Greenpeace is not happy with Mark Zuckerberg, who is known as the maker of Facebook. Facebook uses a lot of servers in data centers, and therefore a lot of electrcity. The problem Greenpeace has is that Facebook runs on servers powered by electricity generated mostly (58%) from the burning of coal.

The video Greenpeace released attempts to send the message that Facebook needs to change its energy practices or it will lose all its friends. Although that’s far from the case, 600,000 Facebook users joined a group on the social network asking them to Unfriend Coal.
