In
our world today, there is a number of environmental issues that need to be
addressed. One of these issues is air pollution. Air pollution is caused by a
number of things, but one of the major causes can be traced to the byproduct of
combustion engines. The byproduct that is emitted is carbon monoxide. This
deadly gas is accumulating more and more in our environment and needs to be
contained in some way. One of the places that are affected in a very apparent
way is Hong Kong. The population of Hong Kong is very dense, which in turn
causes the need for cars and buses to rise. But because of all this gas being
put into the air, the sky is literally a hazy grey color all of the time. Now, not every place is just like Hong Kong in
terms of population. But in time, if we do not attempt to control our
emissions, the skies all over the globe will be that very same grey color, if
not worse. Island civilization can help
control this in that if we limit the space we use, the less need we will have
to use mechanical transportation. If your job office was within the island
boundaries, you may not have to drive there every morning; instead you could
take the electric train, or walk even.

I agree with you that air pollution is a very serious environmental issue and what it does lead to such as haze, carbon monoxide, and smog are very dangerous to human health and the environment. In my environmental issue which was deforestation, I mention that the more people cut down forests, the worse the air pollution is due to the fact that trees take in CO2 and other harmful air pollutants and convert them to clean, breathable, oxygen. Island Civilization can not only decrease the need to travel so far and use combustion engines, but they can also help save the forests that give off fresh air and decrease air pollution.
