Sir David Attenborough is in Cambridge to celebrate the official opening of a new global conservation hub at the University of Cambridge.
The naturalist who is about to turn ninety, recently abseiled down a 'living wall' on the new building which has been named after him to help promote the hub.
The new conservation initiative will create the largest grouping of nature conservation organisations and researchers in the world.
Called the 'David Attenborough Building', it houses more than 500 conservation experts and 150 academics from seven departments across the University of Cambridge. They will now work together to find solutions to the challenges faced by the natural world.
Cambridge Conservation Initiative has been behind the vision for the 'hub' since 2007.
Sir David Attenborough who is a graduate of the University of Cambridge will officially open the building with a speech.
