A wooded park can filter out 85% of air pollutants and a street lined with trees up to 70%. People who live within 500 m of a quality green space are 24% more active. Increasing exercise levels of just 1 per cent of the UK’s population would save lives and deliver nearly £1.5bn in health care savings. In heat-waves urban greening can cool the city, while green roofs slow down the run-off of stormwater into overburdened drainage systems. Source: Natural England, 3 November 2009
