The proposed Pebble Mine in Alaska's Bristol Bay wilderness may be the worst corporate assault on America’s natural heritage that no one’s ever heard of.

Bristol Bay's untamed wilderness is home to the greatest wild sockeye salmon runs on the planet, an astounding diversity of wildlife, and a way of life for Native communities that have thrived there for thousands of years.

But a Canadian mining company wants to carve a gargantuan open-pit, gold and copper mine out of the heart of this American Eden. 

The Environmental Protection Agency has confirmed that the Pebble Mine carries catastrophic risk for Bristol Bay. But despite the warnings, Canada's Northern Dynasty Minerals is recklessly pushing ahead with this $6 billion mega-mine.

Send an urgent message to Northern Dynasty's president telling him to abandon plans for the disastrous Pebble Mine.

NRDC has been fighting to block the Pebble Mine for years. And thanks to people like you, we've been able to help pressure two global mining giants to withdraw their support for it. Northern Dynasty Minerals is the last holdout. They can be stopped, but only with your help.
