随着人口的增长,气象变动和环境的好转如何浪费食物和水,英语作文
1. Human beings are dependent on the Earth’s diversity of species. Wild species play a vital role in the maintenance of the planet’s ecological functions, yet every day on the planet 40-100 species become extinct. 2. Human life cannot exist in the absence of complicated interactions of millions of species in biological systems.3. 50,000 plant an animal species disappear each year due to tropical deforestation, expanding agriculture and human settlement.4. Human activities impact the environment, including clearing agriculture land; air, land and water pollution; urban and suburban development; and the introduction of invasion or non-native wildlife species. If land and wildlife are poorly managed, human being will risk fragmenting habitat.5. We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientist. More than two billion pounds of chemicals are spewed into the air each year. These chemicals are brewing a disastrous stew, resulting in an atmosphere crisis. The greatest consequences of the atmosphere crisis may be global warming and the ozone depletion. If human kind wants to survive well into the next millennium, we must stop this horrible destruction of our own environment.6. The earth appears to be warming due to the greenhouse effect. Scientists estimate that the average temperature could climb about 2 degrees Celsius in 20 years. This change in the global climate would have disastrous results, including drought, coastal flooding and increased species extinction. And, scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the Sun. Once the ozone layer is completely destroyed, all life on Earth will cease to exist, killed by the deadly radiation. The planet will become a barren rock devoid of all life.7. It allows for an unbelievably large amount of downloads and uploads of information, music,videos and all sorts of other things, as it is the engine of the information superhighway of our Information Era, in witch we live.
以管理气象变暖为题的英语作文
Control warming is everybodys businessFashionable girl pursue office, the weight is about tax, is student, now, you enquiring carbon reduction? Also become a vulgar. The typhoon, frequent droughts, floods, accelerating melting glaciers, species extinction, these are the tragedy of global warming, coal, oil and fossil energy consumption of the carbon dioxide that cause global warming is the day we must breathe, Internet, electricity, car... All of these can cause emissions of carbon dioxide. So, from morning till evening sleep a day, we how much carbon emissions? According to statistics, China familys annual average of carbon emissions is 2.7 metric tons. The reporter understands, many citizens living in nanjing details to pay more attention to reduce energy consumption, the method is more scientific and trendy, low carbon life has become a new attitude to everyday low carbon calculateWe live in each bit by bit can be quantified for digital, the reporter understands, network has begun to pop low carbon calculator: life, carbon calculator whole calculator, energy conservation and emission reduction in carbon emissions computing website... Some of the net, net watercress is built on low carbon various life, actively promote the team carbon neutral concept, study how to reduce carbon emissions, teach how users low carbon enjoy 80 benign in college is a real environment, is the low carbon. She tells a reporter, the side of the everyday a friend for weight loss, but she stands on the network, every day will use the carbon calculator to own low carbon. Go down stairs a floor to reduce carbon emissions, 0.218 kilograms less air conditioning for an hour 0.621 reduce carbon emissions, with less kilogram ton water reducing 0.194 kilograms carbon emissions, less with 10 pairs of disposable chopsticks, can reduce 0.2 kilograms carbon dioxide xin often to family and friends extension of low carbon concept and reduce energy consumption of the coup. Even eat less meat is a product of environmental protection, because the animal husbandry will spend more than vegetable production of energy, eat less 0.5 kilograms carbon dioxide emissions, but meat 700 grams. Li xin tells a reporter, many friends, now that his childhood, make a habit of changing low to carbon dioxide did youThese data is how to calculate? The world wide fund for nature (WWF) global climate change response plan and director of dr Yang told reporters, examine to carbon dioxide is easy, whether individual eat and drink pull scatter sleep, or all three of daily life, emissions of carbon dioxide can be understood how to calculate. For example, household electrical carbon dioxide emissions (Kg) = power degree 0.785 x, Drive co2 emissions (Kg) = consumption liters x number of 2.7, Fly to the excursion within 200 kilometers (Kg) of carbon dioxide emissions 0.275 x = Yang to reporters on bill. Each day through breathing about release carbon dioxide 1.14 kilograms, The computer USES a year on average 1.5 kilograms carbon dioxide indirect, A car engine fuel burning liter per releasing carbon dioxide to the atmosphere 2.5 kilograms. In China, a city white-collar even only 40 square meters of residential area, the car emissions from 1.6 L, one plane 12 times, carbon emissions in 2611 is terrible, low carbon life really is we need build green lifestyle. The home for the energy-saving bulb, air temperature down two degrees Celsius, reduce time watching TV with water, wash basin, insist to wash clothes. Dr Yang said all these things, and his side can be low carbon can really change the earths temperature?Many people would have such doubt, if we are in the note drops of low carbon, really can alleviate the earth warming steps? Dr Yang certainly told reporters, low carbon life, to slow global warming effect is very told reporters, carbon dioxide can exist on earth, earth in hundreds of carbon dioxide or the human production since the industrial revolution. In 100 years, global emissions of carbon dioxide will be increased to the original twice, heating has become inevitable. Until now the human still continuously produce large amounts of carbon response to climate change, people put more attention focused on reducing agricultural production in the field of carbon dioxide emissions, but often ignored the urban residents of the daily life of carbon dioxide emissions. Dr Yang said in the daily life, everyone has his own carbon footprint, it is everyones greenhouse gas emissions. According to the calculation, 1999 and 2002, urban residents living in every country can take some 26% of energy consumption, carbon dioxide emissions by 30% of the residents living is to satisfy the demand of behavior and cause. Urban residents have become the largest carbon dioxide customer. 管理变暖人人有责时兴女孩谋求的是“减肥”，任务族在意的是“减税”，在校生关注的是“减负”，如今，你“减碳”了吗？也成为一句盛行语。
频繁的台风、干旱、洪水，冰川减速消融，物种减速灭绝，这些都是环球变暖带来的劫难，而煤炭、石油等化石动力消耗发生的二氧化碳正是造成环球变暖的罪魁祸首。
咱们每天都要呼吸、上网、用电、坐车……这些都能形成二氧化碳的排放。
那么，从早上起床到早晨睡觉，咱们一天究竟排放了多少碳呢？依据统计，中国度庭每年碳排放量的平均水平为2.7吨。
记者了解到，南京许多市民在生存细节上更留意节能减耗，模式方法也更迷信新潮，“低碳生存”也成为一种新兴的生存态度。
“低碳达人”天天“共计”自己 “原来咱们生存中每一点一滴都是可以量化为数字的”,记者了解到，网络上曾经开局盛行各种低碳生存计算器：“碳排放计算器”、“全民节能减排计算器”、“碳排放量计算网站”……豆瓣网的一些网友,更是建起了各式各样无关“低碳生存”的小组,他们踊跃推行“碳中和”概念,钻研如何缩小碳量排放,教网友如何“低碳”地享用生存。
“80后”的李欣在大学里学的是环境专业，是一个地纯粹道的“低碳族”。
她通知记者，身边的不少闺蜜们每天都在为减肥忧虑，而她却特立独行，每天会用网络上的“碳排放计算器”来计算自己的“低碳生存”。
“走楼梯高低一层楼能缩小0．218千克碳排放，少开空调一小时缩小0．621千克碳排放，少用一吨水缩小0．194千克碳排放，少用10双一次性性筷子，可缩小0.2千克二氧化碳的排放……” 李欣时常向家人和好友推行低碳理念和缩小动力消耗的妙招。
“连少吃一顿肉也是环保，由于畜牧产品的消费比蔬菜会消耗更多的动力，少吃0.5千克的肉，可减排二氧化碳700克。
”李欣通知记者，身边有很多好友，如今都开局保持从小习气扭转自己，做个“低碳族”。
专家教你给二氧化碳算账 这些数据又是如何计算进去的呢？ WWF（环球人造基金会）环球气象变动应答方案主任杨贫弱博士通知记者，给二氧化碳算笔账其实很容易，不论是团体的吃喝拉撒睡，还是一家三口的日常生存，排放了多少二氧化碳都能一清二楚地计算出。
比如，家居用电的二氧化碳排放量（Kg）= 耗电度数×0.785；开车的二氧化碳排放量（Kg）=油耗公升数×2.7；乘坐飞机启动200公里以内的长途游览的二氧化碳排放量（Kg）=公里数×0.275…… 杨博士给记者算了笔账。
每人每天经过呼吸大概监禁二氧化碳1.14千克；电脑经常使用一年平均直接排放二氧化碳10.5千克；汽车的一台发起机每熄灭1升燃料向大气层监禁二氧化碳2.5千克。
在中国，一个市区白领即使只要40平方米的寓居面积，开1.6L排量的车上任务，一年乘飞机12次，碳排放量也会在2611吨。
“这个数字其实挺可怕的，低碳生存真的是咱们急需建设的绿色生存模式。
”“把家中灯泡换为节能灯，把空调温度调低两摄氏度，缩小看电视期间，用洗脸盆接水洗脸，保持用手洗衣物。
”杨博士示意这些都是自己身边的大事，棘手能做到。
“低碳生存”真能扭转地球温度吗？ 不少市民会有这样的纳闷，咱们假设点点滴滴都在留意“低碳”，真的能缓解地球变暖的脚步吗？杨博士必需地通知记者，全民低碳生存，对减缓地球变暖的成果是十分渺小的。
他通知记者，二氧化碳在地球上能够存在上百年，如今地球上的二氧化碳还是工业反派以来人类制作的。
在100年内，环球二氧化碳的排放量将参与到原有的两倍左右，升温已成为肯定。
到如今人类还在源源始终地发生少量的二氧化碳。
在应答气象变动疑问上，人们把更多的眼光聚焦于缩小工农业消费畛域的二氧化碳排放，却往往漠视了市区居民日常生存所发生的二氧化碳排放。
杨博士说，在日常生存中，每团体都有自己的碳足迹，它指的是每团体的温室气体排放量。
据测算，1999年到2002年间，城镇居民生存用能已占到每年全国动力消费量的大概26％，二氧化碳排放的30％是由居民生存行为及满足这些行为的需求形成的。
市区居民也成了排放二氧化碳的“最大客户”。
