What Life Will Be Like in 2100
People have always been curious about the future. They often make predictions and share their visions of the world in a hundred years from now. Here is what I think about life in 2100.
Scientists believe that by 2100 the population of our planet will have increased by 3–4 billion people. Besides, life expectancy will probably reach 125, especially if we learn to make synthetic hearts, livers and other organs and find cures for all diseases. So the most important problem to solve will be the problem of food supply. In my opinion people will have to turn the oceans into huge farms where there will be plenty of fish and seaweed. Another significant problem will be controlling the weather. I hope people will be able to invent technology to stop hurricanes and tornadoes and to send rain where it is needed. I also think there will be fewer languages spoken in the world and all educated people will speak English and Mandarin. I am sure humanity will find reasonable solutions to global environmental problems. For example, all industrial enterprises could be hidden underground far beyond city boundaries. Thick forests will grow above the plants. Workers will go there by high-speed electric trains daily.
Perhaps my vision of the future is too hopeful, but I believe it is better to look to the future with optimism instead of negative ideas.
