The 94-year-old natural historian briefly joined the photo-sharing platform in 2020, but he's no longer on Instagram and he isn't planning to make a return.

The iconic broadcaster said: "I’m so old I can’t get used to all these new media but I was persuaded to do so in order to do a message about conservation. So for a limited period of time I contributed to Instagram but I’m off now. I’m not on it anymore and I don’t intend to go back.

"I’ve got enough problems with post. I get 70 letters a day! I do my very best [to respond to them all]. Sometimes people, mercifully, don’t actually put their address on because people are so unaccustomed to sending letters."

David has recently lamented the lack of international cooperation on the issue of climate change.

The TV star acknowledges that it's a "global issue", but he also insisted "there are lots of things we can do".

He told 'Radio 1 Breakfast with Greg James': "It's difficult, isn’t it, because it’s a global problem that needs global solutions.

"But there are lots of things we can do, and I think one of the best mottos you can have is don’t waste things. Don’t waste food. Don’t waste electricity, don’t waste gas, don’t waste paper.

"All those things make demands on the planet and if we all lived more economically the world would be a much better place."

David recently claimed that 2021 represents a crucial year in the fight against climate change.

He said: "It has been a challenging few months for many of us, but the reaction to these extraordinary times has proved that when we work together, there is no limit to what we can accomplish."
