Last year De Beers opened a diamond mine in the Canadian Tundra, draining an entire lake while killing nearly twenty thousand fish according to the Wall Street Journal:

That's a lot of fish that De Beers "donated" to the local community -- in one big batch!  (There's obviously no further fish to eat from that lake.)

In addition to a lot of dead fish, aboriginal groups are finding the mine’s environmental review to not address concerns about water quality or the future of the lake after it was drained for mining.

 

Far around the world, in Southwestern Namibia, 10,000 square miles of pristine, untouched beach - nearly 3% of the entire country - has been known as the Forbidden Area. The region was cordoned off from the public in 1908 when “sea diamonds” were found being washed ashore. 

Today, “a dozen miles off the southwestern edge of Africa’s Atlantic coast, a 285-ton vacuum machine operating 400 feet below sea level is sucking some of the world’s most valuable diamonds from the ocean floor,” reports the Wall Street Journal. According to Emily Jeffers, a staff attorney for the Center for Biological Diversity, this kind of deep sea trawling and digging has unexplored effects on the ecosystem.
