For me planting a tree is a very doable thing. It's not complicated, it doesn't require technology, it doesn't require much knowledge, but it can be a very important entry point into communities understanding how they destroy their own resources, but how they can also restore those resources, and not wait for their government or international agencies to come and help them.

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.

Women are responsible for their children, they cannot sit back, waste time and see them starve.

Quite often when you help poor people, they don't think about the environment. They think about survival.

People are dynamic. They change, and soon as there are enough of you, things change [for a whole society].

The living conditions of the poor must be improved if we really want to save our environment

We do the right thing not to please people but because it's the only logically reasonable thing to do, as long as we are being honest with ourselves - even if we are the only ones.
