Planting trees is definitely one of the most enjoyable ways to reduce our global carbon footprint. Apart from that, a new study has found that replenishing the world’s tree coverage on a grand scale would suck enough carbon dioxide from the atmosphere to cancel out a decade of human emissions. Scientists have established that there is room for an additional 1.2 trillion trees to grow in parks, woods, and abandoned land across the planet, which could potentially be enough to remove ten years’ worth of emissions. Planting 1.2 trillion trees on all the sites identified by the study is quite unrealistic, but it does show how tree planting is quickly being recognized as a critical activity for preserving life on Earth.
