On that last part, yes it is naive to think that much of any of these
recycling efforts makes any real difference. Some of the stuff we have
been recycling for the longest time such as glass is a net negative
environmentally to recycle, but it makes folks who don't look at the
details feel better.

I think that the bottom line for recycling glass is positive, since
doing so conserves landfill space. Can you imagine the hassle from the
NIMBYs each time we need to start a new landfill?
