Task1: Thick Cloud of Pollution Covering Southern Asia

Script

A United Nations study says that a thick cloud of pollution covering southern Asia threatens the lives of millions of people. Scientists say the pollution could increase lung disease and cause early deaths. The cloud is also damaging agriculture and affecting rainfall levels. It has affected 1 many countries in southern Asia. The pollution cloud is three kilometers high. Scientists say it can move halfway 2 around the world in a week.

The cloud is the result of forest fires, the burning of agricultural waste, and huge increases in the burning of fuels by vehicles, industries and power stations.

Pollution from millions of bad cooking stoves hs made the problem worse. Many poor people burn of fuels wood and animal waste in such stoves.

Scientists say this combination could be changing winter rainfall levels in Asia. They say rainfall has increased over the eastern coast of Asia. But it has dropped sharply 3 over parts of northwestern Asia. The report says the cloud could reduce rainfall over northwestern Pakistan, Afghanistan, and western China by up to forty percent.

Harmful chemicals from the cloud are mixing with rainfall. This acid rain damages crops and trees and threatens public health. Scientists are concerned that the pollution will intensify 4 during the next thirty years as the population of Asia increase to an Estimated 5,000 million people.
