Serious Andes - Episode 5
Eight young adventurers go to extremes to help the planet. The team sees the heart-warming climax of a week of hard labour, as two endangered spectacled bears complete their journey to freedom. They face a massive final challenge, to become the youngest team ever to conquer the mighty volcano Cotopaxi (19,346ft/5,897m). The first leg of the climb proves immensely tough and several of the team fall victim to altitude sickness.
