It is a global public health emergency, threatening everyone from unborn babies to children walking to school, to women cooking over open fires. According to the World Health Organization (WHO), 99% of people worldwide breathe air that exceeds the recommended guideline limits for pollutants. This means that nearly everyone on the planet is exposed to harmful levels of air pollution, whether they are indoors or outdoors, in cities or the countryside.
In cities, air pollution is a significant issue due to crowded conditions and heavy traffic. Power plants, factories, incinerators, and busy roads are often located in or near poor suburban communities, exposing residents to high levels of pollution. Outdoor air pollution in cities can come from various sources, including cars, trucks, factories, power plants, and incinerators, which release pollutants such as smog, soot, and greenhouse gases into the atmosphere. These pollutants can irritate the eyes and throat and damage the lungs, especially in children, the elderly, and people with asthma or allergies.
In rural areas, air pollution may come from different sources, such as agricultural practices and industrial facilities. Even in the countryside, far from busy roads and factories, air pollution can still have detrimental effects on people's health. For example, outdoor labourers, including migrant and seasonal farmworkers, are among the most vulnerable to air pollution. They are exposed to pollutants from various sources, including agricultural activities and nearby industrial facilities. Additionally, rural areas may have higher rates of indoor air pollution due to the use of inefficient and polluting fuels for cooking and heating, such as solid fuels or kerosene.
Indoor air pollution is a significant issue worldwide, affecting people in both cities and rural areas. It is caused by the use of inefficient and polluting fuels and technologies in the home, such as open fires or inefficient stoves fuelled by kerosene, biomass, or coal. Women and children, who typically spend the most time near the domestic hearth, bear the greatest health burden from indoor air pollution. Exposure to indoor air pollution can lead to various health issues, including respiratory illnesses, heart disease, and non-communicable diseases such as stroke, ischaemic heart disease, chronic obstructive pulmonary disease (COPD), and lung cancer.
Overall, air pollution has severe consequences for everyone, regardless of their location. It affects people's health, well-being, and economic productivity, and it is essential to address this issue to protect the planet and the health of all its inhabitants.

It is linked to respiratory and heart issues, strokes, lung cancer, and other diseases
Air pollution is a global public health emergency that affects us indoors and outdoors, in cities and in the countryside. It is linked to respiratory and heart issues, strokes, lung cancer, and other diseases.
Fine particles from air pollution can enter deep into the lungs and are linked to lung cancer. Particle pollution increases the risk of dying early, heart disease, and asthma attacks, and it can interfere with the growth and function of the lungs. In 2013, an 8-year-old girl in China was diagnosed with lung cancer, and her doctor attributed her condition to air pollution. The World Health Organization (WHO) International Agency for Research on Cancer reviewed the available science and concluded that particulate matter causes lung cancer.
Air pollution has been linked to an increased risk of cardiovascular events, including heart attacks, coronary syndrome, arrhythmia, heart failure, stroke, and sudden cardiac death, particularly in people with pre-existing heart disease. Fine particulate matter (PM2.5) can increase the risk of these cardiovascular events. Research by the EPA has found that exposure to increased concentrations of PM2.5 over a few hours to weeks can trigger heart attacks and even death. Longer-term exposure can lead to an increased risk of cardiovascular mortality and decreased life expectancy.
In addition to lung cancer and cardiovascular issues, air pollution has been linked to other diseases. According to the World Health Organization, around 7 million premature deaths are attributable to air pollution each year. Globally, 93% of children breathe air with higher pollutant concentrations than what the WHO considers safe, leading to 600,000 premature deaths annually. Exposure to polluted air also harms brain development, leading to cognitive and motor impairments in children. Overall, air pollution is a serious issue that affects people of all ages and contributes to various diseases and early death.
