Our planet is home to over three trillion trees. The world's forest floors help to control global temperatures, clean the air we breathe and hold water in our atmosphere.
However, decades of urbanization and deforestation have threatened the future of many of the world's ancient forests. So in 2019, the United Nations Environment Program launched the decade on ecosystem reforestation, calling attention to the need to restore ecosystems and highlighting the importance of reforestation to job creation, economic security for communities and the role of trees in mitigating the impacts of climate change. This objective includes restoring up to 350 million hectares of land, which would simultaneously remove 26 gigatons of GHG emissions.
