New Amazon threat? Deforestation from mining

Sprawling mining operations in Brazil have caused roughly 10 percent of all Amazon rainforest deforestation between 2005 and 2015 — much higher than previous estimates — says the first comprehensive study of mining deforestation in the iconic tropical rainforest. Surprisingly, the majority of mining deforestation (a full 90%) occurred outside the mining leases granted by Brazil’s government, the new study finds.
