low carbon living Part 1I give you an account of two subjectsAir conditioning to exclude the methane-containing gases cause global warmingThe second one is about the increasing amount of cars Air conditioning is bound to bring some burden on our environmentAnd we use any kind of industrial products,air conditioning is bound to bring a certain burden to our environment.Energy to open the timber and release large amounts of heat to the atmospheric environment,has been a great burden to our natural environment into a ring,this is a long time to solve the major problemsWhat are the hazards of vehicle exhaust on the environment?The car is a modern means of transport,with the surge in the number of cars,worsening environmental pollution caused by automobile exhaust.The harmful components in the vehicle exhaust of CO,NOx,SO2,HC,and particulate matter and ozonein 21st century,there are 7 millions cars in the world,a large amount of exhaust gases has seriously influenced us,such as:cough,throat inflammation.We should have a healthy way to travelThe global climate is becoming warmer and warmerNearly 100 years,the average global temperature has experienced two fluctuations,which is the well-being of well-being.In general,it is a general trend,the global climate is becoming warmer and warmerMany parts of the land becomes very dryFor example,last spring,the most severe drought in 50 years hit northern China affecting the livelihood of 4 million people.They are looking forward to the rainEnvironmental damage and climate change is a reality for us.Out of the worlds most polluted 20 cities,half are in China,70%of Chinese rivers are polluted.China has become the largest carbon emitter of the world Part 2What is a low-carbon living?Low-carbon life is two words,life refers to the clothing,food,housing,transportation lines,such as aspects of personal lifestyle according to personal habits.Why should we be low-carbon life?Order to reduce carbon emissions and dependence in life Carbon dioxide is essential for plants to absorb carbon dioxide for photosynthesis,and carbon dioxide remains within the appropriate range is very important for maintaining the Earths temperature suitable for human habitationClimate change and our relationshipPolar ice meltingThe polar bear to lose a footholdAll kinds of extreme weather,droughts,floods,storms,ice storm,fire,use the adjective rare historical,once in a century to describe the situation is grimPeople lost their homes because of fireSnow-ice roads and carOur Earth is a variety of attacks of extreme weatherThis would cause great harmWe should make every effort to protect the EarthPart 3How do we achieve a low carbon lifeMy understanding is that the low-carbon in their daily lives from ourselves,from the trivial,to minimize all possible consumption Water conservation is the energyWater is our source of lifeMany people are no water to drinkTheir desire for water is far beyond our imaginationIn addition,if monthly wash clothes,so once per washer can save electricity,also saves power of the coal,also will reduce carbon emissions,if all the family can do monthly by hand to wash clothes,reduce the emissions of carbon dioxide once is 68.4 tons,can achieve this figure is very surprising.So for us students have more ways energy-savingDo not let the desert from the birth of your handsNeed not disposable chopsticks and disposable lunch box The use of disposable plastic will cause great pollutionBags instead of plastic bags is a wise choiceReduce food waste Our earth needs we work together to love,let us start from around things,cherish resources,reduce the energy consumption and make our life more beautifuThank you!
