Mabye we can force everyone into a huge building that has everything (shops, hospitals, houses, restaurants, schools, etc...) for 10 years while we make earth more of a liveable planet by building roads, removing/reusing garbage, making schools and hospitals more available, and making sure poor places have what they need. We can also build huge, transparent tubes that are wide enough for only 5 people (to try and prevent crowds). These tubes allow you to see buildings, grass, parks, and other people through them. They are always clean and whoever litters has to pay a fine. Then we can asssign everyone to their new homes and jobs, let them out country by country. That way, no one would be too poor, or sick. We can also get rid of diseases by giving food/shelter only to those who took vaccines. I personally wish this would happen because it would help people in need and prevent polution (not entirely just enough to not kill us).
