8Karachi, Pakistan
Karachi, Pakistan’s largest city and economic hub, suffers from numerous environmental challenges. Overflowing garbage, clogged drains, and open sewage are common sights, particularly in the city’s densely populated areas.
The lack of a proper waste management system, combined with unchecked industrial pollution, has led to both air and water contamination. The Lyari and Malir rivers, which flow through Karachi, are heavily polluted with industrial waste. Air pollution, particularly from old vehicles and factories, exacerbates the public health crisis, causing respiratory and cardiovascular problems among the population.
