Drive gently.

I am a big proponent of public transportation, but even so, I still have a car. Thankfully, cars don't have to be that damaging to the environment or to ourselves. Try one of these options to cause less harm while you get there:

* Drive a hybrid vehicle. These use gasoline and electricity to generate power and never have to be plugged in. You can learn more at hybridcars.com.

* Use biodiesel to fuel your diesel engine.

* Consider an all-electric vehicle. You'll have to plug it in, but you'll get clean air and a quiet ride.

* And if you have a regular gas car like mine, try some of these 20 tips for fuel-efficient driving.

Happy motoring!

"Ellie: A soul is a very expensive thing to keep: much more so than a motor car. Shotover: Is it? How much does your soul eat? Ellie: Oh, a lot. It eats music and pictures and books and mountains and lakes and beautiful things to wear and nice people to be with." - George Bernard Shaw (1856–1950), Anglo-Irish playwright, critic.
