Ever looked under the hood of a car from the 50's?

In the LA area, air concentrations of volatile organic compounds declined
by a factor of 50 between 1962 and 2012. Nitrous oxides and ozone declined
by 70% to 80% over the same period of time.

As for "dump our trash", dairy farms now get fined for spilling milk.

That said, wave your arms all you want, talk about spilled milk all you
want, the fact will remain that vehicle emissions are a major
contributor to air pollution.

As of 2011, there are over one billion cars in operation daily
on planet earth. The implications are obvious.
