How does air quality affect our health in different cities around the world?

Shawnna Toombs

Air quality is a vital factor that has a direct impact on our health. In different cities around the world, the level of air pollution varies, which ultimately affects the health of its inhabitants. For instance, in cities like Beijing, New Delhi, and Mexico City, the air pollution level is extremely high, which leads to various health issues like respiratory problems, heart diseases, and even cancer.

The impact of air quality on our health varies depending on the concentration of harmful pollutants in the air. Air pollution has both short-term and long-term health effects. Short-term effects include eye irritation, respiratory problems, headaches, and nausea. Long-term exposure to polluted air can lead to severe health issues like heart disease, stroke, and cancer.

In polluted cities like Beijing, the levels of PM 2.5 and PM 10 are alarmingly high. PM 2.5 refers to tiny particles in the air that are smaller than 2.5 micrometers, which can enter our lungs and even bloodstream. PM 10, on the other hand, refers to microscopic particles under 10 micrometers which also affect our lung health. In Delhi, the air quality has hit ‘severe’ levels, and the situation is no different. The increased concentration of pollutants in the air can cause severe health issues.

Furthermore, air pollution can also trigger pre-existing health conditions like asthma and allergies, making them worse for people who suffer from them. In addition, the elderly and young children are more vulnerable to the harmful effects of air pollution, and their health can deteriorate quickly in polluted cities.

To combat the impact of air pollution on our health, the government needs to play a significant role by implementing policies to reduce the pollution levels in cities. Initiatives like planting more trees, promoting electric vehicles, are some of the steps that can help reduce air pollution. Individuals can also contribute to reducing air pollution by using public transportation instead of private vehicles, carpooling, and avoiding burning trash outdoors.

In conclusion, air quality has a significant effect on our health in different cities around the world. High levels of air pollution can cause respiratory problems, heart diseases, and even cancer. It is essential to take steps to reduce the pollution levels by implementing policies and making individual efforts to promote clean air. Only then can we hope to breathe in fresh air and lead healthy lives.
