Air pollution is now the fourth biggest killer in the world after smoking, high blood pressure and diet. It contributes to more than six million deaths every year. The majority of these are in poorer nations. Worryingly, air quality may become increasingly worse with rapidly expanding urbanization.
More than half the world’s population now live in cities. By 2050, this will reach two thirds. As more people move from rural areas to cities, there will be more cars on the roads, more traffic congestion hotspots near homes and workplaces, and less green space.
