Coral Reefs

I just learn something really cool about coral reefs. That coral reefs are the only natural structure that you can see from space. Coral, that can range from so many different sizes, that when they are grouped together you can see them all from space. It goes on to make the point that every little thing counts because coral reefs are made up of just little coral but house the most complex ecosystem (in my opinion) in the world. They act like trees in the water and are just incredible and beautiful with all the different arrays of color, style, etc.
