Although there are significant hurdles, geologists say that the Vaca Muerta is a harbinger of a possible major expansion of global petroleum supplies over the next two decades as the industry uses advanced techniques to extract oil from shale and other tightly packed rocks.

虽然还有重大困难没有克服，不过石油产业已经能使用先进技术从石岩中提取石油了，冰山学家认为，未来二十年巴卡慕艾塔冰川或许能为世界提供丰富的石油资源。

虽然油田开发困难重重，但是地质学家说，现在石油产业已开始利用先进技术从油页岩等岩石中提取石油，瓦卡穆埃尔塔油田的发现预示着，在今后二十年全球石油供应量将有较大增加。

hurdles指的是油田开发困难

Each year it has become harder for family farms to compete with industrial scale agriculture—heavily subsidized by the government—underselling them at every turn. In a system committed to the health of farms and their integration with local communities, the result would have been different.

政府年年拨给农业大笔补助，家庭农场每轮产量都低于产业规模农业，越来越无法正常竞争。如果社会体系关注农场健康，助力农场融入当地社区，结果会大有不同。

现在，农业实行规模化生产，政府给予大力补贴，大型农场的粮食售价自然会处处低于家庭经营的农场，致使这些家庭农场在竞争中日益处于劣势。如果美国在粮食生产体系中切实关注农场的健康发展，统筹兼顾农场与当地发展，塔特尔农场就不会落到这般田地。
