The exact number is unkown ( realy diffucult to calculate it ) but we got some information about that:
The World have 9.5 Bilion acres of tree land (FAO Forest Resources Assessment 2010). And trees cover %29.5 percent of Earth Surface.
Everyday we are loosing 2740 hectars Tree Land :/ . And every second we are loosing 0.76 Hectar Tree Land :/ . The total number of trees in the world ; if we calculate it 4 Trillion 967 Bilion Tree we have. We need to save it fast.
Because if we won’t save the tree we will lose All trees in 700 years. And the world will be without any trees.
Let’s share this information with another guys and we can try to save the world. Because the ending of the World is not so much far, if we countinue to loss the Trees on World.
