The broadcaster has created a profile in order to communicate about the dangers of climate change.
His Instagram account will also be used to share stories from Attenborough and the team behind his documentary, A Life On Our Planet.
To mark his arrival on the platform, Attenborough posted a video of himself explaining why he is “exploring this new way of communicating”.
“As we all know, the world is in trouble. 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.
“But we know what to do about it. That’s why I’m tackling this new way, for me, of communication.
“Over the next few weeks I’ll be recording messages to explain what the problems are and how we can deal with them.
“Join me or, as we used to say in those early days of radio, stay tuned.”

Thankfully for Attenborough, he won’t suddenly need to learn how to be social media savvy in his 90s – the account is managed by the filmmakers behind A Life On Our Planet.
But with 2 million followers and counting already, it looks like Attenborough is well on the way to being one of the platform’s most successful influencers!
