I would like to have addressed global warming. Renewable energy sources would be used and fusion power plants would be used, and fossil fuels would no longer be needed. At the same time, the most technologically advanced countries should provide energy and food to the poorest. A balance between demand and supply of land products would be achieved, possibly also by checking in numbers and at the same time by educating the population on sustainability. This numerical control over time would always be diminished due to the good sense of the population at that time educated and aware that they cannot spend, spread and consume as they wish.
