The Human Impact On Environment

The Human Impact On EnvironmentIn some pluralitys opinions mans impact on the environment is a big issue in our life which is easily neglected, as humans are responsible for a staggering amount of constipation on the farming. Nature manages its own components.Since the outbreak of technology and industrialisation humans kick in greatly had a negative impact on the environment, such as channelize pollution, habitat destruction, water pollution, the burning of rainforests and primer coat pollution. In this essay I intend to give facts and discuss the effects and ca exercises on these topics and discuss the solutions macrocosm carried out to improve the conditions.Air pollution effects people in areas of emission sources, such as, power plants, local industry and major roadstead. Humans yield to pollution by the use of machinery in industry ca using pollution to the environment. More effects of air pollution on the environment involve using diesel fuel for vehicles and coal fo r power along with the lack of emission controls for vehicles and industry.Another cause of air pollution is the greenhouse gas CO2, this gas warms the earth through living things as they emit CO2 when breathing which contributes to humans also, as we add to this statistic through breathing also. CO2 is usually thought to be involved with cars, aeroplanes and power plants, in the past 150 years , CO2 has been polluting our atmosphere through the sources mentioned, this is the highest CO2 emissions recorded for a long time. More causes of air pollution is methane gas which comes from swamps which are contributed to man through flooding. Cfcs are another major cause of air pollution by man through the use of fridges and deodorants (aerosols) which harms the earths ozone layer.Solutions to Air defilementSolutions to air pollution include driving and flying slight, recycling, and conservation. Governmentsare limitting emissions of carbon dioxide and other greenhouse gases through the K yoto Protocolthis is an agreement between countries that they ordain cut back on carbon dioxide emissions. Another manner being put into practice is to put taxes on carbon emissions or higher taxes on gasoline.( http//environment.nationalgeographic.com/environment/global-warming/pollution-overview.html )Acid RainAcid rain has a big effect on the environment and is caused through men by the emission if normality oxides through road transport, power station and industry, over 2000 tonnes of nitrogen oxide was soil into the air in 1990 along with over 3000 tonnes of sulphur dioxide through power stations and industry. Sulfur dioxide is known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes realm to cool. Another adverse effect of these gases being emitted into the atmosphere by humans is the weathering of buildings, particularly those made from limestone, marble and sandstone. For example sulphate- rich precipitation reacts with limestone and is easily eroded. Many method fuddle been used to reduce the effects of acid rain, one is to add powdered limestone to lakes to increase their pH values, how ever the only real effective and practical solution is to reduce fossil fuel consumption by using alternate energy sources that do not produce nitrate or sulphate gases (hydropower or nuclear power).Water PollutionAsian rivers are the most polluted in the world. They have three times as many bacterium from human surplus as the global average and 20 times more lead than rivers in industrialized countries.Thirty percent of Irelands rivers are polluted with sewerage or fertilizer. The King River is Australias most polluted river, suffering from a severe acidic condition related to mining operations.100, 000 marine mammals, 1 gazillion sea birds and other aquatic lives are killed due to plastic knock off in water and coastal area.Bangladesh has some of the most polluted groundwate r in the world. In this case, the contaminant is arsenic, which occurs naturally in the sediments. Around 85% of the total area of the country has contaminated groundwater, with at least 1.2 million Bangladeshis exposed to arsenic inebriety and with millions more at risk.Pollution of freshwater is a problem for about half of the worlds population. Each year there are about 250 million cases of water-related diseases, with nearly 5 to 10 million deaths.The main problem of water pollution is that it kills life Dead fish, birds, dolphins, and many other animals often wind up on beaches, killed by pollutants.Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.humans are affected by this process as well. deal can get diseases such as hepatitis by eating seafood that has been poisoned.Ecosystems can be se verely changed or destroyed by water pollution. Many areas are now being affected by careless human pollution,Solutions to Water Pollution stabilising wetlands to act as a buffer zone to overflow and to assist in filtering pollutants Drive less to reduce the amount of air pollution being emitted into the environment and minimize the amount of nitrogen deposition. Improve the sewage treatment system to stop the leaks in the pipes. Conserve water Improve storm water management. Monitor watershed Stop deforestation to soak up the rain water and prevent run transfer from occurring.Land PollutionThe human impacts related with land pollution involves the Increase in urbanization as body structure uses up forestland. More constructions means increase in demand for raw materials like timber. This leads to the exploitation and destruction of forests, the Increase in agricultural land As the human population grew there was a greater demand for food. This caused more land allocated to agricu lture. Forests were cut down for this purpose, Agricultural activities Besides domestic waste, pesticides and herbicides used by farmers to increase crop yields also pollute the land when they are washed into the soil and Industrial activities are also a contributing factor to land pollution. For example, in open cast mining, huge holes are dug in the ground and these form dangerously deep mining pools. Heaps of mining waste are left behind and these waste often contain several poisonous substances that exit contaminate the soil.The effects on humans is that the Pollution is plausibly to affect over a billion people around the world, with millions poisoned and killed each year.The World Health Organization estimates that 25 percent of all deaths in the ontogenesis world are directly attributable to environmental factor.Some researchers estimate that exposure to pollution causes 40 percent of deaths annually. Many people are not aware of the impact that such industrial pollution ca n have on the earth. By helping to make it known, you can be one of the voices that will draw attention to the issue thus helping to inspire change.Solutions to Land PollutionNew laws and regulations such as, reduce use of plastic, recycle and reuse have greatly reduced the amount of commercial and industrial pollution,Habitat Destruction/DeforestationHabitat destruction is happening all over the world and proximate to your home than you might think. Tropical rain forests in Central and South America and in Southeast Asia and Oceania are being threatened. Rainforests now occupy less then of the land that they did 100 years ago (thats less than 2% of the earths surface).Humans are a major cause of habitat destruction. The causes include, logging, agriculture, the building of roads and cities, and forest fires. Logging involves Humans cutting down the forests and rain forests for wood and wood products.Usually, only large prime trees are cut down, such as mahogany. However, smaller trees can be destroyed in the process and never replaced. Logging can cause soil erosion, and the logging roads that are reinforced can damage rivers and streams. Agriculture involves Wild lands being cleared for crops and domestic animals. The single biggest cause of deforestation is farming. Animals that are used to living in a biodiverse habitat cannot survive in an area with one crop. Humans impact on habitat destruction is majorly involved in the building of roads and cities, although indispensable for life, this still causes a problem for biodiversity as Humans are clearing trees and wild lands to make room for roads and cities. Cities replace the natural habitat of many species of plants and animals. Highways and freeways can destroy plants and also keep animals from safely travelling through their natural habitat.Recent effects of humans on the environmentHumans have recently had a massive impact on the environment with the nuclear power plant disaster in Japan following th e biggest earthquake/tsunami ever recorded cooling systems failures that led to radioactivity escaping from a reactor at one location. The emergency declarations, which include five reactors at the two plants, followed Fridays 8.9-magnitude earthquake off the countrys northeast coast. In a troubling announcement, Japan Nuclear and Industrial Safety Agency official Ryohei Shiomi said a monitoring device international the plant detected radiation that is eight times higher than normal and an evacuation zone has been expanded from three kilometres around the plant to 10 kilometres.( http//news.slashdot.org/ written report/11/03/12/038218/Nuclear-Emergency-Declared-At-2-Plants-In-Japan?from=rss )The impact this had on the environment was really frightening as fears of people being exposed with radiation which was life threatening and people were even evacuated from their homes and told not to go outside, there is now fears that the food produced there may be contaminated with radiatio n and they are stopping all exports. This radiation from Japan has the potential to cause worldwide biological disruptionReferencing/SourcesBuz/ed Causes and effects of land pollution Online purchasablehttp//www.buzzle.com/articles/causes-and-effects-of-land-pollution.html (accessed 20th work on 2011)Biodiversity lectures Online Availablewww.uws.ac.uk field Geographic Air pollution Online Availablehttp//environment.nationalgeographic.com/environment/global-warming/pollution-overview.html (accessed 20th march 2011)Goudie, A. and Viles, H.(1997) The Earth Transformed An introduction to human impacts on the environmentImages Radioactive waste Online Availablehttp//homepages.uel.ac.uk/u0852279/Docs/Radioactive.html Picture (accessed 20th march)Air pollution Online Availablehttp//homepages.uel.ac.uk/u0852279/Docs/Air.html (accessed 20th march 2011)Land Pollution Online Availablehttp//homepages.uel.ac.uk/u0852279/Docs/Land.html (accessed 20th march 2011Water Pollution Online Available http//homepages.uel.ac.uk/u0852279/Docs/Water.html (accessed 20th march 2011)Image Online Availablewww.imagesfrom.co.cc (accessed 20th march 2011)Water Pollution Online Availablehttp//library.thinkquest.org/26026/Environmental_Problems/water_pollution_-_effects.html (accessed 20th march 2011)Habitat Destruction Online Availablehttp//www.library.thinkquest.org/08aug/00473/habitatdestruction.html (accessed 20th march 2011)Japan Earth Quake Online Availablehttp//news.slashdot.org/story/11/03/12/038218/Nuclear-Emergency-Declared-At-2-Plants-In-Japan?from=rss (accessed 21th march 2011)Water Pollution Online Availablewww.peakwater.org (accessed 22nd march 2011)University of the West of Scotland (n.d.)
