Air pollution is a global issue, with 99% of people worldwide breathing unsafe air

Air pollution is a pressing global issue that affects almost everyone on the planet. According to the World Health Organization (WHO), 99% of people worldwide breathe air that exceeds the recommended guideline limits and contains unsafe levels of pollutants. This means that nearly everyone on Earth is exposed to poor air quality, which has significant implications for both health and the environment.

The sources of air pollution are diverse and varied, including household combustion devices, motor vehicles, industrial facilities, and forest fires. These sources release a range of harmful pollutants, such as particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide. The impact of these pollutants on human health is profound, with outdoor and indoor air pollution causing respiratory and other diseases, contributing to morbidity and mortality. It is estimated that around 7 million people die prematurely each year due to exposure to fine particles in polluted air, which penetrate deep into the lungs and the cardiovascular system.

The issue of air pollution is particularly acute in low- and middle-income countries, where the highest exposures to pollutants are found. Within these countries, vulnerable populations such as women, children, and older adults bear the brunt of the health impacts of air pollution. Additionally, over 3 billion people, primarily women and children, are exposed to deadly smoke in their homes due to the use of polluting stoves and fuels. This disparity highlights the inequitable distribution of the burden of air pollution, disproportionately affecting those who are already marginalized.

Advocacy for air quality and the reduction of air pollution is crucial to address this global health crisis. Organizations such as the World Heart Federation (WHF) and the American Lung Association are leading the charge, advocating for policies and investments that support cleaner air. The WHF's Air Pollution Policy Brief emphasizes the need for a multi-system and multi-sectoral response, including cleaner transport, energy-efficient homes, industry regulation, and better waste management. Additionally, health care providers can play a vital role in advocating for air pollution mitigation, providing patients with guidance on reducing exposures, and integrating air pollution considerations into disease management approaches.

Furthermore, global initiatives such as BreatheLife, a partnership between WHO, UN Environment, and the Climate and Clean Air Coalition, aim to increase awareness and encourage governments and individuals to take action. Through campaigns such as "Marathon a Month," which encourages people to leave their cars behind and opt for alternative forms of transportation, small individual actions can collectively make a significant impact on reducing air pollution. Addressing air pollution is not just a health imperative but also offers a "win-win" strategy for the planet, as many of the drivers of air pollution, such as the combustion of fossil fuels, are also sources of greenhouse gas emissions.

Advocacy for air quality has a history, with organisations like the American Lung Association leading the way

Advocacy for air quality is a crucial global movement, with organisations like the American Lung Association leading the way. For over two decades, the American Lung Association has been a prominent voice advocating for healthy air. Their primary tool is advocacy, aiming to influence public policy and ensure the enforcement of laws and regulations designed to improve air quality.

The association has been instrumental in raising awareness about the dangers of air pollution, which affects 99% of the global population. Through initiatives like the annual "State of the Air" report, they provide a trusted assessment of air quality across the United States. This report utilises data from official air quality monitors and satellite imaging to expose unhealthy levels of fine particle pollution, especially in communities lacking air quality monitors.

The American Lung Association also lobbies governmental bodies, such as the U.S. Environmental Protection Agency, to strengthen emission rules and address the public health risks posed by air pollution. They encourage individuals to share their stories about how air pollution has impacted their health, helping policymakers understand the urgency of the issue. Additionally, they offer science-based information and practical tips to help people improve their indoor air quality, recognising that indoor air pollution from burning fossil fuels also contributes to the problem.

The association's efforts extend beyond advocacy, as they also actively work to improve lung health and educate people about the dangers of air pollution. They have a community of Health Professionals for Clean Air and Climate Action, and they encourage healthcare professionals to join their cause. The association also provides updates and resources to over 700,000 people interested in lung health, including research, inspiring stories, and lung health education.

The work of the American Lung Association has been instrumental in the progress made towards cleaning up air pollution in the United States. Their advocacy has helped enact strong clean air laws, although they recognise the ongoing challenges posed by climate change and the need to defend and strengthen these policies.

Air pollution has serious health impacts, including respiratory and cardiovascular issues

Air pollution is a mix of hazardous substances from both human-made and natural sources. It is a major threat to global health and prosperity, with 99% of people worldwide breathing unsafe air.

In Colombia, for example, a person dies from air pollution-related diseases every 50 minutes.

The main pathway of exposure to air pollution is through the respiratory tract. Pollutants such as fine particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulphur dioxide can penetrate deep into the lungs and enter the bloodstream, causing systemic damage to tissues and cells. Short-term exposure to high levels of particulate matter can lead to reduced lung function, respiratory infections, and aggravated asthma.

Long-term exposure to air pollution increases the risk of developing various diseases, including respiratory issues and cardiovascular issues. This includes an increased risk of lung cancer, heart disease, stroke, chronic obstructive pulmonary disease (COPD), and asthma. Maternal exposure to air pollution is also associated with adverse birth outcomes, such as low birth weight, pre-term birth, and small for gestational age births.

The health impacts of air pollution are not evenly distributed, with certain populations being more vulnerable to its effects. Children, the elderly, pregnant women, and people with underlying health conditions are more susceptible to air pollution-related diseases. Additionally, people of color and those living in low-income urban areas tend to be disproportionately affected by air pollution.

Given the serious health impacts of air pollution, advocacy and action are crucial. Organizations like the World Heart Federation (WHF) and the American Lung Association are leading voices in advocating for clean air and influencing public policy. They work to reduce air pollution through partnerships, education, and the development of clinical guidelines. Individuals, such as Kianni, who joined the American Lung Association as their first climate activist advisor, and Daly, the National Director of El Derecho a No Obedecer in Colombia, are also making significant contributions to the fight against air pollution through their organizations and campaigns.

Education and communication are key to raising awareness and promoting behaviour change

Air pollution is a pressing issue that affects people worldwide. According to the World Heart Federation, over 30% of CVD deaths globally are attributable to air pollution.
