would End Childhood Obesity be an OK title.. or is that vague?
Ms. Sue
It would be OK. Is your thesis about how to end childhood obesity?

But write the essay before you give it a title.

we have to give an opinion on a global issue
Ms. Sue
Childhood obesity is mainly a U.S. problem. It is not a global issue.

Civilians owning assault rifles is also confined to the U.S. It is not a global issue.

Please research some of the ideas that Bobpursley posted for you.
