8Karachi, Pakistan
Karachi, Pakistan’s largest city, faces significant environmental challenges due to uncontrolled urbanization and industrial activity. The city suffers from severe air pollution caused by vehicle emissions, industrial smoke, and the burning of solid waste. Karachi’s waterways, including the Lyari and Malir rivers, are heavily polluted with industrial and domestic waste, making clean drinking water a scarce commodity. The lack of proper waste disposal systems has led to open dumping sites across the city, contributing to unsanitary living conditions for many residents and posing major public health risks.
