Indonesia’s Leuser Ecosystem is one of the few places where tigers, orangutans, elephants and rhinoceros all live in the wild. But there has been talk of possible development of the area for geothermal energy -- heat that comes from the Earth. Wildlife activists are worried about the plan. Rudi Putra is an adviser at the Leuser Conservation Forum. He asked, “Why do they want to build it inside Aceh’s best remaining forest?” He believes that if the plan is approved, the area “will lose many, many animals.” The Leuser ecosystem is in Aceh, Indonesia’s westernmost province. Last month, the provincial governor asked the central government to change zoning laws for 8,000 hectares of the ecosystem to permit geothermal exploration. Under the plan, a Turkish company would explore part of the 800,000 hectare Gunnung Leuser National Park. The United Nations’ Educational, Scientific and Cultural Organization (UNESCO) has declared the park a World Heritage site.
