response to review from Ms.Fong (By ZhuoMing)

As there are not so many objective proves for my inatial point of view in Topic 1. I changed to Topic 3, which is considered much easiler to choose a side: Should decision-mskers focus primarily on sulfur particles as the way to combat climate change or should they not? Of course, I chose they should not rely on this respectively new thehnology. And I found that there are a lot of arguments I can present in this topic including those in the roundtable we discussed and some other material I found from the Internet.

Some points are: we should not rely on this as there are a lot of uncertainties and it will weaken our determination to reduce the gases emission. Another reason we should not rely on it because the time is limited and we should concentrate on facing the problem from the obverse side. once this method fails, it would be too late for us to restart the reduction of emission or it would be too dangerous to try other methods again.

I think these reasons are more valid and objective. And as this is only the first draft of my essay on Topic 1. I will still modify it after the conference.
