The city of London is embroiled in a long-standing battle against air pollution. Are its latest efforts enough, or is it too little too late?
In China, an occupational lung disease called pneumoconiosis is killing three times the number of miners dying from mining accidents. In Burkina Faso—Africa’s fourth-largest producer of gold—entire families toil among hazardous machinery and chemicals as they mine. In the Philippines, the smallest (and youngest) workers shrink down into crevices, risking their lives to carry out underwater compressor mining.
It has long been common knowledge that pollution harms our planet in the long term. But pollution is also a determinant of more immediate health effects, particularly for the world's poorest. As the leading cause of premature deaths around the world, pollution contributes to an estimated one in seven deaths each year, according to the Global Alliance on Health and Pollution. Most of these deaths occur in emerging nations where byproducts of unregulated mining and industrial waste disposal contaminate air, water, soil and ultimately food.
The worst pollutants—lead, mercury, cadmium radium and radioactive isotopes, chromium and pesticides—affect tens of millions of people and are major drivers of chronic diseases and cancers that cut lives short by decades. Air pollution from vehicle exhaust and coal-fired power plants affects millions more in the most congested cities of China, India and Eastern Europe, while indoor charcoal cooking fires are silently killing the poorest of the poor in Africa.
And moreover, consumers seem more complacent than ever to the risks posed by their demands. There are few incentives to foster hazard-free work environments. In fact, whether for our gold jewelry or our advanced electronics, producers need to cut corners in order to provide the goods we want at the prices we like.
This Issues gateway explores the major pollutants and the most polluted sites in the world to examine causes and consequences—and the search for solutions.
