VOICED : Londres bajo la polucion

A thick smog, not the usual fog, covered London and parts of England, prompting health warnings due to high pollution levels. The smog results from local and European industrial emissions mixed with Saharan dust. Authorities advised asthmatics and vulnerable groups to take precautions. Unlike Paris, London hasn't restricted vehicle use. The UK faces legal action from Europe for failing to reduce nitrogen dioxide levels, mainly from vehicle emissions. According to WHO, air pollution caused seven million deaths globally in 2012.
