### Environment
Itanagar is nestled in the foothills of the Himalayas, enveloped by lush greenery and a rich array of flora and fauna.
* **Air Quality:** The air quality in Itanagar is generally excellent (AQI is usually 'Good' or 'Satisfactory'), free from the severe industrial pollution seen in larger Indian cities. * **Climate:** The city experiences a humid subtropical climate. Summers are warm and humid, while winters are mild to chilly. The region receives heavy rainfall during the monsoon season. * **Protected Areas:** The Itanagar Wildlife Sanctuary encompasses a significant portion of the capital region. It is home to diverse species, including macaques, capped langurs, and a variety of birdlife (including hornbills, though sightings near the city are rare now). * **Water Quality:** Natural streams provide the primary water source. While the source water is clean, seasonal monsoon rains can cause siltation, making water purification necessary before drinking. * **Sustainability & Recycling:** Environmental awareness is growing. Organizations and local authorities regularly conduct plantation drives and cleanliness campaigns (like Swachh Bharat Abhiyan). Single-use plastics are officially banned, though enforcement is an ongoing process.
