VI. Give English translation for:

Использование природного газа для удовлетворения различных потребностей человека началось задолго до рождения современной газовой промышленности. Оно имеет такую же богатую и даже более длительную историю, чем использование нефти, битума, асфальта.

Из истории развития человечества известно, что природный горючий газ был известен с древнейших времен, но его использование не имело широкого распространения. В местах выхода его на поверхность земли он иногда загорался, и такой факел существовал долгое время. Эти факелы называли вечным огнем. Первые успешные попытки применения газообразного топлива были предприняты в Древнем Китае не менее чем за 1000 лет до нашей эры. Природный газ добывавли при помощи глубоких скважин и перекачивали по бамбуковым трубопроводам. Он использовался в качестве топлива для выпаривания соли из естественных соляных растворов, а так же для освещения и отопления.

Долгое время газообразное топливо не было известно в Европе и США. Впервые использовать газ в коммерческих целях начали в Британии. Тогда искусственный (каменноугольный) газ стали применять для освещения улиц, жилых домов. Использование природного газа в промышленных масштабах началось гораздо позже – в 70-х годах позапрошлого столетия. Становление же мировой промышленности природного газа началось лишь после окончания второй мировой войны.

Природный газ ныне широко используется в качестве топлива и сырья для химической промышленности. Как источник энергии природный газ является одним из главных на Земле, уступая лишь нефти. Это связанно с преимуществами природного газа над другими видами топлива. Теплота сгорания очень высока, он не оставляет золы и является самым экологически чистым топливом.
