Global Warming and our Changing World

I think it was on Yahoo today that I read that divorce is bad for the environment. I read through the first sentence or two, that's it, because the basic idea was right in there. It said the reason for the negative impact on the environment is that a divorced couple use two residences, and not one. So if they're wealthy enough, that could mean two separate houses. To radios playing the same song. Two televisions with the same news. Two sets of lights, two furnaces, two air conditioners.

It makes sense. But what is the reverse, the solution? Get married, or stay together. Or, carpool your living arrangements.
