On the other hand, well thought out action on the environment can make us all better off, both in standard of living and in quality of life. For instance, I think that electric cars, either battery or fuel cell, would materially improve everyone's quality of life by eliminating the noise and fumes even the cleanest, best muffled internal combustion engines generate. If my electric bill could be reduced by reasonably priced solar cells on the roof, my standard of living would improve by a little bit. I'm sure you can think of many other examples.
