What's near and dear to my heart is cooperative conservation.

Growing up in Denver, I'm sure it started with loving the Colorado mountains.

Dense overgrown forests and rangelands have grown like a cancer. They need to be treated.

In Washington, there's always an effort to label people.

We also know that China and India, as their economies ramp up, are using more and more energy.

We do have serious energy needs for the country, we are aware that natural gas is especially in demand because of its air quality benefits: 90 percent of new power plants have been natural gas-powered.

I think the greatest challenge in environmentalism and the most rewarding challenge is trying to figure out how humans can meet their needs while protecting the environment.
