What if we're wrong and there is no climate change? Well, by doing everything possible to address it, we will still use less water, stimulate new energy savings and, in time, money-saving technologies, enjoy cleaner air, and preserve more forests and trees and animals.

I'm pretty much an open book. I am a fanatic golfer and golf nut. If I have three free hours any day, my first choice is to run to the golf course if the weather is nice.

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."

By 'flat' I did not mean that the world is getting equal. I said that more people in more places can now compete, connect and collaborate with equal power and equal tools than ever before. That's why an Indian in Bangalore can take care of the office work of American doctors or read the X-rays of German hospitals.

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.

Change your leaders, not your light bulbs.

What about the rest of life? Respect for the sanctity of life, if you believe that it begins at conception, cannot end at birth.
