The legend that is Sir David Attenborough has joined Instagram.

His official bio describes that the profile will share "stories from David Attenborough and the team behind 'A Life On Our Planet'."

So far his Instagram has just a single post - a video that is just over a minute long.

In it, he explains his reasons for joining the social media platform.

"I am making this move, and exploring this new way of communication for me, because, as we all know, the world is in trouble," he says.

"Continents are on fire. Glaciers are melting. Coral reefs are dying. Fish are disappearing from our oceans. The list goes on and on."

He says that he'll be explaining "what the problems are and how we can deal with them" in the coming weeks.

 

Within an hour of his first post, the veteran broadcaster gained more than 200,000 followers.

At the time of writing, the broadcaster and natural historian is close to 1m followers.
