London protesters demand water companies clean up sewage-tainted rivers

Organizers estimated that 15,000 people took part in the march along the River Thames to Parliament, many wearing blue and waving blue flags to form a “human river.” The March for Clean Water was organized by groups ranging from Greenpeace and Friends of the Earth to British Rowing. Water pollution has become an increasingly high-profile issue in Britain, focusing attention on climate change and the legacy of privatization of Britain’s utilities several decades ago.
