Nitrogen: A Global Challenge (Chinese) from edX

这是一场巨大的风暴。有限的食物、水和能源在不断增长的人口间不均匀的分布着，与之相关的气候变暖使得事情更为糟糕。在所有这些全球性挑战中，氮素起着主导作用。在这里，您将了解到氮素是如何与人类文明息息相关的，而未来氮素是将成为人类的救世主还是恶魔。

氮气的故事既平凡又奇特，即充满激情又饱含忧郁。它既是气候的朋友，也是污染的敌人，是享受饕餮盛宴还是忍受食不果腹也与氮素相关。如果你对氮素的看法还是停留在它只是元素周期表上一个无聊的元素，那么是时候了好好了解以下氮素了。

无论您来自何种知识背景，这一创新性的课程都将教给您关于氮素和全球变化的核心概念，使您能够更好地理解它所代表的挑战和机遇。课程关键主题包括粮食安全、气候变化、空气污染、水体污染和人类健康等。

我们将通过爱丁堡大学屡次获奖的教师团队的教学方法来带你学习本课程。这门课程采用了一种引人入胜且十分专业的方法来展示如何应对全球范围内的氮挑战，以及如何更好地全面系统地应对氮素对人类文明所构成的威胁。

这是世界一流的课程，由拥有数十年从事氮素和全球变化研究的教授授课，是英国和印度专家之间合作的成果，这也是 Newton-Bhabha Virtual Centre on Nitrogen Efficiency 的一部分。

本课程的讨论论坛将借助翻译工具以英语进行监测
