The World Health Organization (WHO) has cautioned that air pollution is significantly more damaging than previously thought, as it reduces the maximum permissible levels of important pollutants like nitrogen dioxide. According to the World Health Organization, air pollution is on par with smoking and bad eating. Prior to the COP26 session in November, it is asking its 194 member states to reduce emissions and take action on climate change. The limits for what is considered an acceptable quantity of pollution are being lowered decade by decade.

Toxic particles and gases can injure humans at considerably lower levels than previously assumed, which is not news to people with heart and lung problems. As a result of the adjustments, the UK’s regulatory limits for the most dangerous pollutants are now four times higher than the WHO’s maximum levels. The problem is that the worst pollution – microscopic particles that can enter the lungs – is extremely difficult to eradicate. Vehicle emissions and gas central heating contributes to pollution. However, dangerous particles are released into the air in other ways – or are created in the air as a result of chemical reactions.

If you live in a city, you will find it difficult to avoid pollution no matter how hard you try. Heart disease and stroke have been related to pollution in the air. It can stunt a child’s lung growth and exacerbate asthma. “Improving air quality can help with climate change mitigation efforts while cutting emissions will help with air quality,” according to the WHO.
