Your essay showed that you indeed had knowledge on global warming.
But I felt that you could have talked about the negative effects of global warming before going on to talk about reasons for global warming and measures to be taken to counter to global warming.
Global warming is a serious problem for coming generation.
Explain why is it a serious problem.
I thought the reasons you have stated were good. But you could have linked some together:
There is a number of reasons behind the changing climate. Namely the over-exploitation of natural resources such as petroluem for the increasing number of vehicles on the roads; deforestation to meet the demands of the ever-rising human population. Such activities increases the concentration of greenhouse gases in the atmosphere, thereby increasing the global temperature..
Furthermore, industries wastage of acids and chemicals is very harmful for water creatures as well as human and environment.
If your topic is Climate changes, I fail to see the linkage between this line and the topic. Harmful, in what way? Does it cause climatic changes?
Emm, I think your measures to control climatic changes could've been more general instead of only focusing all the responsibilities on the government. So perhaps:
World organisations such as the United Nations can come to hold campaigns.. Countries to sign agreements to limit greenhouse gas admissions.. Other than the bans and agreements, that are only 'hard' measures to stop the alteration of climates by man, man needs to know the negative impacts of climatic changes so as to truly sense the need to control the climatic changes and thus to come up with even more productive ways of countering to that change. Education is the key to that..
I thought your essay was good already,
I just wanted to share my ideas too :D
I hope it did some help :]
Do retaliate if what I wrote seem to have some inaccuracies.
Its all about learning!
Thankyou!
