the world when im 25 and 50

i think that when im twenty-five that every thing will have something to do with technology and that every thing will be way more expesive there will probably be new drugs and sicknesses introduced to the world and when im fifty there will probably energy efficient cars that will be powered by water or solar powered and there will probably be mostly solar powered homes and there will probably be no more greenland and they will have found a way to have people live on mars.
