Re: [GreenYes] plastic lumber
I cannot help laughing (and of course, i do NOT mean this personally) at
David Wollner's comment "If plastic can be made from renewable resources
and in a non-polluting way, then by all means lets make lumber."
Lumber--the real thing--is made of cellulose, a polymer, made by Nature in
as non-polluting and renewable way as can be imagined, namely
photosynthesis.  If humankind is to embrace sustainability, as it MUST,
then much of our effort should be focussed  using renwable resources like
trees and crops, in place of petroleum and coal.  Before WWII, many
products were based on carbohydrates:  glue from soybeans, rayon fiber from
cellulose (probably wood), etc. Linoleum derives its name from linoleic
acid which cames from either corn or soybeans.  The list goes on.  In
making chemicals from petroleum we, with the help of the chemical industry,
have become chemically dependent--addicted to a never-ending flow of oil.
In addition, we have created monstrosities like PCBs, dioxins,
chlorobenzenes, etc. which persist in the environment, and are toxic.
    Are carbohydrates a panacea?  No. Are there complicating issues like
genetically modfied crops? Of course.  But overall, we have to get off our
addiction to oil.
