可持续性不仅仅是一个流行词，更是我们的责任。
Sustainability is not just a buzzword, it's our responsibility.
The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.
凡是能够说的，都能够说清楚；对于不可说的东西我们必须保持沉默。
过去总是紧张的，未来则是完美的。
