Many of us who grew up playing golf know that our kids aren't doing it. A great way to enhance the game, make it cool again and bring back some of the interest among younger people is to make golf the greenest sport in an environmental sense. Every course's greenkeeper should think of himself or herself as the greenkeeper: responsible for preserving the green, not just the greens.

A golf course should aspire to generate as much energy as it consumes - golf should be leading the way toward energy net zero.

I have no problem with a war for oil-if we accompany it with a real program for energy conservation. But when we tell the world we couldn't care less about climate change, that we feel entitled to drive whatever big cars we feel like, that we feel entitled to consume however much oil we like, the message we send is that a war for oil in the gulf is not a war to protect the world's right to economic survival-but our right to indulge. Now that will be seen as immoral.

If you followed this economic crisis and you do not think that the world is getting flatter, you are not paying attention. We saw the entire global economy at one time acting totally in sync. The real truth is the world is even flatter than I thought. Our mortgage crisis is killing Deutsche Bank. You still don't think the world is flat?

Everyone needs to get together and say: "Our objective is to preserve and enhance the game and the planet on which it's played. To make golf a leader in greening the world."

Remember, the difference between the world frozen over, in an ice ball, and the warming period we're in now is just 6 degrees centigrade. A change of just 1 degree can have a huge effect.

Once people get a taste for whatever you want to call it - economic independence, a better lifestyle, and a better life for their children - they grab on to that and don't want to give it up.
