I'm from Minnesota. I'm optimistic. I mean, that's just who I am.

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.

When you study history and look at every civilization that has grown up and died off, they all leave one remnant: a major sports colosseum at the heart of their capital. Our fate can be different; but only if we start doing things differently.

Water is our next great environmental challenge. It is the new oil. How are we going to preserve this sport unless we are designing and maintaining golf courses that are energy net zero, carbon net zero and water net zero? Or ideally, energy positive, carbon positive and water positive, where they are taking out more than they are using.

Some would ask which country am I from? We are supposed to tell the truth, [so] we tell them India. Some thought it was Indiana, not India! Some did not know where India is. I said it is the country next to Pakistan.

Why is it Muslims from Pakistan or from Egypt come to America and thrive, and they are frustrated back home? It's about clean government. It's about a rule of law. It's about intellectual property protection. They've got all the talent and energy of anybody else. As new immigrants they may have more of it, so you put them in our system and they become doctors, lawyers, and businessmen and entrepreneurs.

There is definitely global warming, and man is definitely contributing to it. Go out to, say, Montana and talk to some pretty conservative people, hunters and fishermen. They know that in the trout stream they fished when they were growing up, the trout are stressed because the water temperature is going up. They know the hunting season has been delayed because the snows are coming later, and therefore the elk aren't coming down from the mountains.
