Air pollution kills how many people per year?

• A. 5 million
• B. 10 million
• C. 8 million
• D. 12 million

Answer: (B)

Global deaths linked to air pollution are driven by long-term exposure to fine particles and harmful gases that raise the risk of heart disease, stroke, COPD, lung cancer, and infections. Because exposure is widespread in both outdoor and indoor environments, the total annual deaths are commonly cited as about ten million. This figure comes from public health assessments that combine data on ambient and household pollution across many countries, and it’s the one often used in practice questions. While estimates can vary with definitions and methods, ten million is a widely used benchmark, making it the best choice among the options.
