Introduction

Air quality refers to the composition of various gases and particles present in the atmosphere. The key factors that determine air quality include. Particulate matter refers to tiny solid or liquid particles suspended in the air. PM2.5 (particles with a diameter of 2.5 micrometers or less) and PM10 (particles with a diameter of 10 micrometers or less) are of particular concern as they can penetrate deep into the respiratory system and even enter the bloodstream [1].

Literature Review

Ground-level ozone is a secondary pollutant formed when pollutants emitted by vehicles, industrial facilities and other sources react with sunlight. It can exacerbate respiratory conditions and lead to breathing difficulties. These are gases released from combustion processes, mainly from vehicles and power plants. Prolonged exposure to these gases can harm the respiratory system and aggravate lung diseases. VOCs are emitted from various sources, including paints, cleaning products and vegetation. They contribute to the formation of ground-level ozone and particulate matter and can cause both short-term and long-term health effects. The atmosphere acts as a shield, protecting the Earth from harmful solar radiation and regulating its temperature. However, human activities have led to an increase in greenhouse gas emissions, such as carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). These gases trap heat in the atmosphere, leading to global warming and climate change [2].

The burning of fossil fuels (coal, oil and natural gas) for energy, transportation and industrial processes releases significant amounts of CO₂ and other greenhouse gases into the atmosphere. Deforestation and certain agricultural practices also contribute to increased greenhouse gas concentrations. Rapid industrial growth and urban development have led to a substantial rise in greenhouse gas emissions, as well as changes in land use that affect the Earth's natural carbon storage capacity. Methane emissions from livestock, rice paddies and agricultural practices are significant contributors to greenhouse gas concentrations. Global average temperatures have been steadily increasing, resulting in heatwaves and rising sea surface temperatures, leading to the melting of polar ice caps and glaciers. Climate change is linked to an increase in the frequency and intensity of extreme weather events such as hurricanes, droughts, floods and wildfires. Melting ice and the thermal expansion of seawater due to warming contribute to rising sea levels, posing a threat to coastal communities and ecosystems. Many plant and animal species are at risk of extinction due to changing climate conditions, loss of habitat and disrupted ecological relationships. Changes in temperature and precipitation patterns can impact crop yields and food production, leading to food insecurity in vulnerable regions [3,4].

Discussion

Climate change influences the spread of diseases, affects air and water quality and intensifies heat-related health problems. Climate change is one of the most critical issues facing humanity and the planet. Its impacts are wide-ranging and pose significant challenges to the environment, human health and global socioeconomic systems. Urgent and coordinated actions at the individual, national and international levels are essential to mitigate greenhouse gas emissions, adapt to changing conditions and secure a sustainable future for generations to come. The choices we make today will shape the climate of tomorrow and addressing climate change is not just a necessity, it is a moral imperative for the well-being of the planet and all its inhabitants. Climate change, in turn, affects air quality through various mechanisms. Rising temperatures can exacerbate the formation of ground-level ozone, as high temperatures and sunlight promote the chemical reactions that produce it. Changes in weather patterns can also influence the dispersion and transport of air pollutants, affecting the distribution of pollutants over different regions. The health effects of poor air quality are widespread and diverse. Short-term exposure to high levels of air pollution can cause immediate health problems such as irritation of the eyes, nose and throat, coughing and shortness of breath. Long-term exposure to polluted air, however, is associated with more severe health issues. Poor air quality worsens respiratory conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD) and bronchitis. Children, the elderly and individuals with pre-existing respiratory problems are particularly vulnerable [5].

Air pollution is linked to an increased risk of heart attacks, strokes and other cardiovascular diseases. Particulate matter and certain gases can enter the bloodstream, leading to systemic inflammation and vascular damage. Emerging research suggests that air pollution may also have adverse effects on the nervous system, potentially contributing to cognitive decline and neurological disorders. In some regions, the impact of air pollution on health is so severe that it contributes to premature mortality, reducing life expectancy in affected populations. To combat the negative effects of air pollution on human health and the atmosphere, concerted efforts are required at various levels. Governments need to enact and enforce stringent air quality standards and regulations. This includes promoting cleaner technologies, reducing emissions from industrial sources and vehicles and encouraging the use of renewable energy. Raising awareness about air quality issues is essential for fostering individual and community action. People need to understand the risks associated with poor air quality and take measures to protect themselves. Continued research and investment in green technologies and sustainable practices can help mitigate air pollution and its impacts on both health and the atmosphere. Air pollution knows no borders and global efforts are necessary to address transboundary pollution and its consequences [6].

Conclusion

Air quality, the atmosphere and human health are deeply interconnected. The health implications of poor air quality are profound and far-reaching, affecting millions of people worldwide. By prioritizing clean air policies, adopting sustainable practices and promoting global cooperation, we can work towards a healthier future for both the environment and ourselves. Taking action today is not just a matter of improving air quality; it's an investment in the well-being of current and future generations.
