防全球变暖演讲稿篇1
people 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 frequently 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. 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 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.
防全球变暖演讲稿篇2
in recent years do you think the weather suddenly turned hot had the cool autumn now almost until early october the hottest day in august has reached more than 40 degrees. these is different from normal vision we have ourselves to blame the curse.
today the term "global warming" has gradually penetrated into our life. the word sounds very academic even feel very far away from us so some people are not. in fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels and so on. both harm the natural ecosystem balance more threatening human food supply and living environment.
now that you have aware of the dangers of global warming you should go to predict and improve it. imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms the next round of searing heat the next major natural disasters will happen? china? the united states? japan? no one knows. the debate has ended. scientists around the world agree points out that the earth's average temperature has increased nearly 1 ℃. due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. scientists will have the most advanced computer data input model to estimate the earth can face the future. prediction results are worrying. forty years later the himalayan glaciers the water to the survival of millions of people are likely to disappear. the greenland ice sheet could melt in 50 years. currently half of the world's biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land by the end of the century. is likely to be the future of the world like in the movie "the day after tomorrow" tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... this is not a crazy fantasy if humans don't stop destroying the environment it will become a reality!
however in the warming is also good. global warming on rice in heilongjiang province has played a large role.
just global warming to human future development is still the do more harm than good.
in order to save the planet we should try to be: don't open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide don't use plastic bags r22 by bus; r22; little drops of life. actually it's not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.
thank you all!

尊敬的老师，亲爱的同学：
大家好!
到了十五六岁的年纪，我们也都清楚了环境的重要性。就像现在我们正坐在这个偌大的操场一样，如若当我们离开时，操场还会像之前一样干净的话，那么也就证明着我们每个人的卫生习惯提升了不少，所以不管是对于整个大环境还是个人的卫生习惯，我认为我们都是应该要花费一些心思的。在此，我呼吁大家和我一起执起青春的旗帜，一同维护我们的卫生，一起保护我们的社会环境。
前几天看到一则非常感动的新闻，一所学校高考完之后，外面的家长等候区0垃圾，当清洁员抵达现场的时候也震惊了，往常每次人群聚集之后就会留下一地垃圾，这次这么多家长等待子女都没有留下一点垃圾，直接感叹这一届学生家长的素质实在是太高了。看完这则新闻之后，我真的很受感动，现在时代发展的很快，其实我们人也在不断的发展中，我们的个人素质也在不断的提升，所以我们每个人也更应该去做好自己本职的那一份工作了。对于我们高中生而言，就应该在做好学习工作的同时，注重对周围环境的维护和保护。那么主要表现在哪几个方面呢?
首先就是要维护好自己身边的环境，也就是我们的校园环境，从身边做起总不会是一件错误的事情。其次就是要把视野放到更远的地方，保护森林，保护野生动物，为更多的生物创造出一个更加舒适的环境，也为我们人类自身的生存环境创造一些更好的条件出来。因此这两点是我们都可以做到的事情，而此刻，也让我们在内心更加坚定一些。肩负起这份责任，为我们这个社会，为我们自己的生存环境贡献一些力量。
在保护环境方面，我们每个人都可以是一位英雄，我们向城市的每一位环境工作者致敬，也向每一个对社会环境有巨大贡献的人致敬。在二十一世纪的今天，我们也应该把更多的目光交给环境了，我们要从长远去考虑，坚持可持续发展的原则，不管是在平时的生活，还是自己思想的提升方面，我们都应该好好去考虑这样的一件事情了。让我们拿出自己的一点力气来，去坚持做这份环保工作吧!让我们成为新时代的翩翩少年，让我们成为环保路上的引航者!

i 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. 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 the 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 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 serious affect our nong cough, throat inflammation... . according to concerning sectional statistic china's 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 and 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: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't 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 is a powerful force!
防全球变暖演讲稿篇5
global warming
there is little doubt that the planet is warming. over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). the warmest since the mid 1800’s was the 1990s. the hottest years recorded were 1997, 1998, 2001, 2002, 2003.
the united nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. if the ice caps melt, a vast majority of our countries borders will be under water. monuments and great buildings, as well as homes and lives will be under water, including new york city.
so now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?
the answer is simpler than you may think. you don’t have to go miles away from home to protest, or spend masses of money. if you try to follow the few simple steps that i shall now give you, you will have started to help us all.
firstly, plant a tree. this could be easier than it sounds. join or help out a local wildlife group and ask to plant a tree. trees, when fully grown, will help keep the planet cooler. on the same point, you could protest against the demolition of the rainforests. this is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.
something as simple as walking instead of taking the car will help reduce pollution. as well as stopping pollution, you are giving yourself exercise, something important for our bodies. so the next time you get into your car, or your motorbike, think - do i have to make this journey by vehicle or can i walk?
when you are at home, and your getting a little cold. put a jumper on and do not adjust the heating. the extra heat produced by our homes also affects the planet. so try wearing an extra layer in winter.
if possible, buy your fruit and vegetables from local suppliers. and try to avoid imported goods. the more foreign food that we import the more pollution from aeroplanes and boats it will create.
keeping to the speed limit can also help the environment. the more you speed the more petrol you are going to use, making the pollution higher. also, suv’s make about six times their own weight in co2 each year. a small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.
if possible use solar energy, after all it is free; all you need to buy is the equipment. you can get much of your hot water and heating from the sun and even generate electricity.
reduce, reuse and recycle. only buy what you need; don’t stock the cupboards with things you may or may not use. reuse whatever you can, like containers and paper, and recycle what you cannot reuse. it really is as simple as that.
finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.
if everybody stuck to these rules, we would be doing a great thing by protecting the earth. so please take into consideration what i have said, and try to do your part. after all, it will be our next generation that will feel the effects.
