John Castle, the Liberal Democrats candidate for the upcoming Princes Park by-election believes that we can no longer ignore the reality, that Medway is no longer free from dirty air. We feel that air pollution must be tackled now, not only to save our environment but to save lives. A report produced by the Centre for Cities found that 1 in 16 deaths in Chatham "are exclusively driven by combustion in commercial, institutional, and domestic activities linked to long-term exposure to particulates." Nationally, Liberal Democrats are calling for World Health Organisation (WHO) guidelines on particulate matter to be adopted into UK law, and met by 2030.
