Future

I'm not one to say what's going to happen to the planet in the future, but I can predict. What I definitely know is that there will be way more advanced technology. Technology will most likely be used for anything and everything. I even recently heard of some sort of 3D printer type of machine that basically "prints" out and forms objects. I have NO idea of how that works but I wouldn't be surprised if in the near future, it were to start being sold. I think cars will no longer run on gas. The gas will be replaced by a much more natural liquid, or they will all be electrical. What I'm not sure about is if the world will be more peaceful and clean, or if it will be chaotic, dry, and ruined. Or maybe there will be no advanced future at all and a horrible disaster happens and humans die out.
