As usual you can't resist talking down, can you?  Why should anyone detail to you their ways of fighting pollution?  Very well, let me be more specific.  Although I indeed produce some pollution, I drive only when necessary, either walking or taking public tranpo for other trips.  I changed all my light bulbs for high efficiency types.  Whenever possible I wash and dry clothing by non-mechanical means, and don't buy non-seasonable fruit or veggies.  I compost, and raise a garden.  I don't preach to anyone else to do so, but many have their own ways of contributing.  I don't ask whether you do so.   I don't believe I am the one being obtuse.  We have cleaner technology today because of efforts by some to improve the air, that's progress.  Why are you carping?
