Space satellites for saving the forests. Why not?

There are many ways to save the forests: cleaning, volunteering to grow new trees and many-many more. Seems like scientists have found a new one - observing forests from satellites in space. What a great idea, don't you think?  Now they'll be available to use these radio waves to calculate the forest biomass and tomographic radar to measure the layers of the forest to better understand how trees are distributed. It's a quiet important discovery because it opens a new door and makes us closer to saving tropical forests in such countries as Brazil and Indonesia. Learn more here.
