Sustainability isn't an option; it's our responsibility to future generations.
可持续性不是一种选择；它是我们对后代的责任。
过去从未死去，它甚至还未过去。
The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart.
我曾经以为世界是按部落划分的。然后我以为它是按贫富划分的。然后我以为它是按愚蠢和聪明划分的。但现在我知道它是按活着的人和死去的人划分的。
