Simon Reeve makes another trip around the world, like in Tropic of Capricorn, but now in the Northern hemisphere, along the Tropic of Cancer. Simon thus visits Mexico, the Caribean, Northern Africa, Arabia, India, Bangla Desh, Burma, Laos, Vietnam, Taiwan and Hawai. Local conditions, people, wildlife, history, culture, politics, ecology prove quite varied.—KGF Vissers
