A Sustainable Future

One of my biggest hopes for the future is that man kind can actually find a source of energy that is completely sustainable and can replace our dependency on fossil fuels. This being said, one of my greatest fears for the future is the possibility of running out of fossil fuels. I do not know what the world would do if we ran out of fossil fuels. Mankind as we know it would change forever, we would have to start from ground zero all over again. Its a very well known fact that we will eventually run out of fossil fuels, this is our main limitation. We need to find a replacement fuel source before we run out of the one that we have now. We as people need sources of energy in our world and would be lost without them. None of us want to live in a world with no technology what so ever. Alternate fuel sources are completely necessary in order to keep technology around.
