▶ Your Answer :
Global warming is happening right now, melting
the icebergs at poles and taking away home of people living on islands. In order
to save the earth, there are many things that are needed to be done immediately.
Among many, I choose using renewable energy sources, taking public transportation
and using plastic bags as alternatives to improve the environment for the following
reasons: it improves air pollution and marine ecosystem.
First of all, using renewable energy
sources lessens air pollution. When using the renewable energy sources, the CO2
emission is ‘zero’, while other energy sources such as coal, oil, or even nuclear
energy produce carbon dioxide. It is obvious that there is a huge difference between
not producing harmful gas at all and producing harmful gas. Taking public transportation
reduces methane gas coming from vehicles. One car is reserved by one person,
while 20 people can go in one bus and 50 people in one section of subway. It is
an undeniable fact that the number of vehicles greatly affects the amount of
power source and pollution.
Moreover, using paper bags instead of
plastic bags can be a big help to marine ecosystem. Despite the convenience of
using plastic bags, it is a tough problem to handle the plastic. When burning
plastic, dioxide, which is graded as the most harmful particle, is produced. Therefore
most companies and countries throw away the waste at sea, causing water pollution.
There is a famous picture of a turtle bleeding with a plastic straw stuck to its
nostril. Also, when opening up the stomach of dead whale, about 80 percent of
the stomach is filled with plastic waste. When using paper bags, since it is
degradable, it will positively solve out this problem.
In conclusion, I firmly believe that utilizing
renewable energy, riding public transportation and choosing paper bags will benefit
the earth for the reasons I have mentioned above. All in all, efforts, as
little as using paper bags instead of plastic bags, can save the world and our
planet. |
