This issues you must wrestle with the threat of climate change, food scarcity, and population growth, worldwide terror based on religion, the interdependence of the world economy my student generation would barely recognise. But the difference today is they are all essentially global in nature.
气候恶化，粮食短缺，人口增长，以宗教为基础的全球恐怖主义，以及世界经济的相互依存都是我们必须要解决的问题，我往届的学生很少会认同这点。但今天，不同的是，这些都已经成为全球的实质性问题。
