Why do we care about some more than others? And what can we do to protect at-risk species? This is The Overview. Presented by Julia O’Driscoll, with guests environmentalist and broadcaster Chris Baines, Dr Nick Isaac from the UK Centre for Ecology and Hydrology, Dr Erica McAlister, senior curator at the Natural History Museum, and Professor Seirian Sumner from UCL.
