Sir David Attenborough

At 94 years young, the naturalist's follower count raced to seven figures in four hours 44 minutes on Thursday, according to Guinness World Records.

His debut post said: "Saving our planet is now a communications challenge."

Last October, Friends star Aniston reached the milestone in five hours and 16 minutes.

In his first video, the veteran broadcaster told followers: "I am making this move and exploring this new way of communication to me because, as we all know, the world is in trouble.

He sighted BBC video footage of the heavy duty machinery brought in by deep sea miner Nautilus Minerals recently.

He fears the prospect of rare forms of life being wiped out.

 “It’s heart breaking”.

He told the BBC that he is horrified at the idea of the destruction of hydro thermal vents.

“That’s where life began and we shouldn’t be destroying these things, it’s so deeply tragic, I mean that humanity just plough on with no regard for the consequences because they don’t know what they are. “
