Earth with no tress

It is very scary to even think of our earth with no trees . Imagine what will happen to all the life forms if no trees exists on Earth ? What if all the greenery of our earth gets depleted or destroyed ? Every life forms on earth from a very simple bacteria to complex organism like humans , all of us require oxygen to stay alive . And we get this oxygen not other than the trees. if there are no trees ,there will be no oxygen and we will die. Also , trees are responsible for rainfall and for removing the toxic gases from the atmosphere . The survival of living organisms including humans will be threatened . And all the life forms on the earth will perish in the absence of trees . by ; sakshi first blog ever.........
