Does human harmed the Earth or make it a better place to live?
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. Which ones are right? After pondering it from
several aspects, personally, I totally agree that the Earth is being
harmed by human activity.
From wood to iron, from coal to petroleum, human need more and
more resource to support their development. Our planet gives us
everything we need, but natural resource is not endless. People
deforest grown trees without planting young trees. Soon more and
more forests are deforested and gradually turn into desert.
The population increases quickly. There are more people than ever,
living longer than ever. For example, today there are over ten million
people in a big city. What a tremendous number! To feed millions of
people, more fields are needed. To hold the growing population,
cities extend a lot. Large population makes the Earth overburden.
Human activity also produces a lot of pollution. Factories dump
waste to into water. Also more and more exhaust air is given out.
White pollution can be found everywhere. Noise can be heard here
and there. What a bad condition! All of these must harm the Earth.
From all we discussed above, we can see that human activity really
harm the Earth. We must take action to heal the Earth, for our home,
for you and me.
