* **Protected Areas:** Home to the Nilgiri Biosphere Reserve, Gulf of Mannar Marine National Park, Mudumalai National Park, and Anamalai Tiger Reserve. * **Air Quality:** Coastal cities like Chennai generally experience moderate air quality due to sea breezes, though it can dip during winter. Inland industrial hubs and high-traffic areas face typical urban pollution challenges, while the hill stations enjoy excellent air quality. * **Sustainability:** Tamil Nadu is a pioneer in renewable energy in India. The Muppandal wind farm is one of the largest onshore wind farms in the world. * **Green Tamil Nadu Mission:** A state initiative aimed at increasing forest and tree cover to 33% of the state's total land area over a decade. * **Water Conservation:** The state mandates rainwater harvesting for all buildings to combat groundwater depletion, a critical issue during dry years.
