Lorenzo Rojas-Bracho is a Mexican biologist who’s braved poachers and cartels in a quest to save the world’s most endangered marine mammal - a tiny porpoise known as vaquita. There’s only a handful left in the world and their survival is in large part due to Lorenzo's efforts. His work with the animal has earned him the nickname ‘Mr Vaquita’.

Jo Fidgen caught up with Lorenzo to name him one of the winners of BBC Inspirations 2020. For full details of the awards and Covid-19 related changes, please check the revised terms on our website: www.bbcworldservice.com/inspirations.
