Which is better for the environment: Email or Snail Mail?

I would have to say email. Email requires only about 20 minutes of electricity when you type and send or check then you can shut off your computer. But post office mailing requires someone to drive over in a car emitting fumes into the air and then going back to the post office, then deliver it and probably 100 others. All that driving is bad for the environment. Also operating the equipment required to sort out the mail uses quite a bit of electricity. Then you have to consider the mail being delivered across the globe by plane or ship then being driven around. That harms the environment as well.
