Paul Lister: Founder of the European Nature Trust on over population and reintroducing wolves

This week's guest has been ferocious in his determination to make a difference. Often at times controversial, he has sparked the debate on whether to reintroduce wolves to Scotland, he is a 'doer',  whether it is creating awareness of conservation issues in Belize to founding the European Nature Trust or rewinding the Alladale Estate in Scotland, Paul’s extraordinary energy is focused on  his mission to re-connect people with nature for one purpose, getting conservation work done - urgently.
