Could you please help me review this paragraph and make any correction if needed (grammar...misused word, and so on)?


Topic: Some people think the advantages of international tourism outweigh its disadvantages. To what extend do you agree?

My introduction paragraph:
International tourism is increasingly popular nowadays because of the highly developed world transportation system, commercialization and many other factors. But at the same time, controversy has arisen over whether international tourism has more benefits than drawbacks. Some assert that international tourism can usually bring more positive results. Speaking for myself, I agree with this proposition, with certain qualifications.

Many thanks,
Lei

Comments:
I deleted "usually" because it doesn't fit with the context of the paragraph, "often" is a much better fit to what you seem to be saying.
"more" doesn't have any reference in the rest of the paragraph. Presumably you mean "more positive than negative results" but from the paragraph alone that is not clear.
There is something not quite right about the overall paragraph. It seems like it dances all around its point but never really makes its point. Maybe some actual examples of good and bad results of international tourism would help.

But at the same time, controversy has arisen over whether international tourism has more benefits than drawbacks. Some assert that international tourism can often bring more positive results than negative ones, and it could benefit many areas such as economy with less trade-off to make. Speaking for myself, I agree with this proposition, with certain qualifications.

again, thanks for your help, and let me know if the modified version OK?
