TREES are one of the most efficient systems of carbon capture and storage on the planet. They breathe in carbon dioxide and breathe out oxygen, locking the carbon into their roots, trunk, branches, twigs and leaves and the soil. They are so good at this that about 20% of the greenhouse gases entering the atmosphere can be attributed to deforestation. In the run-up to the climate talks in Copenhagen in December, bright minds around the world are negotiating a formal scheme for reducing the loss of trees as a way of lowering the world’s carbon emissions.
