BR12: Dessert

There is the biggest dessert in Riyadh, in Saudi Arabia all over the world. That is the Sahara desert.
Now dessert is going to spread all over the world, There are some reasons. People cut the trees too much, so CO2 doesn't absorb by trees, then it causes the grobal warming. In addition, the grobal warming causes desertification.
These things are said as the other reasons of desertification; slash-and-burn faeming, surplus population, too much pasturing, and cultivation. Of course climmate changing is one of the reasons.
There is even a treaty for the desertification.
To try not extend dessert anymore, people should live them lives with consideration about environmental. It is quite serious problem.
