我来补答
记得给分哈 Dear Editor
I read a piece of news recently.It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular.Why?--Fresh air is getting less and less in Japan,and so is it in the U.S.A.
In fact,environmental pollution is a very serious problem the whole world is facing.
it is mainly caused by the waste products released from artificial substances,industrial
production and increased consumption of goods.Bedsides,the use of chemical substances
in agriculture also causes environmental pollution.Look at the sky,you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.
How to change this condition?More and more countries are trying to work out some effective means to bring it under control,but no great success has been made.
