Have you tried to do a search online for ideas? I simply typed "Does the world need love" as a search phrase and actually saw similar discussions on other forums.
I think if you stop looking at the question as a trick question and actually think about it. What do you really think? Do you think there's enough love in the world? If so, why? If not, why? Does everyone seem happy to you? Fortunate? Anyone you can think of that is sad, lonely, void of love?
I think you will enjoy the topic more and give a very good presentation if you actually look deep inside you to find your strongest feelings about the topic, than if someone feeds you their ideas which you may not truly believe in.
Good luck.
