[Interview starts at 39 10] Fearnley-Whittingstall asked Brown, and her colleague, what impact intensive krill fishing would have on penguin populations in the southern Atlantic, and whether marine protection zones would help to protect bird species reliant on krill.
Rapid and repeated movement between reefs and protection zones suggest that small protective zones such as those within the Ribbon Reefs may only be partially successful in sheltering C. amblyrhynchos from fishing pressure.
"Creating large-scale flood protection zones is expensive and in itself potentially harmful to the environment.
The foreign office said it would designate two further marine protection zones, one each around two south Altantic islands – Ascension by 2019 and Tristan da Cunha by 2020.
Conservationists responded by relocating the country's remaining animals into relatively small "intensive protection" zones, after which poaching took off in South Africa.
He said the fishing industry would benefit from large-scale protection zones where bottom trawling was outlawed but fishing with fixed nets, pots and lines was allowed.
It will emphasise its wish to prevent dumping of dredge spoils on or near the reef rather than having protection zones as per the current plan.
In addition, dozens of natural protection zones have been set up in the province to provide refuge for those endangered species.
In these more fluid diplomatic circumstances there could be a role for protection zones or, perhaps most interestingly – not a no-fly zone – but a no-bombing zone.
The White House should also work with allies and humanitarian workers, such as the Red Cross or Red Crescent, to set up protection zones that are weapons-free safe areas for fleeing refugees along Syria's borders.
But these results demonstrate that protection zones do benefit a broad range of species, and governments must continue to recognise and support them, said Dr Jörn Scharlemann, from the University of Sussex.
