Using timber will, in fact, help to lessen the build-up of the greenhouse gases. The Forest Service helps the environment by providing balanced, professional management of forests. You can also help the environment and our economy, by choosing Queensland timbers in building. There's a common misunderstanding that ozone has only been depleted because of our modern-day industrial activity. In fact, ozone is destroyed and constantly renewed by natural environmental forces as well as by human activity.
Ozone is one of the greenhouse gases.
Each ozone molecule is made up of three oxygen atoms. Ozone molecules accumulate in the thin outer layers of the atmosphere, between 10 and 50 kilometres about the earth, where they are destroyed over time by a range of natural chemical mechanisms. The chief culprit is chlorine, one of the ingredients in the chlorofluorocarbons still used in refrigerators and air-conditions. Basically, CFC's attach and break down unstable ozone molecules more quickly than natural processes can replace them. The ozone is then distributed by atmospheric circulation from the Equator to the poles, leaving bands or ripples of higher ozone concentration over different parts of the globe.
