What is Environmental Degradation? The deterioration of the environment through depletion of resources, such as air, water and soil. The destruction of ecosystems and the extinction of wildlife. When natural habitats are destroyed or natural resources are depleted, the environment is degraded. There are two factors that lead to environmental degradation: Natural factors includes droughts, storms on sea, land and deserts such as hurricanes, tornadoes, catrina and volcanic eruptions. These factors lead to land degradation caused by erosion. Human factors includes deforestation, industrialization and urbanization. These factors lead to water, air and land pollution. What are the positive and negative consequences of Environmental Degradation? Positive Urbanization– The physical growth of rural or natural land into urban areas as a result of population in-migration to an existing urban area. Cities are places where money, services and wealth are centralized. Social mobility and Diversity increases. Greater Economic opportunities are created. Negative 1. Increases the cost of living, farmers become more mechanized putting labors out of work, reduces soil moisture, more resources are required to meet basic needs and air, water and soil pollution increases. Positive 2. Industrialization-The setting up of industries in a specific area. Where it will be close to a source of raw material. Creates new ideas, products and jobs. Creates mass markets of investments commerce and revenue Soil and Land degradation. When fertile land is lost due to the increase of human population. Construction of homes and highways for travel, farming of crops, negative noise and air water pollution occurs. Increase in health problems creates dangerous machinery, overpopulation of urban areas that leads to shortage of resources. Creates land that is unsuitable for crops, pasture for animals and forests because the soil is too infertile or shallow to plan. Soil composition is greatly affected. Lost of such minerals like nitrogen and phosphorus that are critical for plant growth and increases food shortage Water is the resource that defines all organisms life. We can not live without it keeps the body hydrated. It is essential for life and helps maintain food supply deforestation-The clearing of forest land (tropical forest). Land cleared for paper, fuel and building materials to be used by humans. Land cleared and cut for logging and pulpwood. Land cleared for urban expansions Negative Food supply is threatened by polluted water. Humans waste water by watering lawns and washing vehicles. Water polluted by chemical waste, pesticides, fertilizers and soil sediments that are being deposited into bodies of water. After the tropical rain forests are cleared, little can grow on the land. Death and diseases can result from localized flooding caused by deforestation. Over-harvesting of fuelwood allows invasive species to enter into the forest. Air pollution and acid rain occurs. The rapid increase in the human population provides laborers for jobs such as farming, manufactures and industries. Energy Usage provides electricity for human usage and negative rapid increase in disease and human deaths. The prosperity of life will decline puts enormous stress on the environment while it also limits the availability of natural resources for individuals survival. Pollution generated by burning coal and oil that contributes to the release of carbon dioxide into the atmosphere which has increased Global Warming. “In the United States and Worldwide, we have serious environmental resource problems of water, land and energy, and these are now coming to bear on food production, malnutrition and the incidence of diseases.” Increases in diseases associated with diminishing quality of water, air and soil resources provide evidence of a declining standard of living. About 40 % of deaths worldwide are caused by water, air and land pollution. Such environmental...
