Terry,
I'm afraid I haven't had time to follow sometangents of the "redesign" thread so this may be off the point:
> Regardless, essentially trees have zero effect on CO2
> sequestration overall.
Trees in cities keep the area cooler, reducing air conditioning use.
> On death they release 100% of what they have stored.
If burned or left to rot. Dare I mention lumber?
