在所有时代，困扰人类并给他们带来大部分灾难的大问题，不是世界上是否有权力，也不是权力来自何处，而是谁应该拥有它。
The great question which, in all ages, has disturbed mankind, and brought on them the greatest part of their mischiefs, has been, not whether there be power in the world, nor whence it came, but who should have it.
Every ton of ore we extract carries with it a responsibility to the future.
当人们决定以不同的方式做事时，世界就会改变。
幸福就是珍惜小事。
