Why has it seemed that the only way to protect the environment is with heavy-handed government regulation?

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.

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.

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

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

I believe strongly that we need to get beyond rhetoric, beyond industry and environmentalists fighting with each other, and seriously solve problems.
