课件网) Unit 8 Green Living Reading club 2 To read and understand a longer text on environmental treats. To read for detail and answer questions. To answer a critical thinking question. Learning objectives In many ways, life has become far more comfortable and convenient in the past few decades. However, this has come at a huge cost to the environment. Here, we look at three of the most serious environmental problems we are currently facing. Lead-in Air Pollution Global Warming Overflowing Landfills Discuss the environmental problems and make notes on these three points: Cause – Effect - Solution Air Pollution The main cause of air pollution is the burning of fossil fuels1 by vehicles and power plants. Other human activities，such as construction and the burning of waste，also contribute to air pollution. NOTES 1 fossil fuel 化石燃料 While-reading The effects on our health can be very serious. According to the World Health Organisation， 2.4 million people die annually from causes directly related to air pollution. Young children，the elderly and people with heart and lung problems suffer the most as a result of this environmental problem. NOTES 1 fossil fuel 化石燃料 While-reading You can easily contribute to reducing air pollution by only using a car to make journeys when it′s absolutely necessary. If it isn′t, try using public transport instead. NOTES 1 fossil fuel 化石燃料 While-reading Global Warming Global warming is the increase in the temperature of the Earth′s near-surface air and oceans. It′s caused by the build-up of carbon dioxide2 and other pollutants3 in the atmosphere. These trap the Sun′s heat and warm up the planet. NOTES 1 fossil fuel 化石燃料 2 carbon dioxide 二氧化碳 3 pollutant n.污染物 NOTES 1 fossil fuel 化石燃料 2 carbon dioxide 二氧化碳 3 pollutant n.污染物 Over the past 100 years，average temperatures around the world have risen by between 0.5 ℃ and 1 ℃ . Scientists predict that temperatures will rise by a further 1℃ to 3.5 ℃ during the 21st century. While-reading NOTES 1 fossil fuel 化石燃料 2 carbon dioxide 二氧化碳 3 pollutant n.污染物 Global warming has already caused a wide range of problems. Sea levels are rising due to the melting of polar ice sheets. Countries around the world have faced extreme weather conditions，such as hurricanes，floods and heat waves. While-reading NOTES 1 fossil fuel 化石燃料 2 carbon dioxide 二氧化碳 3 pollutant n.污染物 For example，the south of France and northern Italy experienced extremely heavy rain and 1,000km/h winds in November 2016. Over 200mm of rain fell in just one night. This resulted in the flooding of the River Po near Turin in Italy. While-reading NOTES 1 fossil fuel 化石燃料 2 carbon dioxide 二氧化碳 3 pollutant n.污染物 Overflowing Landfills Landfills are used for waste disposal in many countries around the world . However，due to the amount of waste our lifestyles produce，these landfills are now reachin ... ...
