Pollution REVISION 8F1

Write your name and class section Impact Matching Match the negative human impacts previously discussed to the correct definition. Invasive Species capable of causing extinctions of native plants and animals, reducing biodiversity. Global Warming caused by increased concentrations of carbon dioxide in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming. Deforestation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere. Acid Rain caused by the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, Ozone Depletion occurs when chlorofluorocarbons and halons—gases formerly found in aerosol spray cans and refrigerants are released. Air Pollution Air pollution comes from a lot of different sources. Fossil fuels like coal, gas, and oil release particles of soot and dust when they're burned. Power plants, factories, and even the furnaces and stoves we use to heat homes and offices add to the air pollution. Cars burn gasoline, and that also adds a lot of dangerous chemicals to the air. Smog is a mixture of fog or haze combined with smoke and other air pollutants . What can you INFER from the fact that smog mainly affects cities? People foolishly built cities in areas with heavy smog. Air pollution never affects rural areas. People in cities drive more often than people in rural areas. Air pollution is most serious in areas with many homes, factories, and offices. Which of these is an OPINION about air pollution? It's the biggest threat that humans face. It can be caused by burning fossil fuels. Not all air pollution comes from man-made sources. Humans can take steps to decrease the pollution they release. According to the graph above, which source contributes the greatest amount of air pollution? running factories building homes driving cars cooking food Water Pollution Pollution can enter a body of water in a few ways: as acid rain; as eroded soil; as runoff containing fertilizers and pesticides; as chemicals released from industries; or as sewage and other wastes from cities and towns.Quite a bit of water pollution is created by each of us as we go about our business from day to day. Simple activities like flushing waste down our toilets, washing our cars and using laundry detergent in our washing machines release pollutants into the groundwater. Which pollutant is most commonly released into waterways by families and individuals? Laundry detergent Pesticides Fertilizer Acid rain According to the graph above, what percentage of ocean pollution comes from litter? 5% 10% 20% 30% What can you infer is the most reasonable way to help prevent water pollution? By being careful with household chemicals you dump down the sink. By refusing to use products made in large factories. By never taking a bath or shower for more than 10 minutes. By drinking as little water as possible. Classify each of the following as a human activity or negative effect on the environment. Human Activities Agriculture Over consumption Combustion of Fossil Fuels Overpopulation Disposal of waste Transportation Negative Effects Air Pollution Deforestation Loss of Diversity Acid Rain Global Warming Rise of Sea Levels In your point of view, is the damage to the environment reversible? Explain your answer and SUGGEST solutions we can do daily to decrease negative human impact on the environment.
