SDG 15 focuses on protecting and restoring terrestrial ecosystems. It addresses issues like desertification caused by overgrazing, habitat loss driving animal extinction with 150 species lost every day, and deforestation intensifying climate change. Achieving the goal requires indicators like forest area proportion, degraded land proportion, and endangered wildlife trade. Actions to support the goal include breeding programs, tree planting projects, laws protecting nature, and reducing consumption of endangered species and non-seasonal imported goods. Progress is measured using indicators like forest area and threatened species.
