Now we are all used to live in a world that seems to be building for yourself. We live in big houses, equipped with high-tech consumer devices, have the ability to travel great distances thanks to cars, trains, planes. We can also monitor what is happening thousands of miles away, via the Internet or TV. But in my opinion, all this is secondary, because in any case we use the knowledge of the laws of nature and its power to create all of these technologies. And in extreme cases, people can live without it, how our ancestors lived and still live in some primitive tribes.

No wonder that on weekends and holidays, people like to be in nature, because dealing with it helps them to relax, to relax, to gather strength for the solution of important problems in our human world.

I really like the fact that in many countries people have paid attention to alternative energy sources and ecological modes of transport. In this case we cannot be indifferent - we must preserve the richness and beauty of nature, only when this condition is possible and our existence
