With only a few hours left of this year's Glastonbury festival, it's only fitting that one of the most eagerly awaited appearances of the weekend came from legendary TV presenter and naturalist Sir David Attenborough.

The Pyramid Stage, fresh from The Killers performance last night, was host to Attenborough who spoke to the crowd about our use of plastic and praised organisers for banning it at this year's festival.

“There was one sequence from 'Blue Planet 2' which every seems to remember,” said Sir David. “It showed what plastic has done to the creatures that live in the ocean. It had an extraordinary effect and now this great festival has gone plastic free.”

“That is more than a million bottles of water which have not been drunk by you in plastic. Thank you, thank you! The oceans cover two thirds of this planet of ours. There’s one third which we occupy all the time, the land which only covers only one third of the globe.”

Sir David then announced a new show he's been working on.

“Seven Worlds, One Planet will resonate with audiences worldwide,” said Attenborough. “We all belong to a continent after all, we all share planet Earth.”

Tonight is the last night of the festival and will see performances from The Cure, Kylie and Vampire Weekend.
