Air Pollution
Jun 26, 2020
Air pollution kills an estimated seven million people worldwide every year. WHO data shows that
9 out of 10 people breathe air containing high levels of pollutants. WHO is working with
countries to monitor air pollution and improve air quality.
From smog hanging over cities to smoke inside the home, air pollution poses a major threat to
health and climate. The combined effects of ambient (outdoor) and household air pollution
cause about seven million premature deaths every year, largely as a result of increased
mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and
acute respiratory infections.

Air pollution leads people to be exposed to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections. Industry, transportation, coal power plants and household solid fuel usage are major contributors to air pollution. Air pollution continues to rise at an alarming rate, and affects economies and people’s quality of life.
