In my opinion, after 300 years, there will be a lot of changes on our planet. I think that after many years the Earth will reach its development peak. Cars will be replaced by flying devices. Robotics will develop. Much work will be done by robots instead of people. People’s role will be secondary. Robots will rule villages, cities and even countries, because robots don’t need to sleep, don’t need to visit doctors, don’t need to have a rest. They just need a power to run it. Poverty will disappear, and there will not be homeless people. I think that after 300 years, there will be many tourist resorts created in space. People will contact aliens and will be friends. I think scientists will create a time machine, which they will use only for research purposes. Scientists will create something that will help to change the weather.
This is what I imagine about our Earth after 300 hundred years…
