Desertification

Desertification 
Desertification, is a very serious ecological and enviormental problem the Gobi desert is facing. By definition, desertification is a land degrading process that turns a relatively dry land region into an arid area with water, vegetation, and wildlife loss.The Gobi is now expanding into China's grassland and causing heavy damages to agriculture.

Desertification occurs because of multiple factors. Two major factors are climate change and human activity. Ironically, the changing of climate is partially the product of human activity. Deforestation, overgrazing, and depletion of water resources are some remarkable attributes to desertification. On the other hand, climate change "may exacerbate desertification through alteration of spatial and temporal patterns in temperature, rainfall, solar radiation and winds." As I stated earlier, human activity and climate change are interrelated. If no change is taking place, more inadequate human activity will intensify climate change which will subsequently further exacerbate desertification.
