re: Been there, done that
If you are burning Gasoline, then you are part of the problem. We all are. That is, if there is really a problem. We don't know for sure. Like I said, there are some scientists who think we may be headed for another ice age.
We don't have all the facts yet.
Should we try to clean up the environment? Sure- as much as possible and I believe every years we are getting better at it. Considering our growing population, we are emitting less CO2 than we did in the past. Can we improve- yes.
