Task 1

As civilization develops, engineering has never failed to prove its contribution in making the Earth a better place to live in. For the past century, engineering has shown great achievements in various fields be it agriculture, automobile, construction or service sectors. These innovations have certainly enhanced humans’ standard of living.


In this modern civilization, growth of populations and demand of a better lifestyle have brought much challenges to the engineers. Standard of living has risen tremendously causing more people to use private cars rather than public transportations. This eventually causes the green house effect to take place due to the large emission of carbon dioxide. Rapid growth of population causes insufficient clean water. Other than these, imbalance nitrogen cycles in the atmosphere have also given a big challenge to engineers.


Among all these challenges mentioned above, having to control the excessive amount of carbon dioxide in the atmosphere is seen as the most important idea. Carbon dioxide, like glass, traps sunlight without allowing it to be re-radiated as heat from the atmosphere, eventually heating up the Earth. This process contributes to global warming.


Global warming causes rise in average global temperatures which eventually cause a lot of problems to surface. Sea levels will rise resulting in the evacuation of coastal population. Agriculture will also be affected as plantations cannot withstand drastic change of climate brought about by the global warming. Most alarmingly, the ecosystem will also be affected. Species will become extinct due to the inability to adapt with climate change. According to a new study on massive species extinctions due to global warming which is published in the scientific journal Conservatory Biology, “ A quarter of the world’s species would be committed to extinction by 2050 as a result of global warming”(Conservation International, 2006). It is clear that global warming is disastrous.


The main factor of global warming, which is the excessive amount of carbon dioxide, must be controlled and reduced to a safe amount. It is not easy to capture the carbon dioxide produced in the combustion of fossil fuels and store it in a safe place, away from the atmosphere. This process which is called carbon sequestration must be economic, safe and efficient. Finally, it is most crucial to the engineering profession to design an ideal carbon sequestration method so that the tranquility of all the living organisms is insured.

cghello. nicely written essay about the importance of controlling the amount of carbon dioxide in our atmosphere. global warming is a major problem in this era of massive industrialization. not very complicated and ideas are arranged in a proper manner. anyway, should add in more words like however, moreover and therefore so your essay has the flow and each paragraph is related. all in all, good first piece of work!

Hello...
A good essay with clear contents and ideas. It is also supported by elaboration and facts.
The idea is obviously stated in each paragraph.

Hi, I would say that it's really a very good piece of work with clear ideas well organized in paragraphs. However, personally I think that maybe you can try to use present continuous tense in paragraph four instead of the future tense as the effects are actually happening in our world now.
