Giant fish-shaped water ‘zorbs’ rolled into St Katharine Docks to raise public awareness to help stop pollution in the Thames from throwaway packaging and ciggy butts.

The zorbs were manoeuvred across the docks to highlight the harm to marine life from litter in the streets that find their way into the water—300 tonnes are retrieved along the foreshore every year.

The campaign led by Hubbub environmental charity, backed by the Port of London Authority, shows how drink cans left on walls or rubbish dropped down drains end up in the river. Litter breaks down and is being eaten by and harming wildlife. These include train tickets, food wrappers, disposable crockery and cigarette butts which are less likely to make it into a bin.

Most Londoners think the Thames is “too polluted for fish to survive” , the charity points out—yet there are 125 species calling the Thames their home which it says needs protecting.
