Air pollution and climate change are closely linked, creating a harmful cycle that affects our health and the planet. A UN report reveals that pollution contributes to about nine million deaths each year. Most of these deaths happen in low- and middle-income countries, where the impact is especially severe.
The Global Environment Outlook-7 (GEO-7) report shows that air pollution, worsened by climate change, is a major threat to human health and ecosystems. This pollution comes from various sources, including transportation, industry, and waste mismanagement. Nearly everyone on Earth experiences some level of air pollution, which can lead to serious health issues.
According to the report, air pollution now includes harmful substances like heavy metals, plastic particles, and greenhouse gases. While some areas, like Western Europe and North America, have seen a decrease in pollutants like sulfur dioxide, other regions, particularly in Asia, continue to struggle with rising levels.
Interestingly, fine particulate matter (PM2.5) has seen improvements in many cities, but places like Delhi and Tehran remain heavily polluted. Festivals, often featuring fireworks, significantly spike pollution levels in countries like India and Mexico. The report also points to unmonitored emissions from landfills as a big problem.
Air pollution is well-known for causing respiratory and heart diseases, but it can also impact our brain health, leading to issues like cognitive decline and increasing risks of conditions such as type-2 diabetes and dementia.
Wildfires, driven by climate change, make this situation worse. As temperatures rise, the risk and intensity of wildfires increase, leading to more pollution and health risks. The World Meteorological Organization indicates global temperatures have risen significantly in recent years, making weather extremes more common.
Moreover, pollution from these fires contributes to further climate issues, completing a dangerous feedback loop. Vulnerable populations, including older adults and those with pre-existing health conditions, are particularly at risk from wildfire smoke.
Experts stress the importance of taking urgent action to combat these challenges. Climate action is not just an environmental issue; it has crucial implications for public health and economies. The costs of inaction are staggering, already running into trillions of dollars annually.
This interconnected crisis highlights the need for cooperative global efforts to improve air quality and address climate change. Together, these steps can protect both our health and the environment.
