Pick of the week
Should western students and tourists keep out of the Amazon basin? This week's offering in C4's To the Ends of the Earth series (Monday 8.00), which follows an expedition by Royal Holloway College students to Ecuador, does not offer a simple answer. The students want to study the potential impact of eco-tourism on the remote Huaorani tribe, but they find an American researcher already established there. Neither she nor the Huaoranis (or indeed John Groom, the ex-Marine survival expert with the expedition) seem happy with their British visitors' behaviour.
