The world is a very complicated place. I see things on the news, read stuff here on Ideapod. Here is the question for this post.
The world is full of problems. What problems that we have today can be solved now by the resources currently available? This means no portable fusion power supplies, no visits from our alien neighbors, nothing not already here.
I am not asking for a list of solutions, just a list of the problems an individual believes we can solve. Issues that are a burden on most of all, humanity.
