The most serious environmental problem
Sample one

• There are many big problems facing the
  earth. In my opinion, pollution is the most
  serious one.

4

• The whole industry produce a lot of waste
  products that destroy the environmental balance.
  Many products are bad for the environment. For
  example, drinks are increasingly sold in bottles
  or tins which can not be reused. Plastic bags are
  used

5

• everywhere. Whats more, rubbish is dumped on
  the side of streets, which let out bad smell.
  This not only causes problems, but also waste
  resources, such as glass, metals, paper and tins
  and so on. Id like to advise people not to buy
  products that harm the

6

• environment. Pollution and waste combing to be
  a problem. Everyone can help to solve these
  problems by cutting out unnecessary buying and
  careful use of the products we have in our daily
  life. Besides, people should plant trees and
  flowers to protect nature.

Sample two
Water Pollution

• Water pollution is caused by waste from
  factories and cities. Oceans are able to clean
  themselves, but certain seas, once they become
  dirty, they are not able to do so. One example is
  the

8

• Mediterranean which lies between Europe and
  Africa. It has only one narrow entrance to the
  ocean in the west. One quarter of the shores of
  the Mediterranean are polluted and are on longer
  safe for swimming, as a lot

9

• of diseases are present in the water. In most
  places it is not safe to eat the fish.
• Lakes also have the same problems. Lake
  Baikal in Asia was once the cleanest in the
  world, with over 700 different kinds of plants

10

• and animals. Now, however, the waters of this
  great lake, which is also the worlds deepest
  (over 1,740 meters), have dirtied by waste from a
  chemical factory.

Sample three
Earth Problem

• The desert in the world is growing every
  year. Many parts of the world, which once had
  large populations and plenty of crops, have
  become deserts. Dunhuang in China, deep in the
  heart of the Gebi Desert, was once a great city.

12

• Cattle are one cause of the problem. In
  good years, farmers increase the numbers of their
  cattle. Then one year later, the rain fails to
  come. The farmers do not want to kill any of
  their cattle, so the cattle eat all the grass and
  anything that grows on

13

• poorer land. If this continues for several
  years, the grass never grows again and the land
  becomes a desert.
• One suggested answer for farmers is to
  limit the numbers of their cattle.

14

• Another problem is that good soil is
  gradually lost. When trees are cut down, there is
  nothing to hold the soil in place on the
  hillside. So when it rains, the soil is washed
  down the hills. Strong winds can also blow away
  the valuable soil that lies on the top of the
  field.
