Most of the homes in this country use wood....framing flooring, etc...
Yes, there is a trend to steel and re-cycled materials...
The timber industry in the south-east depends on a reliable and
replenishable resource, timber (wood). Huge forests are
selectively harvested in checkerboard fashion...yes clear cuts....that are
immediately re-sown for another harvest.
And this marvelous resource is usually pine. Grows quickly. Has a
cured strength comparable to oak.
What's not to love. No guilt here.
