One main world issue is world hunger. Its terrible to think that many people in third world countries can't feed themselves and their families. I think the best way to solve this issue would be to teach them how to farm. If we taught them how to grow food and raise live stock they would be able feed themselves. If some of the first world countries could team up and give them some seeds and some livestock such as cattle, chickens and pigs. After a decade or so most families could have a large enough farm operation to feed themselves at least.
