Environmental problem is one of global problems of modernity. It is closely linked with issues of resourcedefinition. ecological safety and ecological crisis. One of the solutions to environmental problems is the path of "sustainable development", proposed as the main alternative to the development of human civilization.Scientists claim that from about the 1960s-70s environmental changes under human influence became global, i.e. affecting all countries of the world, therefore they were called global. Among them the most relevant:climate change of the Earth;air pollution;the destruction of the ozone layer;depletion of fresh water and the pollution of the waters of the World ocean;land pollution, destruction of soil cover;the impoverishment of biological diversity, etc. Экологическая проблема — одна из глобальных проблем современности. Она тесно связана с вопросами ресурсодефицитности. экологической безопасности и экологического кризиса. Одним из путей разрешения экологической проблемы является путь «устойчивого развития», предложенный в качестве основной альтернативы развития человеческой цивилизации.Ученые утверждают, что примерно с 1960-70-х гг. изменения окружающей среды под воздействием человека стали всемирными, т.е. затрагивающими все без исключения страны мира, поэтому их стали называть глобальными. Среди них наиболее актуальны:изменение климата Земли;загрязнение воздушного бассейна;разрушение озонового слоя;
- Hi, Mark! I have not seen you for ages. - Hi. I have been working quite hard as usual. How about you? - Great. I have been looking around for a new flat, but I have not found one yet. - What’s wrong with your old one? - It’s OK. But I have just got a new job and it’s on the other side of town. By the way, have you finished that book I gave you last month? - I have not have time, I was very busy. I have started it but I’ve only got as far as the first chapter. - What you have been doing since I last saw you? - I have been preparing for exams, of course. I have took maths I’ve still got physics and chemistry to go. - How did the maths exam go? - I think I have passed it. We’ll see.
