Everyone hopes that tomorrow will be better than yesterday. We all believe that our problems will be solved. But it is rightly said that the future begins today. If we want it to be happy, we need to do something for it now In my opinion, in a global sense, we are all on the threshold of a good future, because our current capabilities are great. We are free and we can build our own lives. Science deepens knowledge about the world, technologies are improved, communication means are developed. All this can contribute to the fact that humanity will solve all existing problems and build a happy future for all.My world of the future is not exactly like fantastic pictures from movies. I'd like to see in the future, we decided environmental problems, serious illnesses, poverty.
