This is just showing the distribution of arid land and the deserts in different countries. This is also showing how these deserts, once rainforests, have rapidly changed into non-polar arid land.


I have researched and found that researchers have found underwater sand dunes in the Amazon forest and can be very soon turn into a desert. The forest cannot withstand more than two consecutive years of drought without breaking down. The study is made by the blue-chip Woods Hole Research Centre, carried out in Amazonia.
