Karachi has consistently held the unenviable title of being the world’s most polluted city according to the Air Quality Index (AQI) for three consecutive years. This alarming trend highlights the vulnerability of the city’s residents, who find themselves in a precarious situation.
The AQI registered a reading of 220 for Karachi, surpassing the unhealthy threshold. Any reading above 200 is considered harmful. In simpler terms, the people of Karachi are inhaling air containing particles that can directly trigger respiratory illnesses and worsen pre-existing allergies.
This situation should raise concerns at various policy levels. With the approaching UN flagship Climate Conference, COP28, it is crucial to bring attention to the adverse effects of climate change on our environment and metropolitan areas. Collective solutions should be sought to address these challenges. Effective communication about the multitude of climate-related problems that Pakistan faces due to other countries exceeding safe emission levels should be our first step toward seeking justice.
Moreover, the responsibility also lies with the government. Policies related to urban planning and management should come from district and provincial administrations. If cities continue to grow in a disorderly fashion, we can expect more concrete and fewer CO2-absorbing plants and trees. We are accountable for how we design our cities and the emissions we contribute to the atmosphere through our lifestyle choices.
This crisis demands an urgent response. The annual occurrence of smog in Lahore and the deteriorating air quality in Karachi pose significant threats to citizens’ health and well-being. This is a silent health emergency that won’t resolve itself. It necessitates proactive policies and responses, including global cooperation and environmentally-friendly urban planning.
