[When answering this key question, why doesn't Lisa Jackson mention global warming?]

Change.org: What cause or causes would you most like to promote as a Changemaker and why?

[EPA head Lisa P. Jackson] Broadening the way we think about environmentalism is critical. Environmentalism isn't a boutique issue that affects only a few. And environmentalists aren't professionals and specialists. Protecting our air, water and land is all of our jobs. I want to help people see the many ways that environmental issues affect their daily lives. Children's health is affected by chemicals in the products we buy and use in our home. Water and air pollution prevent businesses from investing and creating jobs in our communities. Environmental triggers send people to the hospital with asthma and other breathing problems. Environmentalism is about where we live, work, play and learn. Expanding that perception helps us address issues from climate change to environmental justice to long-standing concerns about air and water.

Robert Iger on Disney and the Environment - WSJ.com

MR. IGER: Businesses can make a difference. We've got thousands of vehicles at our theme parks around the world. A hundred million visitors on an annual basis. What they consume, how we transport them, how cool the air conditioning is in their hotel room when their lights get turned off—there's a lot you can do. And we're finding more and more that our guests want to know about these things.

But if carbon dioxide really threatens to kill our grandchildren, shouldn't Disney shut down the theme parks immediately?
