The latest series of Channel 4’s ‘The Island With Bear Grylls’ has seen Bear and the contestants slaughter pigs, turkeys and crocodiles.
But Sir David has criticised the killing of animals for the sake of entertainment.
The 91-year-old ‘Blue Planet’ presenter told The Sun: “We’ve never killed an animal.
It’s not the first time Bear has come under fire for sacrificing animals on his show.
Animal charity PETA has also condemned the show’s “miserable celebrities and producers” after Olympian Iwan Thomas and former ‘Coronation Street’ actor Ryan Thomas killed a crocodile with a knife.
The scenes, which aired last year during the celebrity special, also sparked complaints to media watchdog Ofcom.
Meanwhile, following the huge success of ‘Blue Planet 2’, Sir David has signed a huge deal to host a new Netflix show on conservation.
He said: “Netflix want me to do something on conservation and have asked me to do it, and I’ve said I would.
“There’s certain things that the BBC can do and can’t do, and I can see some reasons why to do a programme on Netflix rather than the BBC.”
Earlier this week, Sir David revealed the one thing that could put an end to his 75-year TV career.
