The Museum compound is universally regarded as the "green lung" of Thiruvananthapuram.
* **Green Cover:** The 55-acre botanical garden and zoo compound features centuries-old trees, rare tropical flora, and vast landscaped lawns that significantly reduce local urban heat. * **Air Quality:** Generally Good to Moderate (AQI typically between 30 and 70), benefiting greatly from the dense canopy and proximity to the coast. * **Sustainability Rules:** The entire museum and zoo complex is a strictly enforced **plastic-free zone**. Visitors are not allowed to bring single-use plastics inside. * **Water Bodies:** The compound features ornamental lakes and water conservation systems designed to sustain the zoo's animal enclosures and botanical gardens.
