Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, 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 (污染的). It is in a colour of
dirty brown, and it is filled with strange plants.

How did this happen? First, we must think about how water
gets into Lake 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 (化学品) in their gardens. They use other chemicals
inside their housed for cleaning or killing insects (昆虫).
There are also many businesses. Businesses use chemicals in
their machines or shops. Other chemicals fall onto the ground
from cars or trucks. When it rains, the rainwater picks up all
the chemicals from homes and businesses and then carries them
into the lake. They pollute the water and kill the animals.
Boats on the lake are also a problem. Lake Ponkapog is a
popular place for motorboats. But oil and gas (油和汽) from boats
often get into the lake. So more bad chemicals go into the
water this way.
People in Hartwell are worried. They 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
