Five of the SDGs are life on land, life below water, good health and well-being, food security and climate action. They underpin and interact with many other SDGs. Healthy ecosystems play a role in mitigating greenhouse gas emissions, not only protecting areas to prevent the release of carbon through land conversion activities but also restoring otherwise degraded land. The United Nations has declared 2021-2030 as the Decade on Ecosystem Restoration and the Decade of Ocean Science for Sustainable Development. Restoration means actively or passively allowing habitat to return to its natural state , including replanting native vegetation. This can benefit the recovery of biodiversity, help remove carbon dioxide from the atmosphere and improve the delivery of nature's contributions to people, such as climate regulation, water purification, pollination, and pest and disease control. Thus, protecting biodiversity helps to meet two SDGs directly, and three indirectly.
