2100 – distant future. powerful technology, books will be gone, will replace their hologramy. machines also will not be, as it will be more convenient transportation, and we will move through the air. trees also would not be possible and many common animals will become extinct because people are very quickly destroying everything in their path for their own purposes. factories will be so many that half the world will suffocate. many wars will be in the future. very often we are spoiling your life in the future. maybe it's time to stop, and just to love nature, not destroy their place under the sun in the year 2100?
