Having studied biology really helped me a lot because I quickly understand how biological systems work, and how they fail, and the tragedy of when they fail, because we are dealing with life systems, and when we hear that a species has become extinct, or is threatened, you realize that this could mean that this species will disappear from the face of the earth forever! So that understanding really gives you energy to do something to save it.
Wangari MaathaiQuite often when you help poor people, they don't think about the environment. They think about survival.
Wangari MaathaiAnybody can dig a hole and plant a tree. But make sure it survives. You have to nurture it, you have to water it, you have to keep at it until it becomes rooted so it can take care or itself. There are so many enemies of trees.
