Hey, CG... mg has got more integrity in her doubts than you have in your assurances. Calling a well meaning person an ass is the surest way to become one...

Carbon Dioxide is not the 'big problem' we face in today's environment.

Concrete is beginning to be efectively recycled. Grinding it down is becoming quite cost effective.

Wood rots. An outside deck becomes dangerous in twenty to thirty years here in the NW...

Concrete is only as inflexible and ugly as the forms that made it... which are usually made of wood. Experimentation with new form materials will give amazing results...

Improperly reinforced concrete structures... especially underengineered ones... are indeed more dangerous than your average wood frame sheetrock holder...

But done right, concrete is incredibly strong, durable, inexpensive, and environmentally friendly.

Wood chip technology is ultimately extremely toxic, and wood finishing products are world renowned for their relatively short lifespan and toxicity.

The 'new growth' wood that is being used for exterior trim on the majority of structures being built today is difficult to match at the seams, takes paint in an eratic fashion, and warps incessantly. It just looks shabby.

There is hardly any good wood left in the world, and it should be considered a treasure... lets leave some of it so that our children's children can have nice wood for their musical instruments, floors, and 'bright work.'
