern Michigan University campus. Although the information is not yet up on the Beaumier Upper Peninsula Heritage Center‘s webpage, you can find details about the events on opening day (October 26th) through the Marquette Monthly magazine. The exhibit will run from October 26 through January 15, 2014, and will be open 10am to 4pm Monday through Saturday.
