Tài liệu là bài viết ngắn gọn về các vấn đề của global warming bao gồm: effect, causes, solotion. Bài ngắn ngọn nhưng đủ ý, chính xác, vào thảng vấn đề ( vì là tài liệu tự soạn nên sẽ không bị trùng với các tài liệu khác)
Global warming * Effects: Weather-related natural disasters such as drought and flood, that can kill or injure large number of people Earth's temperature tise -> reduce crop harvestes globally, which may lead to famine Water source is affected -> water shortages are likely to deley encomic growth and damage ecosystems Milion of species in the world disappeared Rise of sea levels -> milions of people lose home and floods increase Infectious diseases increase Because disease-causing insects are easy to multiply in hot and humid weather Air pollution -> affects human health *Causes: Burning fossil fuels When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere Deforestation & Tree-Clearing Plants and trees play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it Agriculture & Farming Animals, livestock like sheep and cattle, produce methane, a greenhouse gas When livestock grazed at a large scale, as in Australia, the amount of methane produced is a big contributor to global warming *Solution: Reduce waste and recycle it-> The burning of many types of waste increases the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the greenhouse effect and global warming So we should choose products that can be reused instead of thrown away Planting trees to reduce global warming-> Trees absorb carbon dioxide, so planting more trees can help reduce the amount of carbon in our atmosphere Replace traditional light bulbs with LED lights-> Recycling light bulbs is extremely difficult and expensive We can use LED lamps instead, they provide more natural looking light while using much less energy than other types of bulbs Buy what you really need and will use ->Reduce, re-use, and recycle—it’s not just about pollution, but the strategy will lower your emissions and help combat global warming reduce energy use everywhere -> It doesn't matter whether you are at home or in your office, the higher the energy use, the more carbon dioxide it produces Thus, no electricity is wasted as it requires burning fossil fuels As a result of burning fossil fuels, greenhouse gases in the atmosphere rapidly increase and contribute to global warming
