Coal-burning is a major source of pollution and greenhouse gases, specifically carbon dioxide and mercury, which threatens wildlife, like bald eagles and penguins. This makes coal a prime target for environmental groups.

Greenpeace, which exists in 40 countries worldwide, doesn’t like coal. In fact, just last month activists dumped 4 tons of coal in front of a Sheraton hotel in Warsaw, Poland to protest against carbon emissions. And that wasn’t the first time they’ve done it.

Previous coal drops include the home of Vice-President Dick Cheney, former British Prime Minister Tony Blair’s Downing Street offices, the Philippines Environment Ministry and Nuon’s headquarters in Amsterdam.

So, word to the wise, don’t tick off Greenpeace! Otherwise you’ll be knee-deep in dirty black stuff.
