Goal Fifteen: Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, halt and reverse land degradation, and halt biodiversity loss

The San Diego region enjoys a high quality of life, although challenges still remain. SANDAG's 2021 Regional Plan seeks to improve the way we all move throughout the region while seeking to ensure that we can all lead healthy lives.
