Our next smog-reducing policy: deforestation

As Reagan pointed out in 1980, trees really do cause smog. Maybe.

Before we jump on an environmental policy bandwagon, we have to examine facts carefully. Global warming from man-made sources seems to be as accepted as the theory of evolution. The fact is our ecology is complex and poorly understood. Expect surprises such as the tree-smog connection and this surprise to crop up and remind us that environmental policy will never be straightforward.
