Policy at the crossroads: climate change and injury control

Abstract
Two hundred years ago London was a cesspit. The streets were awash with sewage, and London stank. By July 1858 the smell from the Thames at Westminster was so strong that Parliamentarians concluded that the House of Commons was “unusable.”1 Infectious disease was a deadly scourge, but it was the “great stink” of 1858 that helped secure the £3.5 million needed to sort out London’s sewage. The engineer Joseph Bazalgette was commissioned to design and build an elaborate system for the disposal of London’s sewage.1 Policy on sewage disposal did more to improve the health of Londoners than any health policy that century. Despite erroneous theories of infectious disease causation, environmental public health measures, in particular new sewage disposal and water supply systems, revolutionized public health in Europe.2
