The former CEO of Singapore Zoo Bernard Harrison is credited for helping transform the zoo into being one of the most successful in Asia with its open concept of animal display.

While he believes many other zoos are in need of improvement, he tells Mishal Husain he is still a passionate supporter of the concept as he believes it brings people closer to animals in a way that would not otherwise be possible.
