THE NEXT PEA SOUP?
It’s bad news for other aquatic wildlife because it starves it of oxygen, but could duckweed on our canals become a new superfood for humans? It certainly grows quickly in the summer – in just one week in July, the Canal & River Trust removed over 70 tonnes from London’s canals – and the weed is grown and eaten in south-east Asia. But although CRT waterway operative Tim Mulligan, working the weedboat, jokingly suggested “it could be the next superfood craze”, the Wellcome Trust, which is researching the plant, says it is grown in very different environments in Asia and people in the UK shouldn’t just help themselves from their local canal. Mr Mulligan added that canal users should also watch that their dogs don’t mistake it for grass and try to walk on the weed.
