If I told you that Earth is greener than expected ... Would you believe me? I'm not talking about a dream of a girl who loves nature because it is the truth. A recent study done by an international team of scientists from the Yale University showed that there are about three billion of trees on Earth, which is a number seven times higher than the previous estimates and above all the expectations (you'd never guess it, right?).
Until recently, to know how many trees there were on Earth people used satellite images that were unable to provide numerical reports. For this reason scientists decided to make a global census, through 430,000 reliefs, on every continent except Antarctica. This analysis shows that the tropics and subtropics areas are the richest of trees. Then there are boreal and temperate areas. At the same time we must remember that the presence of man is so evident on the green lungs of the earth: every year 15 billion of trees have been cut and since the beginning of civilization, there was a loss of 46% of the original vegetation.
Treedom plants trees… did you already know this? :)
