3Kolkata, India
Kolkata, once the capital of British India, is known for its colonial architecture and cultural richness. Yet, it also struggles with sanitation issues. Streets in some districts are crowded with litter, open drains, and inconsistent waste management.
Pollution from vehicles and nearby industries affects air quality, making certain areas challenging for sensitive visitors. Kolkata’s unique culture and historical sites make it worth a visit, but travelers should be prepared for messy streets in busy neighborhoods.
