1、The so-called genius is a lie, and hard work is real.精品模板助您成功！（页眉可删）全球变暖的英文演讲稿作文 全球变暖的英文演讲稿作文1I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future.
2、Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.First of all, global warming is one example, soak in t
3、he hot weather in summer air conditioning becomes a new hobby, but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste
4、 a lot of electricity, so try to avoid using the air conditioning or appropriate use.Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust s
5、erious affect our nong cough, throat inflammation. . According to concerning sectional statistic Chinas per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.More important reason is that: reduce forest, farmland, water damage a
6、nd serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs of the south-north water diversion project.In order to save the planet, people all over the world should be: dont open air conditionin
7、g, use recycled environmental protection bags, dont use plastic bags, take the bus, dont throw waste batteries. Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this
8、is a powerful force!全球变暖的英文演讲稿作文2Environmental ProtectionNo one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.There ar
9、e numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the sol
10、ving of the problem.examdaIt is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effe
11、ct and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .全球变暖的英文演讲稿作文3People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have f
12、requently experienced snowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels.
13、What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds
14、our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.全球变暖的英文演讲稿作文4With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which i
15、s considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike.So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to wor
16、k on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.全球变暖的英文演讲稿作文5After investigation, we found that caused the main reason for the increase
17、of greenhouse gases is human activity. Carbon dioxide, for example, before the human society to realize industrialization in the early 19th century, the concentration of carbon dioxide in the atmosphere to 270 parts per million, and in 1988 to rise to 350 PPM. Atmospheric co2 concentration increased
18、 there are two main reasons: first, the dramatic increase in population and the development of industrialization, human society, consumption of fossil fuels has increased dramatically, combustion produces a large amount of carbon dioxide into the atmosphere, increase the concentration of carbon diox
19、ide in the atmosphere: second forest reduces the amount of carbon dioxide absorbed by plants use, a speed reduction in carbon dioxide is consumed, also leading to higher concentration of carbon dioxide in the atmosphere. Greenhouse gases than carbon dioxide, such as methane, CFCS (freon), nitrogen o
20、xide and so on also need to increase a different level.Although there are many uncertainties, it is clear that global warming on climate, rainfall, and the influence of sea level and the resulting impact on human settlements and the ecosystem is extremely complex, must be given the attention they de
21、serve. Think this kind of influence is irrelevant in the long run view is irresponsible.The main cause of global warming, the atmosphere is destroyed, serious pollution and greenhouse effect caused by global warming could affect global warming will bring to the earth and human complex potential impa
22、ct, both positive and there are also negative. Such as temperature height, deputy polar regions may be more suitable for human habitation, under appropriate conditions, higher co2 concentration can promote the photosynthesis, which plants have a higher rate of carbon sequestration, lead to the increase of plant growth, namely the stimulation effect of carbon dioxide, which is the positive impact of global warming. But compared with the positive impact, the negative impact of global warming on human activity will be more vast and far-reaching.全球变暖的英文演讲稿作文
