First of all, consider petroleum. That is all you really need to know.

However, the problems are manifold. Simply manufacturing cars and dumping them in landfills would be enough of a problem to overtake smoking in impact.

Driving the damned things is outrageously stupid for mankind. Smoking doesn't even register on the scale.

Well, it registers on the nanny scale.
