David Attenborough at 90: how has he influenced your life?

As David Attenborough turns 90, we'd like you to share how the wildlife television presenter has influenced your life.

To celebrate Sir David Attenborough's 90th birthday on 8 May, we'd like you to share your tributes to the wildlife broadcaster and naturalist whose career in broadcasting has spanned more than half a century.

A twist of fate led Sir David to his first presenting role on the BBC series Zoo Quest in 1954. Since then he has fronted a vast number of wildlife documentaries, collected honorary degrees - 32, which is the most of any other person, and has inspired a huge number of wildlife documentary-makers and enthusiasts.
