In 2005 the caribbean lost half of its coral reefs through the process of bleaching, in 2010 off the coast of florida large amounts of cold water caused a majority of the coral in that area to bleach so badly that it ended up dying because it could not heal itself. Coral reefs are stressing out and going through a process called bleaching which causes them to lose all their color. The reefs are a big part of the world's ecosystem and if they die then the world will lose valuable money and resources they provide. Without a change to help destress the coral reefs then the coral will die. The bleaching process is where the relationship between the algae called Zooxanthellae and the coral itself becomes stressed from some change in their environment
