How we are using up our home how we are living and polluting the planet is frightening. It was evident when I was a child. It's more evident now.

Let me tell you never before in the history of this planet has anybody made the progress that African-Americans have made in a 30-year period in spite of many black folks and white folks lying to one another.

Through all of history mankind has ingested psychedelic substances. Those substances exist to put you in touch with spirits beyond yourself with the creator with the creative impulse of the planet.

For the sake of our health our children and grandchildren and even our economic well-being we must make protecting the planet our top priority.

I always remembered that when I saw people get married they got on a rocketship and went to Planet Happiness Population: Them.

In securing the future of the planet we secure happiness for ourselves. One of the aims of the Greens is to turn around the tide of pessimism amongst the young people of the world.

For this generation ours life is nuclear survival liberty is human rights the pursuit of happiness is a planet whose resources are devoted to the physical and spiritual nourishment of its inhabitants.

I feel good in my own skin because I've accepted the fact that I'm me. That's what's so great about being alive and being on this planet: Everybody's different.

To hear some men talk of the government you would suppose that Congress was the law of gravitation and kept the planets in their places.

Ten percent of the big fish still remain. There are still some blue whales. There are still some krill in Antarctica. There are a few oysters in Chesapeake Bay. Half the coral reefs are still in pretty good shape a jeweled belt around the middle of the planet. There's still time but not a lot to turn things around.

I like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe - because like Spinoza's God it won't love us in return.

It is not known precisely where angels dwell whether in the air the void or the planets. It has not been God's pleasure that we should be informed of their abode.

Only one thing is impossible for God: To find any sense in any copyright law on the planet.

Whether things turn out for the better depends on what we do. We ought not spend our time masterminding the future but recognize our marching orders: to do the best we can for history and the planet.

We need to think of the future and the planet we are going to leave to our children and their children.

I really hope that we'll have a sustainable future on this planet I really do. So I probably geek out mostly about learning more about how potentially we can hopefully make that happen hopefully we're not too far lost.

We owe at least this much to future generations from whom we have borrowed a fragile planet called Earth.

I believe it is essential for our planetary future to develop tools that can change the consciousness which has created the crisis that we are in.

The future is going to be boring. The suburbanisation of the planet will continue and the suburbanisation of the soul will follow soon after.

The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.

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.
