Sustainability is not an option; it's a responsibility we owe to future generations.

The limits of the possible can only be defined by going beyond them into the impossible.

可持续林业不仅仅是砍伐树木，更是确保未来有森林可供珍惜。

You can't use up creativity. The more you use, the more you have.

Sorrow is hushed into peace in my heart like the evening among the silent trees。
