###Replace#### the old trees with young, rapidly growing trees that
will remove large quantities of CO2 from the atmosphere to manufacture
carbohydrates like cellulose.

Larry, are you not saying "replace" old growth{which means chop down
and and manufacture?}...and replant young growth{which ignores the
role old growth play in bio-diversity}.

Carl Sagan estimated in 1997 that the amount of new growth required
was the size of the USA.

I'm just trying to be certain i've understood you.
