Which is why I added those other options. Some people find certain things abhorrent and othere find them totally acceptable regardless of the potential damage that they cause. My point was more about us being willing to challenge ourselves, not only other people's actions but our own as well. My own thing is that I drive everywhere, I know that cars are polluting but it doesn't stop me from doing it and my little 1.6 engine has the fuel economy of a Jag. Just because we feel that something is good or bad does not mean that it most definitely is.
