Flying nonstop
Sure, it can be more expensive, but now that I know how much jet fuel is consumed during takeoff and landing, I hate layovers even more. Not only am I melting away hours of my life in those airport lounges, I'm melting the glaciers!

Plugging the leaks
When I heard about the tax credits offered for energy-efficient appliances, I did a home energy audit (energysavers.gov) at my place in D.C., which was built in 1883. I discovered my laundry machines and kitchen appliances could use an upgrade. And don't even get me started on my AC system, which was blowing more hot air than my fellow pundits.

Forgetting fur
Yes, it feels ever so luxurious, but come on: These animals were butchered for their skin. With warm temperatures on the horizon, let's take it off for good.

Flexing my green thumb
I've been gardening for 40 years, since my grandmother Frances in Louisiana taught me the pleasure of cooking with herbs picked right outside the kitchen window. Last year I grew peppers, tomatoes, eggplant, and okra. Growing your own food is spiritually nourishing—and where else in life can you see results in weeks?

Slicing two minutes off my shower
To tell you the truth, sometimes I even skip my shower. That's called eco-friendly laziness.
