In 2020 life on the Earth can be completely different. I think it will be more modern and comfortable. Technology will develop. Public transport will be more convenient. There will be more skyscrapers. But it is likely that an ecocatastrophe will happen. If people continue throw waste into rivers, cut down the forests, pollute the air, they won't avoid problems. I hope that this won't happen. Many monuments and memorials can be ruined in future. I hope that people save them, too. I don't think a war will start. If it be so, it will be terrible, because many countries have mighty weapon. I hope that people will plant a lot of trees and flowers and take care about our planet. And I think in 2020 it will be more green and more beautiful and amazing!
