Abstract

Mankind is increasingly polluting the atmosphere across the planet. The research detailed in this video is interested in the questions of how this pollution is generated and how it affects the health of people. The investigators found, as JOS LELIEVELD explains, that air pollution leads to millions of premature deaths since it causes, for instance, fatal cerebrovascular and respiratory diseases. The researchers also identified a variety of natural and human sources for this pollution, such as ammonia emissions through agriculture in Europe or the widespread use of cooking fires in South East Asia. Their findings indicate means by which air pollution could effectively be reduced worldwide.
