DUST BOWL

American state of Oklahoma suffered severe drought situation in 1930s. there was no crop due to lack of rain and the fields had dried to the extent that the soil blew away as dust and created what was called a 'DUST BOWL' region. People had to leave that area for further survival. A similar drought situation development took place in the state of Illinois in July 1988 when the then President Ronald Reagan during his visit to the state told farmers :"This is the worst natural disaster since the Dust Bowl of 1930s."

A NASA scientist in his report to a committee of the US Congress had told that "DUST BOWL DROUGHT" was 99 per cent certain to be caused by pollution of air and that it was an early sign of a dangerous climatic change, a change which leads to a general warming of the global atmosphere. This, in turn, affects the rainfall, as well as having other side effects. He said this atmospheric pollution was the "GREENHOUSE EFFECT". Thus 'DUST BOWL' was blamed on the Greenhouse Effect.
