Palm oil <=SEP=> Palm oil ( also known as dendê oil , from Portuguese -LSB- ˈdɛnde -RSB- ) is an edible vegetable oil derived from the mesocarp ( reddish pulp ) of the fruit of the oil palms , primarily the African oil palm Elaeis guineensis , and to a lesser extent from the American oil palm Elaeis oleifera and the maripa palm Attalea maripa .   Palm oil is naturally reddish in color because of a high beta-carotene content . It is not to be confused with palm kernel oil derived from the kernel of the same fruit , or coconut oil derived from the kernel of the coconut palm ( Cocos nucifera ) . The differences are in color ( raw palm kernel oil lacks carotenoids and is not red ) , and in saturated fat content : palm mesocarp oil is 49 % saturated , while palm kernel oil and coconut oil are 81 % and 86 % saturated fats , respectively . However , crude red palm oil that has been refined , bleached and deodorized , a common commodity called RBD palm oil , does not contain carotenoids .   Along with coconut oil , palm oil is one of the few highly saturated vegetable fats and is semisolid at room temperature . Palm oil is a common cooking ingredient in the tropical belt of Africa , Southeast Asia and parts of Brazil . Its use in the commercial food industry in other parts of the world is widespread because of its lower cost and the high oxidative stability ( saturation ) of the refined product when used for frying . One source reported that humans consumed an average 17 lb of palm oil per person in 2015 .   The use of palm oil in food products has attracted the concern of environmental activist groups ; the high oil yield of the trees has encouraged wider cultivation , leading to the clearing of forests in parts of Indonesia and Malaysia to make space for oil-palm monoculture . This has resulted in significant acreage losses of the natural habitat of the orangutan , of which both species are endangered ; one species in particular , the Sumatran orangutan , has been listed as critically endangered . In 2004 , an industry group called the Roundtable on Sustainable Palm Oil was formed to work with the palm oil industry to address these concerns . Additionally , in 1992 , in response to concerns about deforestation , the Government of Malaysia pledged to limit the expansion of palm oil plantations by retaining a minimum of half the nation 's land as forest cover .

Deforestation <=SEP=> Deforestation , clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use . Examples of deforestation include conversion of forestland to farms , ranches , or urban use . The most concentrated deforestation occurs in tropical rainforests . About 30 % of Earth 's land surface is covered by forests .   Deforestation occurs for multiple reasons : trees are cut down to be used for building or sold as fuel , ( sometimes in the form of charcoal or timber ) , while cleared land is used as pasture for livestock and plantation . The removal of trees without sufficient reforestation has resulted in damage to habitat , biodiversity loss and aridity . It has adverse impacts on biosequestration of atmospheric carbon dioxide . Deforestation has also been used in war to deprive the enemy of vital resources and cover for its forces . Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and the United States military in Vietnam during the Vietnam War . As of 2005 , net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$ 4,600 . Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland .   Disregard of ascribed value , lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale . In many countries , deforestation , both naturally occurring and human-induced , is an ongoing issue . Deforestation causes extinction , changes to climatic conditions , desertification , and displacement of populations as observed by current conditions and in the past through the fossil record . More than half of all plant and land animal species in the world live in tropical forests .   Between 2000 and 2012 , 2.3 e6sqkm of forests around the world were cut down . As a result of deforestation , only 6.2 e6km2 remain of the original 16 e6km2 of forest that formerly covered the Earth .

Wind turbine <=SEP=> A wind turbine is a device that converts the wind 's kinetic energy into electrical power .   Wind turbines are manufactured in a wide range of vertical and horizontal axis types . The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs . Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid . Arrays of large turbines , known as wind farms , are becoming an increasingly important source of intermittent renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels .
