Presentations and Interviews

Extinct! BBC Radio 4 (24th May 2012)
Dr. Ben Collen and Dr Monika Böhm were interviewed for the BBC Radio 4 programme “Extinct!”. The programme discussed whether the world is currently entering a sixth great mass extinction as result of habitat destruction and climate change. It asks how far towards this 75% loss of species we have come and whether there is anything that we can do about it.

The Communicate Conference talk (27th October 2008)
Communicate, run by the Bristol Natural History Consortium brings together professional environmental and conservation communicators through an on-line community and annual conference. ‘In the know’ was a session in the 2008 conference, where 3 scientists were invited to bring science communicators up to date with the key scientific issues in conservation.
