Life in the 21st century is developing very fast. If you look on people's lives in your country five years ago you probably will be surprised how it has changed through years. I think life even in 10-20 years will be different from which we have now. And what can we say about the next 50 years?
First of all, I should divide my composition on sections. Because the question of lives changing may be considered from different points of view like changes in technology, climate, politics and so on.
In the next 50 years I think the process of globalization will be moving fast. Unions like the European Union, the African Union and so on may be will be united in federative states. In the world there will be big powerful countries with deep decentralization inside. Unfortunately, a lot of small cultures and languages will die. Probably English, Chinese and Hindi will be the most popular languages, but I think English will keep its managing role in the world. I'm sure that we will see a lot of changes in states structure. Some states will be united in a bigger countries; some states will be divided on smaller parts.
I hope that in future international law will play much more important role than nowadays; nobody won’t begin wars or to occupy alien’s territories. I hope that there will be no more conflicts based on discrimination or hatred and the world will be better. I hope people will live in brotherhood and maybe John Lennon's world will be prophetic.
In the next 50 years technology will obviously change our lives. Even now we can see fantastic robots, inventions and devices that make our lives easier. In the nearest future we'll have robots that will manage in trafficking, medicine, security, and army and so on. I hope with new inventions in medicine and pharmacology people will be able to live longer and healthy.
In general, I think our life will change in a better way but we should work for it. We should solve our environmental problems, problems with peace and security in conflicted regions, fight piracy and banditry. We should use ecologically clear products and minimized harm from the industry. Only this way can bring us to a bright and happy future!
