Topic:Some people believe that the Earth is being harmed (damaged) by human activity. Others feel
that human activity makes the Earth a better place to live. What is your opinion? Use specific
reasons and examples to support your answer.

People have been living on the Earth for thousands of years. Human activity influences the Earth.
Some people believe that the Earth is being harmed by human activity. Others feel that human
activity makes the Earth a better place to live. In my opinion, the earth is being damaged by
human activity. There are many statements supporting my opinion.

Human activity has damaged natural environment and almost exausted natural resources. Modern
industry needs more and more resources, including minerals, fuels and water. So we confront of
the serious problems such as the lack of fuels and water. Ecological balance is damaged because
factories occupy many places where animals and plants live. More and more buildings are
constructed and forests become less and less. If we cannot recognize these problems and solve
them soon, we would finally lose the environment suitable for our living.

An other serious problem is “the green-house effect.” Human activity decreases forests and
increases the usage of fuels so that the gas of carbon dioxide is output more and more and there
are not enough plants to absorb it. The green-house effect is more obvious and more sensible
these years. Due to the effect, icebergs in the south polar and north polar melt and the sea level
becomes higher than before. I am worried about the cities nearby the sea and hope scientists find
an effective method to eliminate the green-house effect.

Although we have advanced machines and our life seems more comfortable than before, we have
less chances to approach natures and less spaces to act. The cities become bigger and if we want
to have a picnic with our friends, we have to drive a long distance to find a natural place. In fact,
the spaces of human activity are being damaged by the skyscrapers and factories.

From the above statements, we can conclude that human activity brings the Earth many damages.
Fortunately people have recognized the point and I believe that the Earth will become a better
place to live with our ceaseless efforts.
