Free talking: What will you do for protecting the environment？Step 2Reading Task1.Introductory remarks (10mins)1) Background information:Since at least the 1970s people have been aware of environmental issues, but in recent years widespread concern has focused more on climate change and global warming. Climate change is one result ofglobal warming, and has serious potential consequences. It could cause ice caps to melt, which would lead to a rise in sea levels, which in turncould endanger coastal cities. Climate change could also cause increases in droughts, floods, storms and cyclones, which could affect water supplies and lead toan increase in deserts and a decrease in harvests, and thus food shortages. So environmental awareness is important for everyone.2)Environmental awarenessIt means that people are aware of their impact on the environment. This includes an awareness of major environmental issues, such as climate change, global warming, pollution, recycling and energy-saving, and the role of people in them. Environmentally-aware people have some knowledge of possible solutions and make commitment to practical action towards solutions. This commitment is often called “green”. If businesses use a green label, they try to show that they support the protection of the environment. The meaning of environmental awareness has become broader as people have come to understand the complexity of environmental problems and the impact of people on the environment3) carbon footprintThecarbon footprint is a measure of the direct contribution of carbon from energy use. The element carbon is added to the earth’s atmosphere by the use of energy in lighting,heating or cooling houses, cooking, driving cars, flying planes and other human activities. This has an impact on the environment and affects climate change because it adds to greenhouse gases which contribute to global warming. Indirect carbon emissions from manufacturing and transport also create a carbon footprint. By measuring the carbon footprint we can get an idea of what each of us contributes to the climate change and what effect our actions may have on lowering the footprint, or reducing carbon emissions.Step 3 Comprehending the text(15mins)1.
