*Heaven on Earth: People will live happier than ever as science and technology advance significantly. All the sickness and diseases that are incurable now will be curable in a few decades. Famine will be thing of the past as food production will be increased significantly due to improvement of technology. ect....
*Hell on Earth: Pollution will be skyrocket as every country is building their economy at a very fast pace. Famine is everywhere as the world population is skyrocket but food production is decreasing due to pollution and water shortage. ect... the world is in the chaotic situation.
*Normal: Nothing change much. Science and technology are getting better but there are still problem. Many disease and sickness still not curable. The population is getting higher but at a much lower pace due to birth control. Natural disasters such as earthquake, huricane, flood and ect. still occur just like we they do today. Nothing change much.
*Others??
What do you think?? I think things will be normal in the late 21st century. Nothing change much.
