I would change energy sources. Well, more of adding a new source or even modifying an existing one. I would change this energy source to be an infinite energy source that humans can use effectively. Now sure this might not save everyone on this planet, but what we could do with this new found energy would be very interesting. For example, flying cars would now be a piece of cake to make. Your phone would never need another charge in its life. What would be the most intriguing to me would definitely be the new inventions that humans would come up with. Things that we’ve never even imagined before would come to be.
