Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

Let's make hay while it lasts.

Perhaps the single most important thing that we can do to undo the harm we have done is to fix firmly in our minds the thought: the earth is alive.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

The oil companies regard nuclear power as their rival, who will reduce their profits, so they put out a lot of disinformation about nuclear power.

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

Time is exactly the amount of wealth God gives to each and every one of us on a daily basis

Those things that hurt, instruct.

I've got two shirts still missing from the Bahamas. I'm sure they are part of a youth camping programme somewhere in Tanzania by now.

On my tombstone they will carve, "IT NEVER GOT FAST ENOUGH FOR ME.

Love of Allah is the power of the heart, the sustenance of the heart, the light of the heart.

When we suffer we have made it into a personal affair. We shut out all the suffering of mankind.

One of the little-celebrated powers of Presidents (and other high government officials) is to listen to their critics with just enough sympathy to ensure their silence.

A long-playing full shot is what always separates the men from the boys. Anybody can make movies with a pair of scissors and a two-inch lens.

Shall I redirect my life's journey because down some side road might be some trifle I'm entitled to?

I contend that it's impossible to read the Sermon on the Mount and not come out against capital punishment.
