• 🚑 The diseases caused by air pollution include heart disease, stroke, lung cancer, and bronchitis.
• 👶 Vulnerable groups such as infants, young children, adults over 65, and those with pre-existing respiratory conditions are more susceptible to the effects of air pollution.
• 🏙️ Socioeconomic status and racial disparities exist in exposure to polluted air, with African-American communities facing higher premature death rates from particle pollution.
• 🌍 Air pollution is a leading environmental cause of death, with over 7 million deaths attributed to it annually.
• 🛴 Actions individuals can take to reduce air pollution include carpooling, biking, walking, and reducing the use of fossil fuels.
• 🌳 Recognizing the severity of air pollution and taking personal responsibility for reducing one's contribution to it is crucial for the health of both individuals and the planet.
