Often warned by natives that he would die, Ed even found himself pursued by machete-wielding tribesmen and detained for murder. However, Ed's journey was an adventure with a purpose: to help raise people's awareness of environmental issues. Ed had unprecedented access to indigenous communities and witnessed the devastating effects of deforestation first-hand. His story of disappearing tribes and loss of habitats concerns us all. Ultimately though, "Walking the Amazon" is an account of a world-first expedition that takes readers on the most daring journey along the world's greatest river and through the most bio-diverse habitat on earth.
