What's Happening to the Great Barrier Reef?

The Great Barrier Reef is located near the Queensland's coast and is the biggest coral reef in the world.The Great Barrier Reef is also being threatened by tourism, boats leaking oil and boats dropping their anchors and drag along the reef.
I think this is a big problem, because this is a very big tourist attraction.
I did also read at the internet that in about year 2500 it will only be 5% left of the reef.
We how to do something about it!
