Old-growth forests hold vast amounts of carbon from centuries of growth, and this carbon would be released into the atmosphere if the trees were cut down. That much has been known for a long time, which is why Environmental Defense Fund so strongly advocates a plan to reduce deforestation in developing countries.
But new research shows that old-growth forests are even more important than previously thought. According to a new study in Nature, old-growth forests aren’t just standing there maintaining the status quo. They still actively take up CO2 from the atmosphere.
