… Particularly, I am interested in the following questions:
1) approx. carbon storage per Hectar?2) approx. emission of carbon dioxide resulting from logging?3) approx. price($) to a megagram of carbon in, added to or removed from the atmosphere?4) approaches to quantify ($) biodiversity per hectar
