World Problem

A big world problem is/will be the nuclear threat of alot of countries. If another great war, or even a third world war breaks out, millions of people will die, because too many countries have atomic bombs. This would be the bloodiest wars ever. When an atomic bomb hits a city, the nuclear radiation spreads and life will be impossible there for hundreds of years.
To solve this problem, the governments should stop building atomic bombs or limit the amount of bombs they have. Wars should be kept away as good as possible and countries should do everything to not to get involved. They also shouldn't be used if wars occur.
