1. The Great Smog lasted from December 5 to December 9, 1952, and caused visibility to drop to as low as 10 meters in some areas.
2. An estimated 4,000 deaths were directly attributed to the Great Smog, with thousands more suffering from respiratory illnesses.
3. The event prompted significant public health reforms and led to the passing of the Clean Air Act of 1956 in the UK, which aimed to reduce air pollution.
4. Prior to the Great Smog, London was already experiencing poor air quality due to its heavy reliance on coal for heating and industry.
5. The Great Smog is often cited as a pivotal moment in environmental history, marking a shift in public perception towards pollution and its impacts on urban life.

Review Questions

• How did the Great Smog influence public perception regarding air quality and pollution control measures?
  • The Great Smog profoundly changed how people viewed air quality issues, leading to increased public awareness of the dangers of pollution. The extreme health crises that emerged from this event galvanized citizens and policymakers alike, prompting demands for cleaner air and better regulations. It served as a wake-up call about the consequences of unchecked industrial emissions and poor urban planning.
• Discuss the long-term impacts of the Great Smog on environmental policies in urban areas around the world.
  • The long-term impacts of the Great Smog were substantial, as it led to significant legislative changes not just in the UK but globally. The event spurred governments to implement stricter air quality regulations and monitor industrial emissions more closely. Cities around the world began recognizing the need for sustainable urban planning practices that prioritize public health and environmental integrity over industrial growth.
• Evaluate the role of industrial practices before and after the Great Smog in shaping modern urban sustainability efforts.
  • Before the Great Smog, industrial practices often prioritized productivity over environmental health, resulting in severe pollution levels. However, after this event, there was a clear shift toward integrating sustainability into urban development plans. This evaluation reflects how industries began adopting cleaner technologies and more responsible practices as a response to public pressure for healthier living conditions. Ultimately, this evolution has been critical in shaping policies that aim for sustainable urban environments today.
