As a participant in the forest-product industry,have you ever reflected on how your efforts help to improve the global environment?
Almost all scientists agree that we are experiencing global warming due to increased amounts of carbon dioxide in the air.We in the forest-product industry have a significant impact on reducing that carbon dioxide.Consider how trees grow:they grow by absorbing carbon dioxide.When wood is burned as fuel,that carbon dioxide is returned to the atmosphere.
We in the timber industry are carbon steward; we convert trees into building materials and other products that last a very,very long time.Have you ever considered the fact that by producing buildings of furniture we are actually keeping carbon dioxide out of the atmosphere?When we convert a seventy-year old tree into a building product we are extending the carbon-preservation time frame significantly.The resulting buildings could be with us for centuries:in Europe there are a number of well-preserved wooden structures that are more than 800 years old,and in new England there are houses and commercial buildings that are more than 400 years old.In U.S.and Canada we have built over 110 million housing units,amounting to an estimated 800 million tons of trapped carbon.
Moreover,without proper management,forests are consumed by forest fires,which release significant volumes of carbon dioxide back into the air.Only by trapping carbon dioxide in a wood product can we as a society prevent the release of the carbon dioxide.
We in the forest-product industry should be very proud of our mission:planting trees and converting mature timber into products for relatively permanent use by consumers around the world.In your conversation with people outside our industry,try to incorporate these issues in order to show how important our industry is to the global environmental picture.
