Even though the time we live in has some controversy, I feel like the future will be much more peaceful. About a year ago it seemed like there was going to be a WWIII because of North Korea, But now that they have agreed to denuclearize there seems to be no world changing wars in the near future. People will still probably not get along and there will be wars in the Middle East, but they will most likely end in a couple years. It would sadly be impossible if everyone in the world decided to be friends and helped each-other to populate other planets for example because of how different cultures are, But maybe we could all individually focus on inventions to help the human race or the Earth and not weapons to win a war that is not there. Problems will still be on earth such as overpopulation which will be very hard to solve because Humans will run out of food. Running out of space is not a issue because of how much land is on Earth. In the future there may also be bases on Mars. I know it sounds science fiction but we are very close to sending a man to Mars. But no one will ever be able to guess how the future will be.
