Mike L. would say that Trees are Evil because they pump volatile organic compounds into the air, thusly causing global warming and smog. If we cut down all of the trees, there will be no VOC’s to mix with the other pollutants. Go us!
I, however, would say the trees are evil because you can run your vehicle into them. That is why this bi-week’s edition of Talking Traffic concerns clearzone, and why we evil civil engineers cut down all the trees by the roads. This should address the conversation some friends of mine were having at the Landmark Diner during Dragon*Con.
