The Devastating Costs of the Amazon Gold Rush
The destruction is more absolute than that caused by ranching or logging, which accounts, at least for now, for vastly more rainforest loss. Not only are gold miners burning the forest, they are stripping away the surface of the earth, perhaps 50 feet down. At the same time, miners are contaminating rivers and streams, as mercury, used in separating gold, leaches into the watershed. Ultimately, the potent toxin, taken up by fish, enters the food chain.
...
At first light, workers hefting huge Stihl chain saws roar into action, cutting down trees that may be 1,200 years old. Red macaws and brilliant-feathered toucans take off, heading deeper into the rainforest. The chain saw crews also set fires, making way for more pits.
This gaping cavity is one of thousands being gouged today in the state of Madre de Dios at the base of the Andes—a region that is among the most biodiverse and, until recently, pristine environments in the world. All told, the Amazon River basin holds perhaps a quarter of the world’s terrestrial species; its trees are the engine of perhaps 15 percent of photosynthesis occurring on landmasses; and countless species, including plants and insects, have yet to be identified.
...
The most recent data show that the rate of deforestation has increased sixfold from 2003 to 2009.

Lovely.
Another consequence of the global economic mess.
*sigh*
I guess in the end, this demonstrates we will likely not overcome our tendency to destroy what is required for our survivability.
Oh, don't get me wrong... Life will continue...just with a whole lot fewer of us (if any) to witness the 'new' normal.
