threatens the health of the people who live in cities. City wastes cause water pollution when
they are poured into the waterways. These wastes kill fish and make some areas unfit for
swimming. In addition, many large cities have difficulties in disposing of their garbage. The
amount of garbage grows each year, but places to put it are quickly filling up. Citizens,
governments, industries, scientists, and business people must work together in different ways
to gradually reduce pollution. For example, most cities have introduced recycling programmes. Statements T F

Saving the Environment: One Home at a Time Giaoandethitienganh.info
Pollution can be seen not only throughout the world, but also in our own homes. It comes
from household chemicals, the amount of water people use and the waste people produce
and throw away. What can be done to stop this pollution? Surprisingly, a person can help
save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling
can also reduce the number of trees cut down to produce paper products. It takes very little
effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.
Second, we need to control the amount of water used at home. It can be conserved by taking
short showers instead of baths, repairing leaky faucets, using the dishwasher orwashing
machine only when fully loaded, or simply turning the faucet off while brushing your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but should also try to
use this waste effectively. For example, grass clippings and food scraps can be made into
compost for plants. The average person produces 4.3 pounds of waste every day, but we can
reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more polluted.
