Forests and Climate ChangeThere is great concern that increasing levels of carbon dioxide and other greenhouse gases in the atmosphere are causing changes in the global climate. Forests are considered natural 'carbon sinks', because trees absorb carbon dioxide from the atmosphere as they grow, releasing oxygen and storing the carbon in their leaves and wood. Infact forests are a bit like a giant global air-purifier. They take carbon dioxide and turn it into wood and release clean oxygen for us humans and other animals to breathe. Once a tree has been harvested, it ceases to absorb any more carbon dioxide. If the tree is burned or left to rot on the forest floor, this carbon dioxide will be released back into the atmosphere over time. However, newly regenerated or replanted trees will continue to absorb the carbon dioxide from the atmosphere again. Also, once the tree is made into wood products, like timber or paper, these products continue to store the absorbed carbon. This is another important reason for ensuring that timber and paper products are recycled whenever possible, instead of being placed into landfill More information on Climate Change
