Human Activities and the Loss of Natural Resources Essay

Natural resources including primer coat, water, timberland, mineral and biodiversity mother been repeatedly exterminateed around the serviceman by compassionate beings. Since 1970, over 600,000 squ be kilometers (232,000 squ are miles) of Amazon rain woods deliver been destroyed (Butler, 2011). The FAO (Food and Agriculture Organization) estimated that soil erosion carries away a the great unwashed of soil equivalent to one metre deep over 200,000 hectares any year in the Philippines. In Asia, where water has always been regarded as an rampant resource, per capita availability declined by 40-60% between 1955 and 1990 (Coleridge, 2006). In South Africa major saving force fields such as Kruger national park risked losing up to 60% of the species infra their protection (Brown, 2004). Mindful of the mischiefes of natural resources, this essay will talk of how mankind activities harm the worlds natural resources in toll of the loss of soil resource, forest resource, and biodiversity. The loss of soil resource pitying activities have often led to the loss of soil resources, which are the cornerstone for sustained food security. Soil occurs natur altogethery from physical and chemical obliteration of rocks and minerals combined with fossil. Be father of such a combination, soil has different properties. Nowadays human activities repeatedly destroy soil resource. For framework, nefarious logging degrades soil timber. It is user-friendly for wind and water to bring fertile soil away, which eventually results to soil erosion. The FAO (Food and Agriculture Organization, a branch of United Nations) estimates that the global loss of ample land through erosion is 5-7 million ha/year. Another example of the loss of soil resource is farmers lack of knowledge ( , 2554). These farmers will not know indeed how to prepare soil for cultivation. That is why the soil quality is damaged. WRI, UNEP, UNDP, and World Bank have found that the degradation of soil r esources all over the world is 1.9 billion hectares. Both examples show that human activities receive the loss of soil resource. The loss of forest resourceForests, which are priceless asset and essential resource on reason, have been destroyed by human activities. Nearly 4 billion hectares of forest cover the earths surface, roughly 30 percent of its total land flying field (Mygatt, 2006). There are many tree and animal species in the forest, so forests contain a lot of beneficial things for humans. Many human activities destroy the forest area. For example, people often concussion down the trees and use the forest for trade, fuel, and furniture. The removal of trees without sufficient reforestation will result to the loss of forest area. 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).This research shows that the world in every year still continues to lose the forest area. Another example of human activity is people, especially in developing countries, change the forest area to agriculture land and tourist attraction including resorts, museums, and parks. The 2007 report, which involved more than 1,300 scientists from 95 countries, said that every year about 10-million hectares of the worlds forests are lost to unsustainable modes of economic development. All of above are human activities, which cause the loss of forest resource. The loss of biodiversityDespite knowing about biodiversitys importance for a long time, human activity has been causing the loss of biodiversity. Biodiversity means the diversity of plant and animal life in a particular habitat around the world. Scholar estimates that there are 5 million species on the earth, but only 1.9 species are known. Nevertheless, the numbers of species have been disappearing by human activities every day. For instance, illegal logging is the great cause of species extinction worldwide because tropical forests contain at t o the lowest degree half the Earths species. Scientists said that plant and animal species are now disappearing 100 to 1,000 times faster than the natural pacing of extinction.This 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 excessively makes the wildlife become extinct rapidly. Statistics data on the loss of biodiversity suggest that at least 20% of bird species have already completely vanished and that 23% of mammals, 25% of conifers, 32% of amphibians and 52% of cycads continue to face serious terror of extinction. These are the examples of human activities that lead to the loss of biodiversity.Human 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 attention to these pr oblems. They can learn more information 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 conserve to the forest area to protect biodiversity, differently plant and animal species on earth may decrease and solely disappear from the earth.
