Deforestation


More than 80 percent of the Earth’s natural forests already have been destroyed.

Among the obvious consequences of deforestation is the loss of living space. Seventy percent of the Earth’s land animals and plants reside in forests.

Deforestation may have catastrophic global effects as well. Trees are natural consumers of carbon dioxide—one of the greenhouse gases whose buildup in the atmosphere contributes to global warming. Destruction of trees not only removes these “carbon sinks,” but tree burning and decomposition pump into the atmosphere even more carbon dioxide, along with methane, another major greenhouse gas.

It's a very interesting post! As we can see the deforestation could be a big problem if we don't do something now.

Happy Birthday :)

Forests are Earth's lungs, we should take care of them, not destroy them!
