Jamie Simpson's thorough review addresses nutrient depletion and biodiversi=
ty losses as well as carbon balances.
While in one sense David W's comments are correct in that the carbon in tre=
es had been taken out of the atmosphere before harvest and thus any return =
by burning or decomposition has already been paid for, in 2015 we have to b=
e concerned with increases in the near future, so the issue of how long it =
takes to reabsorb CO2 released by biomass burning is relevant. As well, if =
productivity declines with successive harvests, there is a net increase in =
contributions to the atmosphere.
There is abundant reason to be concerned about declining productivity of ou=
r forests associated with loss of calcium, as we have some of the most poor=
ly buffered systems in North America and Europe, and possibly for N.A., the=
most intensive forest harvesting historically. The loss of our salmon in o=
ur rivers should have been the canary in the coal mine for our forests.=C2=

=C2=A0Barrie Goldsmith estimated in 1980 that our forests had been cut over=
an average of 4X since the Europeans arrived, and we can probably now add =
at least 1 more to that figure. To the extent that productivity declines wi=
th each harvest, CO2 shows a net increase accordingly over the full harvest=
cycle.

My efforts to get some response from NDP and Liberal Governments =C2=A0& DN=

mental Law and others pursue them and to see them being discussed in this f=
