Global Warming 101

Laurie David, the wife of Seinfeld co-creator and Curb Your Enthusiasm star Larry David, says they've made small environmental changes in their home that anyone can follow. "One thing about helping the environment is it's not about being perfect," Laurie says. "I'm not perfect—I don't bike to work and I don't read by candlelight—but it's about doing something. Everybody doing a little bit in their day-to-day lives to make a difference. And it does make a difference."

Laurie says there are four changes anyone can do to help the environment:

• Use compact fluorescent light bulbs. "Listen to the statistic from the EPA report," Laurie says. "If every American household changed five regular light bulbs to compact fluorescent bulbs, it would be like taking 8 million cars off the road."
• If you bring clothes to the dry cleaners, bring along a garment bag instead of having them wrap your cleaned clothes in plastic.
• Unplug appliances when you're not using them, even though you may think they're off. "For example, when you take your phone off, if the charger's still in the wall, it's sucking energy and that's costing us money and costing us emissions," Laurie says. "Everything needs to be pulled out of the wall: your coffee maker, your toaster, your hairdryer."
• Buy toilet paper made from post-consumer waste paper—that's recycled paper!
