A ten-metre whale made entirely of plastic has been unveiled near Tower Bridge to raise awareness about ocean pollution.
The huge marine mammal has been covered with the same amount of plastic that pollutes the ocean every second.
Explorer Sir Ranulph Fiennes and model Jodie Kidd helped reveal the 33ft creation on the south of the river, near City Hall.
Sir Ranulph said: "I've explored some of the most remote and vast points of the world and yet still witnessed the reach of ocean pollution.
"Between 1979 and 1982 my team completed the first surface circumpolar navigation of Earth and during both the Atlantic and the Pacific voyages we witnessed the amount of pollution, much of which was plastic and that was just on the surface.
"It is vital that we all take action to protect our oceans and we must act now before the scale of this problem heightens further."
Kidd said: "There is nothing I enjoy more than being on or by the water - sailing, rowing, on holiday - and it terrifies me that our beautiful oceans are being destroyed.
"As a mother I want my son to grow up in a world where oceans are vast and beautiful, not damaged and under threat.
"It is vital that we all make changes, even in the smallest of ways, to help save our oceans."
The Sky Ocean Rescue campaign, which will see the whale tour cities and coastal spots including Cardiff, Blackpool Promenade and Edinburgh's Ocean Terminal, is being supported by the Marine Conservation Society.
