Since the early days of Google Earth, organizations have found it to be an excellent tool for tracking the status of coral reefs. Back in 2006, Frank showed you ReefBase and Reef Watch, and we’ve posted a variety of other stories since then. Coral Reefs cover less than 0.1% of the ocean, yet nearly 25% of all known marine species call them home, making them crucial for our oceans ecosystem.
The World Resources Institute has used Google Earth to create tours of reefs around the world to show threats them from sources such as coastal development, pollution, climate-related threats and others.

Their tours include photos and underwater video from reefs around the world. Taking it further, they also have created maps to show projected reef maps for the years 2030 and 2050. You can download this KMZ file
