CBBC launched a nationwide competition to find a group of children who care passionately about wildlife, giving them the chance to become part of the Saving Planet Earth Challenge Team. The seven lucky winners travel to far-flung corners of the world, spending two weeks in the wild with their favourite animals and reporting on the plights of some of our most endangered species. Adesh Sundarasan, aged 11 from Buckinghamshire, travels to South Africa to look at the plight of the cheetah.
