I was reading the up/down discussion ( [www.straightdope.com/mailbag/mgeoid.html](http://www.straightdope.com/mailbag/mgeoid.html) )  
and remembered a cute little commentary on the effects of deforestation. If I remember correctly it was intended as a spoof on certain material published by some environmental extremists (not in any way implying that I believe we have no reason to be alarmed).

This might explain why I’ve been feeling light-headed recently. Or maybe it’s just the cold medicine.

So you’re saying we can lose weight by chopping down trees? Easier than diet and exercise.
