A
Thirty years ago. Lake Ponkapog was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals and fish. The lake water is polluted. It is filled with strange plants.
How did this happen? First, we must think about how water gets into Ponkapog. When it rains,water comes into the lake from all around. In the past, there were forests all around Lake Ponkapog, so the rainwater was clean.
Now there are many homes around the lake. People often use chemicals in their gardens. They use other chemicals inside their houses for cleaning of killing insects(昆虫).
There are also many businesses.Businesses use chemicals in their-machines or shops. When it rains, the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake. So more bad chemicals go into the water this way.
People around the lake love their lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are careful about chemicals at home and at work. They must also be more careful about gas and oil and other chemicals on the ground, and they mustn't use motorboats any more on the lake. All these may change people's lives. Only then can Lake Ponkapog be a beautiful clean lake again.
