Humans Effect on the Environment
The Effect of Humans on The EnvironmentThe Greenhouse Effect/Global WarmingThe greenhouse effect is the rise in temperature that Earth experiences.Global warming is an increase in the earth's temperature due to the use of fossil fuels and other industrial processes leading to a build-up of ¥green house gases'. Water vapor, nitrous oxide, carbon dioxide and methane trap energy from the sun. These gases contribute to the greenhouse effect. The carbon dioxide comes mainly from burning fossil fuels in power stations. The nitrous oxide is released from a fertiliser used in agriculture. The extra methane is produced in coal mining, natural gas production and distribution. All fossil fuels when burned produce carbon dioxide.The graph shows how much each gas contributes to the greenhouse effect, taking into account how much of it there is and how much and how radiation it can absorb.If it weren't for these gases the heat would escape from the Earth into space. These gases warm our world, without them Earth would be about 60 F cooler, therefore Earth would not be warm enough to live in. However, if the greenhouse eff
Eutrophication: When nitrates and phosphates from farmland and sewage escape into the water. Before extracting the sand and gravel an Environmental Impact assessment must be carried out. Eutrophication: The rivers and lakes are full of water plants that compete for light. A young wheat crop is sprayed with herbicide to suppress weeds. Also as pesticides are passed along the food chain, the concentration of the pesticide increases, therefore, killing animals or humans sometimes. Farmers use fertilizers to improve their crop yields. This looks at all likely affects of the extraction and includes noise, dust, pollution and visual. What causes it?Sewage: Is caused by the faeces passed by people, who suffer from diseases such as typhoid and cholera, it contains harmful bacteria. This has been accompanied by an increase in the standard of living. Heavy rainfall washes the rainfall off the hillsides into the rivers. Combustion in the engines of cars produces a gas called Carbon Monoxide. The conservation of the environment is extremely important, because if the environment continues to be destroyed in years to come earth will not be a place for humans to live in and humans may become extinct. These are derived from coal and petroleum. Lakes and rivers become choked with silt and this leads to floods.
