Air pollution is a major environmental risk to health, and has been receiving increased media coverage in recent months. Research by King’s College London estimated that it contributed to around 9,500 deaths a year in London in 2010, and it has been proven to cause illnesses ranging from eczema and itchy eyes to cancer and lung disease.
