Forestry has been mentioned. I know more could possibly be done in this area. Because of our history, we have a psychological aversion to sowing trees on land. We will need to get over this, whether through education or otherwise. Long ago growing trees was seen as the preserve of the wealthy farmer, but that is no longer the case. In particular, we do not have nearly enough hardwoods. The farming community has an aversion to putting good land under trees and I do not know how we will get around this. However, some policy should be put in place.
