Today's WPost has an article on how an environmentalist redid her kitchen in green, or should that be "greenly"? She says she turned down granite for her countertops in favor of recycled glass embedded in concrete because "granite is definitely not renewable -- once it's removed from the earth, it's gone forever."
I'm tempted to mock her--she fails to realize that concrete is made with cement, derived from limestone quarried from the earth, heated in a kiln fired most probably by fossil fuel, combined with sand which is also derived from the earth. (It's not clear to me which counter top would require more energy to make.) But seriously, it's an example of the limited vision we all have. We all argue based on a subset of data because you've got to close your mind somewhere. It's also an example of trends. To this old codger, the idea of a green kitchen seems a bit laughable, but it's taken seriously in the paper and may well be a coming thing. It's how social norms develop, just remember (as I do every time I watch an old movie) how norms on smoking have changed over the years.
