This time instead of moving oceans and healing planets let's get our bills in order and pay down the debt so we control our own future.

Scientists will eventually stop flailing around with solar power and focus their efforts on harnessing the only truly unlimited source of energy on the planet: stupidity. I predict that in the future scientists will learn how to convert stupidity into clean fuel.

The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air water and continents are interconnected. That is our home.

We are the only beings on the planet who lead such rich internal lives that it's not the events that matter most to us but rather it's how we interpret those events that will determine how we think about ourselves and how we will act in the future.

Our most basic common link is that we all inhabit this planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.

I'm calling my book series the 'with God series.' And this next 'with God' book is Friendship with God which comes out in November. This books challenges us to bring about the end of 'better' on this planet.

When friendship disappears then there is a space left open to that awful loneliness of the outside world which is like the cold space between the planets. It is an air in which men perish utterly.

Wherever on this planet ideals of personal freedom and dignity apply there you will find the cultural inheritance of England.

It is not natural or inevitable that half the world goes hungry that the freedom of markets trumps protection of the planet or that citizens' rights come second to those of corporations.

Australia is the only island continent on the planet which means that changes caused by planet-warming pollution - warmer seas which can drive stronger storms and more acidic oceans which wreak havoc on the food chain - are even more deadly here.
