нет ты ошибаешся вероятно ты забыл умножить площадь на 2 ведь лыжи две а тзначально находится только площадь 2

Interviewer: Life is change, and the only thing that's certain about the future is that it is uncertain. So what does the future hold for us? A step forward in humanity's striving for perfection? A general nervous breakdown as the environment changes faster than we can adapt to it? We asked Clark Frinton, a theoretical physicist, for his views. Clark, are you optimistic about the future?Frinton: Generally speaking, yes. But we have serious problems to solve, and I don't think we will have solved them all by the middle of the century. Our prime goal must be to ensure our survival, and I think, there are two main problems we need to solve in this respect: ensuring enough energy and food while preserving our environment. To take energy first, at the moment we are largely using fossil fuels that pollute our environment and contribute to the global warming that could lead to rising sea levels and to the depletion of the ozone layer that lets in solar radiation that could endanger mankind's existence. The present alternative is nuclear fuel, which, while not directly polluting the environment, contains untold dangers from radiation — remember the Chernobyl and Fukushima nuclear power plants catastrophes. Therefore, we need an alternative source of energy. I think the future lies in fusion1 power.Interviewer: But as I understand it, it takes more energy to initiate a fusion reaction than the process actually produces.Frinton: Yes, that's true at the moment, but we're making progress. If we can solve that problem, then we'll have unlimited cheap power, and we should reduce the greenhouse gases and global warming. We may even be able to heat our houses and power our cars in this environmentally-friendly way.Interviewer: Clark, you mentioned energy and food. What about food?Frinton: Well, considering the expected increase in population, I think, our only answer is the greater use of genetically modified food. To feed the extra billions, we have to develop new methods of growing crops and increasing yields. Farmers will be using synthetic soils, and new forms of micro-organisms, plants and animals will become commonplace. Soon we'll be seeing fields of identical sheep, genetically engineered for their meat or their wool, if there is space available.Interviewer: But if we interfere with the genetic structure of the food we eat, might we not also interfere with out own genetic structure?Frinton: That's theoretically true, and GM food must be thoroughly2 tested. But my belief is that we will be able to produce safe GM food, and that most people on this planet will be eating it as part of their normal diet.-
