To reconnect with nature is key if we want to save the planet.

In Tanzania, the chimps are isolated in a very tiny patch of forest. I flew over it 13 years ago and realized that, basically, all the trees had gone, that people all around the park are struggling to survive. It became very clear that there was no way to protect the chimps while the people were in this dire circumstance.

We have turned away from the natural world. Instead, it's all about money and power.

If we allow the destruction of the environment, we can see the terrorists have utterly won, and are destroying the future of our children and grandchildren. We must not let that happen.

We seem to have lost the wisdom of the indigenous people, which dictated that in any major decision, the first consideration was 'How will this decision we're making today affect our people in the future? These days, decisions are made based on the bottom line.

As human beings, we can encompass a vague feeling of what the universe is, and all in this funny little brain here - so there has to be something more than just brain, it has to be something to do with spirit as well.

Without the support of local people, you might as well give up because you can make all the noise you like, you can demarcate a national park, but if the people outside want to go creeping into a forest you really can't stop them. They've got to get a benefit.
