What is drought?

A drought is defined as an extended period of abnormally dry weather that causes water shortages and crop damage. 



What caused the drought in Thailand?
The drought is caused by two main reasons one is caused by human and two is caused by nature. Human is the main causes that make the weather change by deforestation and development of industry that increasing more carbon dioxide in the air and carbon dioxide is a CFCs substance so if the air has more carbon dioxide it mean the earth is getting warmer because of the green house effect, and it also destroy the ozone layer that filtered the sun’s rays so the sun’s rays in the earth is increasing and it make the earth getting warmer too.
Even the main cause is human but the nature is also cause the drought in Thailand. Weather changes, the change of sea level are the example of the cause by nature. In Thailand another reason that cause the drought in Thailand are less south- west monsoon, and earlier north eastern monsoon that blow cold and dryness.
