Air pollution is now one of the greatest external threats to health for urban dwellers. Worldwide it is estimated that three millions people, more than half of them in developing countries, die every year from air pollution. In some cities, it is more dangerous to breath than smoke cigarettes. One of the most dangerous pollutants is nitrogen dioxide which comes from car fumes. Inhaling high levels of nitrogen dioxide can reduce lung capacity, stunt lung growth and reduce life expectancy by up to six months. London has the highest levels of nitrogen dioxide in Europe, and is ahead of Hong Kong and New York. Oxford Street is the most polluted street in Europe and the worst time to be outside breathing in nitrogen dioxide in London? 10am.
