Poor agricultural practices, digging up of important resources and dumping of garbage underground can cause land pollution. Urbanization, the growth of rural lands into urban areas and industrialization that results in the formation of an industrial society are regarded as the two main causes of land pollution. The excavation of minerals, the increasing quarrying and mining activities lead to land pollution. The excavation and mining activities lead to the loosening of soil. Increased mechanization leads to the contamination of soil, thus causing severe land pollution. 2 Land Pollution Deforestation is one of the major causes of loosening of soil that in turn causes soil erosion. The soil that is left naked on harvesting crops from agricultural lands is vulnerable to being eroded by wind and water. Intensive agricultural practices cause the soil cover to lose its nutritional elements, making it of no use for agriculture. Excessive use of pesticides and chemical fertilizers causes soil contamination. Chemicals can prove harmful to the animal and plant life. An excessive use of chemicals leads to a decrease in the fertility of soil. Certain herbicides and insecticides lead to toxicity of soil. Fungicides contain copper and mercury, which are extremely harmful to the soil as well as the plant and animal life that thrives in it. Inefficient and unhealthy methods of soil management and harmful irrigation practices lead to soil pollution. 3 Land pollution Agricultural and industrial waste, solids from sewage treatment plants, ashes and garbage are other causes of land pollution. The accumulation of inorganic wastes in soil poses a threat to the plant and animal life in that area. Garbage is carelessly dumped into the soil. Non-biodegradable wastes such as plastic and rubber prove lethal to the life in the soil. Plastic and glass bottles, cans, rubber tires and electronic items dumped in the soil make up the main cause of land pollution. Solid wastes are harmful to the terrestrial plants and animals. The growth of food is a huge contributor to land pollution. Chemicals such as herbicides and pesticides are used to help the crops to thrive. These chemicals can erode soil and make areas of land hard to use for further crops to grow if the farmers aren’t very careful about their efforts. Approximately 20 billion tons of topsoil are lost annually due to land pollution. 4. Land Pollution Effects How does land pollution affect the environment? One of the major consequences of land pollution is the imbalance in nature, resulting from the harm caused to the wildlife and vegetation on the land. It adversely affects the human respiratory system and results in various skin problems if the toxic materials of the soil come in contact with the skin. The consumption of fruits and vegetables that are grown in contaminated soil can lead to several health hazards in human beings. When contaminated soil is washed away in the water reservoirs, it leads to water pollution, which is lethal to the aquatic flora and fauna. In 2009 there were over 20,000 beaches around the world closed to due to land pollution. 5 Land Pollution Effects The soil contaminants are driven by the wind, causing air pollution, which is detrimental to health. It is high time we realize the importance of soil and devise ways to curb land pollution. Maximum use of biodegradable materials and implementation of recycling in order to reuse resources are some of the excellent methods of preventing land pollution It is important to implement proper methods of disposal of organic waste. It is necessary to educate the masses about the causes and effects of land pollution. It is important to understand that land pollution also increases water pollution. This is because what is on the land get washed to lakes, rivers, streams, and ponds when it rains. While the focus is often on cleaning up the bodies of water should also be on the land which is the contributing source of it. XI Listening Teacher: How do you think if land pollution can increase water pollution? Slide №18 A part from BBC Learning English 6 Minute English Plastic Pollution http://tonail.com/6-minute-english-plastic-pollution/ Kate: Hello, Dan! Dan: Now today Kate and I are talking about pollution. Kate: Yes, well pollution is the term for harmful waste which has been put into the environment, and which can be damaging to plants and animals. Dan: So I’m going to start the show today with a question, Kate. Have you ever heard of the ‘Great Pacific Garbage Patch’? Kate: No, I’m afraid I haven’t; I’ve never heard of that. Dan: Well let me explain: Garbage is an American word for something we’ve thrown away, what we in the UK might call rubbish. And the Pacific Garbage Patch is an area of the Pacific Ocean where rubbish has collected. It was discovered in 1997, and is essentially a big floating soup of plastic garbage and bits of rubbish that have been thrown away on land and have ended up in the sea. Kate: Ooh that sounds absolutely horrible. I had no idea that anything like that existed. Dan: Well this is the bit which is really scary: we don’t actually know the size of garbage patch, but some people say it could be 600,000 square miles across which is twice the size of France. Kate: What? Twice the size of France? That’s absolutely huge! Dan: And it could be bigger. Kate: That’s very frightening. Teacher: It is important to understand that land pollution also increase water pollution, when contaminates soil is washed away in the water reservoirs. True or false Slide №19 1. Environment is the term for harmful waste which has been put into the pollution. 2. Kate has already heard of the ‘Great Pacific Garbage Patch’ 3. Rubbish is an American word for something we’ve thrown away what we in the UK might call garbage. 4. The Pacific Garbage Patch was discovered in 1995. 5. The Pacific Garbage Patch is essentially a big floating soup of plastic garbage and bits of rubbish that have been thrown away on land and have ended up in the sea. 6. We actually know the size of garbage patch. 7. Kate says that’s very frightening. XII Then teacher again reads the words of J. Galsworthy: If you don’t think about the future, you will not have it. Do you change you opinion? Slide №20-22 Teacher asks students to write a cinquain. XIII Hometask 1. What are the environmental problems in Petropavlovsk? Write what will happen if we don’t solve these problems. What should we do to solve them? Prepare presentations. 2. Make up and act the dialogue about environmental problems in Petropavlovsk. What will happen if we don’t solve these problems? What should we do to solve them? XIV Marks XV Song “Mother Earth” http://www.youtube.com/watch?v=l_A3FMf3_Qw | |
