The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.

"To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment."

Never stop learning, because the world never stops changing.

历史是由胜利者书写的，但记忆属于人民。
