'Human Activities and the Loss of Natural Resources Essay\r'

'Natural imagerys including dirty word, urine, lumber, mineral and bio miscellanea fuck off been repeatedly unmake approximately the world by servicemans. â€Å"Since 1970, over 600,000 squ atomic number 18 kilometers (232,000 squ be miles) of virago rainforest run through been destroyed” (Butler, 2011). The FAO (Food and market-gardening Organization) estimated that â€Å" dirty erosion carries away a volume of stigma equivalent to wizard metre deep over 200,000 hect ares tout ensemble(prenominal) socio-economic class in the Philippines.” In Asia, where peeing has always been regarded as an abundant resource, per capita availableness declined by 40-60% between 1955 and 1990 (Coleridge, 2006). â€Å"In randomness Africa major conservation areas such as Kruger national park risked losing up to 60% of the species under their protection” (Brown, 2004). Mindful of the spillagees of natural resources, this essay exit talk of how military man act ivities harm the world’s natural resources in terms of the spillage of soil resource, forest resource, and biodiversity.\r\n• The liberation of soil resource\r\nHuman activities have very much led to the issue of soil resources, which are the basis for sustained food security. reason occurs naturally from physical and chemical obliteration of rocks and minerals combined with fossil. Be stool of such a combination, soil has different properties. Nowadays humane activities repeatedly destroy soil resource. For example, vile put down degrades soil quality. It is easy for wind and water to bring fertile soil away, which ultimately results to soil erosion. The FAO (Food and Agriculture Organization, a secern of United Nations) estimates that â€Å"the global departure of reproductive land through erosion is 5-7 cardinal ha/year.” another(prenominal) example of the loss of soil resource is farmers’ lack of experience (à¸à¸±à¸¨à¸™à¸µ ยà¹Å' อัà¸à¸à¸°à¸™à¸±à¸™à¸à¸™à¹Å', 2554). These farmers will not know and so how to prepare soil for cultivation. That is why the soil quality is damaged. WRI, UNEP, UNDP, and World Bank have found that â€Å"the degradation of soil resources all over the world is 1.9 billion hectares.” both examples show that human activities cause the loss of soil resource.\r\n• The loss of forest resource\r\n sets, which are valuable asset and all-important(a) resource on human race, have been destroyed by human activities. â€Å"Nearly 4 billion hectares of forest cover the body politic’s sur human face, roughly 30 percent of its total land area” (Mygatt, 2006). in that location are many tree and zoology species in the forest, so forests contain a lot of beneficial things for humans. Many human activities destroy the forest area. For example, people frequently cut down the trees and use the woodwind for trade, fuel, an d furniture. The removal of trees without sufficient reforestation will result to the loss of forest area. â€Å"Forest area decreased worldwide by 0.22% per year in the period 1990-2000 and 0.18% per year between 2000 and 2005” (FAO, 2006).\r\nThis research shows that the world in every year still continues to have the forest area. Another example of human performance is people, especially in develop countries, change the forest area to gardening land and tourist attraction including resorts, museums, and parks. The 2007 report, which snarly more than 1,300 scientists from 95 countries, said that â€Å"every year about 10-million hectares of the world’s forests are lost to unsustainable modes of economic development.” tout ensemble of above are human activities, which cause the loss of forest resource.\r\n• The loss of biodiversity\r\n scorn knowing about biodiversity’s immenseness for a long time, human activity has been causing the loss o f biodiversity. Biodiversity means the diversity of plant and animal life in a particular habitat around the world. Scholar estimates that â€Å"there are 5 million species on the earth, but scarcely 1.9 species are known.” Nevertheless, the numbers of species have been go away by human activities every day. For instance, illegal logging is the greatest cause of species extinction worldwide because tropical forests contain at least half the Earth’s species. Scientists said that â€Å"plant and animal species are now vaporizeing 100 to 1,000 time faster than the natural pace of extinction.”\r\nThis rapid extinction rate makes ecosystem become imbalance. Another example of human activity that causes the loss of biodiversity is hunting. Most people hunt for food, trade, and recreation. This activity also makes the wildlife become extinct rapidly. Statistics data on the loss of biodiversity suggest that â€Å"at least 20% of bird species have already complet ely vanished and that 23% of mammals, 25% of conifers, 32% of amphibians and 52% of cycads continue to face serious threat of extinction.” These are the examples of human activities that lead to the loss of biodiversity.\r\nHuman activities (such as illegal logging, farmers’ lack of knowledge, land clearing, and hunting) are the major causes of the losses of soil resource, forest resource, and biodiversity. People should pay more charge to these problems. They can learn more study about the soil to prevent the loss of soil resource. When they cut down trees, they should not forget to reforest for avoiding the loss of forest resource. They should be more concern and asseverate to the forest area to protect biodiversity, other than plant and animal species on earth may decrease and totally disappear from the earth.\r\n'
