At the southernmost tip of South America, the towering Andes rise sharply from the deep waters of the Pacific, creating a rugged expanse of coastal islands, dense rainforests and snow-capped glaciers. Thanks to years of advocacy by NRDC and our local partners, hydroelectric company HidroAysén has suspended its plans to build five mega-dams on two of Patagonia's pristine rivers that could lay waste to one of the world's last unspoiled regions and flood thousands of acres of wildlife habitat. But the company has not ruled out resuming work on the project in the future. NRDC is continuing our fight to end to this massive industrial complex once and for all.
