Thungyai-Huai Kha Khaeng Wildlife Sanctuaries (Thailand) - This jungle, which is protected by forest rangers, is inhabited by rare animals such as green peafowl and Indian elephants. Thungyai and Huai Kha Khaeng are nature reserves that are situated adjacent to each other in a mountainous region in western Thailand. As they share the same environment, they were designated together as a single World Heritage Site. They make up Southeast Asia's largest nature reserve and are inhabited by elephants and tigers. Squads of forest rangers work to prevent poaching in the sanctuaries. Galapagos Islands (Ecuador) - Charles Darwin was amazed by the unusual flora and fauna of the Galapagos Islands group, which includes such animals as giant tortoises and iguanas. Galapagos was the birthplace of the Theory of Evolution. The Galapagos Islands (Galapagos means tortoise) are a group of volcanic islands that belong to Ecuador in South America. They are located in the Pacific Ocean 960 kilometers to the west of Ecuador. They are officially called the 'Archipelago de Colon.' As they are situated in a location that is isolated from the outside world, the islands are inhabited by many unique plants and animals. Correction: Charles Darwin arrived in the Galapagos on the H.M.S. Beagle in 1835, not 1885 as stated in the program.
