Then I am a criminal since I tend to drink diet sodas and they often
come in an aluminum can. I suppose a large 2 liter might be the best
way to go, but I am not sure. I think this puts a spotlight on the
issue. Often times we do not know what is the best enviromental
choice. The reason is that measuring all the actual costs is
difficult and trying to measure the external costs is most likely
impossible (I mean that is what part of externality means after all
that the part of the costs are paid by others in "unseen" ways such as
increases in pollution).
