Hi Greg and all,
While I agree with the sentiments about maintaining old growth
forests and supporting those who agree never to log their plantations
- from an ecological point of view - it's not true to say that only
such situations are effective at sequestering Carbon. In fact, once
an old growth forest reaches a mature equilibrium, it is almost
carbon-neutral itself. While there are certainly ecological and
water issues to be taken into account, as well as the carbon released
in the harvesting process, it is only actively growing forests (or
other forms of plant biomass) which are truly effective as a 'carbon-
sink'. The challenge confronting the 'great minds' of our time is
how to remove as much carbon dioxide and other 'greenhouse gases'
from the atmosphere as possible without unduly upsetting other
ecosystems.
