Read the passage and answer the questions.
Land pollution is another term for soil contamination (for example, by factory chemicals or sewage
and other wastewater). It means any kind of long- term land damage, destruction, degradation or loss.
Air and water pollution disappear, but land pollution doesn’t. It stays exactly where it is. Radiation
can contaminate land for thousands of years. That means radioactive waste dumps remain that way

indefinitely.


The biggest problem comes when contaminated land returned to use as buildings or agriculture land.
People might get their water from rivers. Diseases might happen over years for this reason.
We should try to find a way of stopping or reducing land pollution. We should recycle old things to
reduce our need for new ones. Also, we need to clean up many contaminated sites.

Read the passage carefully, then decide whether the following statement are true or false.
Every day on radio, on TV, and in the newspapers, we hear, see, or read about many problems in the
world, for example, pollution problems.
Air pollution is the first kind. It mostly comes from released from motorbikes, cars, airplanes, trains, and
poisonous gases emitted from factories. Also, waste is dumped anywhere, even in the city where many

people are living.
The second pollution problem is sea pollution. Many people earn their living from fish in the sea, and
the fish they catch feed many people. But the sea has become so polluted from oil spills, and factory
wastes that the fish are dying. This pollution is not only killing the fish, but is also affecting those people
who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more difficult
every day. We must find a good solution that makes the world a better place to live.
