Air pollution is all around us. Indoors, outdoors, in cities và in the countryside. It affects us all, whether we realize it or not. For the longest time, we have taken the air we breathe for granted. There was air, there were smells, there was cold wind, there was hot air.

But recent research has started to shed light on some rather worrisome aspects of what the air around us really contains, & how it affects our bodies. Và the more we learn, the more we come khổng lồ realize that this essential source of life for the planet needs some serious taking care of. Without air there can be no life but breathing polluted air condemns us khổng lồ a life of disease & early death.

Now that we know how air pollution harms us, there is no excuse not to act. Below are five great reasons lớn reduce and eliminate air pollution from our lives.

Polluted air is creating a health emergency

There is no doubt today that air pollution is a global public health emergency. It threatens everyone from unborn babies to lớn children walking to school, khổng lồ women cooking over open fires.

On the street & inside the house, the sources of air pollution can be very different, yet their effects are equally deadly: asthma, other respiratory illnesses & heart disease are among the adverse health effects known khổng lồ be caused by polluted air.

According to lớn the World Health Organization, every year around 7 million premature deaths are attributable khổng lồ air pollution—a staggering 800 people every hour or 13 every minute. Overall, air pollution is responsible for more deaths than many other risk factors, including malnutrition, alcohol use và physical inactivity.

Children are most at risk

Globally, 93 per cent of all children breathe air that contains higher concentrations of pollutants than the World Health Organization (WHO) considers safe lớn human health. As a result, 600,000 children die prematurely each year because of air pollution. As if that were not enough, exposure khổng lồ dirty air also harms brain development, leading lớn cognitive and motor impairments, while at the same time putting children at greater risk for chronic disease later in life.

Household air pollution is particularly harmful to women & children due to their traditional home-based roles in many cultures. About 60 per cent of household air pollution-related deaths globally are among women và children, & more than half of all pneumonia deaths in children under five can be attributed to lớn indoor air pollution.

Pollution và poverty go hand in hand

Air pollution goes khổng lồ the heart of social justice và global inequality, disproportionately affecting poor people.

In homes, air pollution comes mostly from fuels and high-emitting heating và cooking systems. Clean cooking & heating fuels and technologies are out of reach for low-income families, so polluting alternatives are the norm. About 3 billion people depend on burning solid fuels or kerosene to lớn meet household energy needs và 3.8 million of them will die each year from exposure to these pollutants. A lack of awareness of the risks associated with breathing polluted air also contributes khổng lồ the problem, as well as the cost and difficulty lớn access healthcare.

Crowded cities and trafficked suburbs are hotspots for outdoor air pollution. According to the World Health Organization, 97 per cent of cities in low- và middle-income countries with more than 100,000 inhabitants vị not meet the minimum air quality levels. Around 4 million of the approximately 7 million people who die from air pollution-related diseases every year live in the Asia-Pacific region.

In high-income countries, 29 per cent of cities fall short of meeting the organization’s guidelines. But in those countries, too, poorer communities are often those most exposed—power plants, factories, incinerators và busy roads are often located in or near poor suburban communities.

The cheaper the fuels, the higher the costs

When people get sick, the entire community suffers. Ill people require medical care và medicine, children skip school & working adults miss days of work, either as a result of their own poor health, or to care for a loved one. According lớn the World Bank, air pollution costs the global economy more than US$5 trillion every year in welfare costs & $225 billion in lost income.

A năm nhâm thìn study by the Organisation for Economic Cooperation and Development predicts that, if the situation remains unchanged, by 2060 the annual global welfare costs of premature deaths from outdoor air pollution would be US$18-25 trillion, with the costs of pain & suffering from illness estimated at around US$2.2 trillion.

There are other less direct costs, which nonetheless affect us globally. Ground-level ozone is expected to reduce staple crop yields by 26 per cent by 2030, creating food security & nutrition challenges. Air pollution also degrades materials và coatings, decreasing their useful life & generating costs for cleaning, repair và replacement.

UN Environment’s sixth Global Environment Outlook estimates that climate mitigation actions for achieving the Paris Agreement targets would cost about US$22 trillion. Meanwhile, by reducing air pollution, we could save US$54 trillion in combined health benefits. The math is clear: acting now against air pollution translates into saving US$32 trillion.

The right khổng lồ clean air is a human right

The right khổng lồ a healthy environment enjoys constitutional status—the strongest form of legal protection available—in more than 100 countries. At least 155 states are legally obligated, through treaties, constitutions & legislation, khổng lồ respect, protect và fulfil the right khổng lồ a healthy environment.

The right to lớn clean air is also embedded in the Universal Declaration of Human Rights và the International Covenant on Economic, Social và Cultural Rights, and fully enshrined in the Sustainable Development Goals—the global blueprint for peace & prosperity.
