This will be a game changer, he argues, explaining that he copied the idea of a 6 per cent pledge from America, where similar handouts have helped start a dramatic expansion of shale gas extraction since 2010.

他表示：这将改变局面，并解释称，6%分成的想法是从美国照搬过来的。自2010年以来，美国类似的分成计划帮助启动了页岩气的大规模开采。

It is profitable to drill to depths more than 1,000 feet for oil and gas extraction, but only recently in California has it become profitable to pump water from this depth.

从一千英尺以下的地下开采石油和天然气是有利可图的，但直到最近，在加利福尼亚州从这个深度以下抽取地下水才变得有利可图。
