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. Air Pollution Global Warming Overflowing Landfills Discuss the three environmental problems and make notes on these three points: Cause – Effect - Solution Read the texts and correct your incorrect information or add any new information. Answer the questions. 1. What are the causes and effects of air pollution The causes of air pollution are: the burning of fossil fuels, construction, the burning of waste. The effects of air pollution are: serious health problems and deaths. 1 2. What is global warming and how does it affect our planet Global warming is the increase in the temperature of the Earth’s near-surface air and oceans. It affects our planet in many ways: sea levels are rising due to the melting of polar ice sheets and countries around the world have faced extreme weather conditions, such as hurricanes, floods and heat waves. 3. What are landfills and why are they becoming a serious problem Landfills are big spaces of land used for waste disposal. They are becoming a serious problem because landfills are now reaching capacity and therefore the amount of chemicals in the waste entering our water supply increased. 4. What are the possible solutions to these environmental problems Some possible solutions to these environmental problems are: using public transport instead of driving, recycling your waste and reducing the amount of waste you produce. Cause: the burning of fossil fuels, construction, the burning of waste Effect: health problems and death Solution: using public transport instead of using a car Cause: the build-up of carbon dioxide and other pollutants Effect: sea level rising, extreme weather Solution: energy saving and reduction of carbon emissions Cause: the amount of waste we produce reaching landfills capacity Effect: the increasing risk of dangerous chemicals polluting our water supply Solution: four Rs(Reduce, Reuse, Recycle and Responsibility) Watch the video. Have you learnt anything new Can you think of some more environmental problems What cause these environmental problems What can we do to solve these environmental problems What do you think of the fourth R- Responsibility What does this mean in the context of the lesson Do you think it’s more important than the other three Rs (Reduce, Reuse and Recycle) Why 2 1. According to the World Health Organisation, 2.4 million people die annually from causes directly related to air pollution. annually adv. once every year 每年；一年一度地 e.g. The jazz festival is h ... ...
