As a result, they are no longer pleasant or safe to use. Pollution is bad for animals and plants, and it
even makes people"s health in danger. In our daily life, we can see different kinds of pollution in many
places. There are three main forms of pollution: land pollution, air pollution and water pollution.
Land pollution is caused by solid waste, such as cans, bottles and some plastic things which aren"t
broken down quickly. It makes the environment look very bad. However, air pollution is more serious
than land pollution. It is much worse in cities and towns because of the fumes (废气) from traffic and
the waste from human(人类的) activities. When people drive their cars, fumes which are most made
up of CO2, NO2 and SO2 are given off. After the gases get into the air, they may mix with clouds.
Then they will become some harmful chemicals falling on the ground with rain. It is one of the reasons
for soil erosion (土壤侵蚀) which is one example of water pollution.
Various kinds of pollution will cause many health problems. People have realized they must change
this serious situation. There are many ways to control pollution. To develop alternative energy (替代能
源)is very popular in many countries. China, for example, has made up its mind to be a leader in this field.
It is trying hard to make full use of energy from the sun and wind. It has paid plenty of money to make
electric cars and trains instead of traditional traffic. We should also take action to make our environment
cleaner every day. Take cloth bags while going shopping and drive cars less. We have only one earth.
We must take small steps now to help protect our environment for the future wherever we are.
