Hmm.. Good question. I think we will solve alot of the energy problems over the coming years so I wont pick that..
Maybe something around developing something that would allow us to reclaim barren land. In Africa, for example, there is lots of land that is pretty much useless. People need to travel huge distances for food, fuel and water If we could find a way to plant trees and plants, then this would provide food, shelter, power etc. many of the ingredients needed to be sustainable. These trees would also help combat the effects of pollution etc. Yea I think thats what I would do 🙂
