Detailed explanation-1: -Located in the crater of an extinct volcano, Mexico City is about 2, 240 metres above sea level. The lower atmospheric oxygen levels at this altitude cause incomplete fuel combustion in engines and higher emissions of carbon monoxide and other compounds. Intense sunlight turns these into higher than normal smog levels.
Detailed explanation-2: -This was partly due to Mexico City’s high altitude (7382 ft above sea level), which causes its oxygen levels to be 25% lower. Carbon-based fuels also do not combust completely. Other factors include the proliferation of vehicles, rapid industrial growth, and the population boom.
Detailed explanation-3: -By installing renewable energy units like solar panels and solar heaters across the city in private and public buildings over five years, the city aims to slash carbon emissions by 2 million tons to improve air quality in Mexico City.
Detailed explanation-4: -Serious environmental problems persist, including the provision of clean water, air pollution in Mexico City, and rural deforestation and erosion.
