50分 急求一份关于 气候变化 的英语演讲稿，谢谢
Thank you very much. Good morning. I want to thank the Secretary General for organizing this summit, and all the leaders who are participating. That so many of us are here today is a recognition that the threat from climate change is serious, it is urgent, and it is growing. Our generation's response to this challenge will be judged by history, for if we fail to meet it -- boldly, swiftly, and together -- we risk consigning future generations to an irreversible catastrophe. No nation, however large or small, wealthy or poor, can escape the impact of climate change. Rising sea levels threaten every coastline. More powerful storms and floods threaten every continent. More frequent droughts and crop failures breed hunger and conflict in places where hunger and conflict already thrive. On shrinking islands, families are already being forced to flee their homes as climate refugees. The security and stability of each nation and all peoples -- our prosperity, our health, and our safety -- are in jeopardy. And the time we have to reverse this tide is running out. And yet, we can reverse it. John F. Kennedy once observed that Our problems are man-made, therefore they may be solved by man. It is true that for too many years, mankind has been slow to respond or even recognize the magnitude of the climate threat. It is true of my own country, as well. We recognize that. But this is a new day. It is a new era. And I am proud to say that the United States has done more to promote clean energy and reduce carbon pollution in the last eight months than at any other time in our history. We are making our government's largest ever investment in renewable energy -- an investment aimed at doubling the generating capacity from wind and other renewable resources in three years. Across America, entrepreneurs are constructing wind turbines and solar panels and batteries for hybrid cars with the help of loan guarantees and tax credits -- projects that are creating new jobs and new industries. We're investing billions to cut energy waste in our homes, our buildings, and appliances -- helping American families save money on energy bills in the process. We've proposed the very first national policy aimed at both increasing fuel economy and reducing greenhouse gas pollution for all new cars and trucks -- a standard that will also save consumers money and our nation oil. We're moving forward with our nation's first offshore wind energy projects. We're investing billions to capture carbon pollution so that we can clean up our coal plants. And just this week, we announced that for the first time ever, we'll begin tracking how much greenhouse gas pollution is being emitted throughout the country. Later this week, I will work with my colleagues at the G20 to phase out fossil fuel subsidies so that we can better address our climate challenge. And already, we know that the recent drop in overall U.S. emissions is due in part to steps that promote greater efficiency and greater use of renewable energy.

Global WarmingThere 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.

关于环境的英语演讲稿
保护环境英语演讲稿We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one.Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big problem.

topic of global warming is attracting attentions of countries all over world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make large sections of the earth uninhabitable. What have caused global warming? The theory and evidence strongly suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so. A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A further recommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions. China is the rising economic star; and if it also wants to assert world leadership status, it is a good opportunity for China to show the world that it has a moral commitment and the will to fight global warming.
五分钟演讲稿关于日本的文化,历史,要求材料证明
你好，希望对你有帮助。
Humans and nature are quite connected. Nature is extremely significant for humans. Nevertheless, Humans exert tons of pressure on the natural world. Habitats and species suffer not only from environmental changes caused by industry and technology but also from the strain caused by the massive human population in the world. There are many upcoming global challenges for humans, such as greenhouse gases driving climate change and shortage of fuel. In the long run, people could take effective action to relieve frustration in their power. Taking a bicycle as a way out is getting more dominant gradually. It reduces dramatically the exhaustion from the vehicle. Furthermore, scientists are trying to open up more new sources of energy instead of traditional sources of energy with the passage of time.To sum up, everyone has an obligation to exert their power for a better nature.
