可持续发展不是一种选择；它是我们对后代的责任。
Sustainability isn't an option; it's our responsibility to future generations.
This is an interesting planet. It deserves all the attention you can give it.
The right of nature... is the liberty each man hath, to use his own power, as he will himself, for the preservation of his own nature; that is to say, of his own life.
你的时间无法飞逝是因为我。
