 Desert formation  沙漠的形成(3)

  Four specific activities have been indentified as major contributors to the desertification processes overcultivation, overgazing firewood gathering, and overirrigation. The cultivation of crops has expanded into progressively drier regions as population densities have grown.

 The Origins Of Cetaceans 鯨類動物起源 譯文
