Unit 9 Environment
Unit 9 Survival Environment 原文答案
Unit 9 Survival EnvironmentThinking AheadStudents are asked to discuss the following questions in groups. The reference answers for the questions are offered below:1. Do you think that the environment we are living in is getting better or worse? In what ways?I think the environment we are now living in is deteriorating steadily. There are many examples: degradation of air quality, pollution of water, loss of many plants and animals, widespread deforestation, global warming, overuse of plastic bags, etc.2. Many people tend to talk about “to protect the environment”. D o you agree? Why? What have you done in your day-to-day lives to protect the environment or not to harm our earth?To be honest, I don’t agree. Many of activities which we call “to protect the environment” are actually not harming the earth or harming our planet less, for example, driving fewer miles each week, using less non-degradable plastic bags and so on.Things we could do in our day-to-day lives:⏹Install a water-saving toilet.⏹Turn off the water when brushing teeth, shaving, etc.⏹Run the dishwasher only with a full load.⏹Replace light bulbs with compact fluorescent bulbs or otherenergy efficient light bulbs.⏹Buy energy efficient appliances.⏹Keep your refrigerator’s temperatu re set at a medium-cooltemperature.⏹Use double-pane windows to better insulate your home.⏹Turn off lights when not in use.⏹Turn off your computer, television, etc. when not in use.⏹Make sure your printer paper is 100% post-consumer recycledpaper. The paper industry is the third greatest contributor to global warming emissions.⏹Use email instead of snail mail for informal letters.⏹Print or copy on both sides of the paper whenever possible.⏹Look to yard sales, thrift stores and antique shops for usedhouseh old goods instead of buying new ones. “One man’s trash is another man’s treasure.”⏹Recycle everything: newspapers, cell phones, electronics, cans,glass, aluminum, motor oil, scrap metal, etc.⏹Use the stairs instead of the elevator whenever possible.⏹Buy a fuel-efficient/eco-friendly car.⏹Carpool or use public transit whenever possible.⏹Ride your bike or walk.Encourage your family, friends, and neighbors to save resources.(From /dept_Water/information_resources/Saving_water/110_Ways_to_Save_Water.asp)Part I Video TimeIn this part, students will have 2 tasks to accomplish.Task 1In task 1, students will watch a video clip from Obama about energy and environment, and then do the exercises as required. Before watching, they are supposed to read the words, expressions and cultural notes related to the video.TranscriptBarack Obama: Energy and EnvironmentThe eyes of the world have always turned to this nation as the last bestowal of the earth. From the moment I take office as president, I willcall together scientists and entrepreneurs; heads of industry and labor; Democrats, Republicans and Americans from all walks of life to help develop and deploy the next generation of energy that will allow us to build the next genera tion’s economy.The days of the debate about whether or not the globe is getting warmer are over. We know that global warming is real, that if we don’t do anything about global climate change, that we could see catastrophic results.Right now we could increase the fuel efficiency standard to our cars to 43 miles a gallon, if we increase our fuel efficiency to 43 miles a gallon, then we will import zero oil from the Middle East. That’s something that we could do right now.We take a national low-carbon fuel standard and increase fuel efficiency standards. We could take the equivalent of 50 million cars worth of pollution off the road by the year 2020. The question is not if a renewable energy economy will thrive in the future, it’s where. And if we want that place to be the United States of America, we can no longer afford to wait. You say 20% of our energy would come from new more sources like wind, like solar, like biomass, like tidal energy. And by setting those high standards, suddenly, you start to see more investment in these areas, technology improves and over the long run, you start to see significant changes. We’re just up to understand we get more obligationsto the next generation, to make sure they’ve got a planet which is sustainable and admirable the same way we inherit the sustainable and admirable planet from our parents, and our grandparents. And I think young people, in particular, recognize the importance of this issue, and in the long day-to-day lives, they are trying to make sure they are carbon neutral, make sure they are not wasteful, and almost things add up.I want o ur children and our children’s children to point to this generation and this moment as the time when America found its way again. As the time when America overcame the division and the politics and the pettiness of an earlier era so that a new generation could come together and take on the most urgent challenge of this era. I am running for the presidency of the United States to lead us toward this new era.(From /videosearch?q=Energy+and+Enviroment&hl=en&emb=1&aq=-1&oq=#) Key to ExercisesExercise 1 Watching for Specific InformationStudents are asked to watch the video clip and fill in the blanks with the missing information.1) The eyes of the world have always turned to this nation as the lastbestowal of the earth.2) We know that global warming is real, that if we don’t do anything about global climate change, that we could see catastrophic results.3) Right now we could increase the fuel efficiency standard of our car to 43 miles a gallon, if we increase the fuel efficiency to 43 miles a gallon, then we will import zero oil from the Middle East.4) You say 20% of our energy would come from new more sources like wind, like solar, like biomass, like tidal energy.5) And by setting those high standards, suddenly, you start to see more investment in these areas, technology improves and over the long run, you start to see significant changes.6) And I think young people, in particular, recognize the importance of this issue, and in the long day-to-day lives, they are trying to make sure they are carbon neutral, make sure they are not wasteful, and almost things add up.Exercise 2 Group DiscussionStudents are asked to watch the video clip again and then discuss in groups the viewpoints of Obama on energy and environment.Suggested AnswerFrom the video clip, we can find that what Barack Obama says about the United States reaching out to the world, in a spirit of real cooperation and leadership on climate-chang e issues, is very important. It’s time, at last, for a new president to reverse Washington’s arrogant and bone-headed attitudes of the past seven and a half years. In this clip, Obama emphasized his commitment to investing in clean technology, saying that new technology from the United States can help other countries to fight climate change. In a word, we all should assume the responsibility of our generation in protecting the environment and leave a bright and clean world to our future generation.Task 2In task 2, students will watch a video clip about global warming in the world and then do the exercises as required. Before watching, they are supposed to read the words, expressions and cultural notes related to the video.TranscriptGlobal WarmingFor 2.5 million years, the earth climate has fluctuated, cycling from ice ages to warmer periods. But in the last century, the planet’s temperature has risen unusually fast—about 1.2 to 1.4 degrees Fahrenheit. Scientists believe it’s human’s activity that’s driving the temperatures up;a process known as global warming. Ever since the industrial revolution began, factories, power plants and eventually, cars, have burned fossil fuels such as oil and coal, releasing huge amounts of carbon dioxide and other gases into the atmosphere. These green house gases trap heat near the earth through a naturally occurring process called the greenhouse effect. The greenhouse effect begins with the sun and the energy it radiates to the earth. The earth and the atmosphere absorb some of this energy, while the rest is radiated back into space. Naturally occurring gases in the atmosphere trap some of this energy and reflect it back, warming the earth. Scientists now believe that the greenhouse effect is being intensified by the extra greenhouse gases that humans have released. Evidence for global warming includes a recent string of very warm years. Scientists report that 1998 was the warmest year in measured history, with 2005 coming in second. Meanwhile, readings taken from ice cores show that the greenhouse gases, carbon dioxide and methane have hittheir highest level in the past 420,000 years.Arctic sea ice is also shrinking. According to NASA studies, the extent of Arctic sea ice has declined about 10% in the last 30 years. As long as industrialized nations consume energy and developing countries increase their fossil fuel consumption, the concentration of greenhouse gases in the atmosphere will continue to rise. Researchers predict that temperatures will increase about 2 to 10 degrees Fahrenheit by the end of the century. What’s less certain is what rising temperatures mean for the planet. Some climate models predict subtle changes. Others forecast rising sea level which could flood coastal areas around the world. Weather patterns could change, making hurricanes more frequent. Severe droughts could become more common in warm areas and species unable to adapt to the changing conditions would face extinction.Although much remains to be learned about global warming, many organizations advocate cutting greenhouse gas emissions to reduce the impact of global warming. Consumers can help. By saving energy around the house, switching to compact fluorescent light bulb s and driving fewer miles in the car each week. These simple changes may help keep the earth cooler in the future.(From /b/16866413-1394741582.html) Key to ExercisesExercise 1 Making a Sound JudgmentStudents are asked to watch the video clip and decide whether the following statements are true (T) or false (F).T 1) For 2.5 million years, the earth climate has fluctuated, cycling from ice ages to warmer periodsF 2) Ever since the industrial revolution began, factories, power plantsand eventually, cars, have burned fossil fuels such as oil and coal,releasing huge amounts of carbon monoxide and other gases intothe atmosphere.F 3) Scientists report that 1988 was the warmest year in measuredhistory, with 2005 coming in second.T 4) According to NASA studies, the extent of Arctic sea ice has declined about 10% in the last 30 years.F 5) Researchers predict that the temperatures will increase about 2 to10 degrees Fahrenheit by the end of the next century.Exercise 2 Information SharingStudents are asked to try to list the things in their daily lives that couldresult in global warming and then discuss with other students. Suggested Answers●Livestock farming contributes more to global warming than all otherfactors combined. While it takes on average 24 gallons of water to create one pound vegetable, 5,200 gallons of water are needed to create one pound of beef, which strains extremely the water resources as we hear more and more in the news. Comparably, it takes two calories of fuel to produce one calorie of soybean, 54 calories of fuel are necessary to generate one calorie from beef.●Deforestation is another big factor. The livestock growth has createdseven times more deforestation than the one caused by all other human activities. Water pollution, heath issues, lost of biodiversity, the release of toxins, antibiotics, pesticides, sewage, air pollution...are other factors that make livestock farming so detrimental to the environment.●Researchers evaluate that 2.5 acres of land can meet the foodrequirement of twenty two vegetarians, but only two people eating meat, chicken, eggs or dairy products.●Each time you drive, your car is emitting carbon monoxide. Multiplythat pollution with the hundreds of millions of other vehicles and youcan clearly see that driving a fuel engine vehicle does add to global warming.Part II Listening ActivitiesIn this part, students will have 3 listening tasks to accomplish.Task 1In task 1, students will listen to a report about solar energy and then do the exercises as required. Before listening, they are supposed to read the words, expressions and cultural notes related to the report.TapescriptCemetery Is Solar SourceCatalans are famous throughout Spain for their spirit of innovation. That ingenuity has recently been extended to the creation of what, the Associated Press reports, is the Barcelonan area’s largest solar energy plant. The solar panels have been installed on top of several mausoleums at a cemetery located in the suburb of Santa Coloma de Gramanet. It isone of a few open sunny places in the crowded city of more than 120,000 where space can be at a premium.“The project includes the installation of 462 solar panels over an area of 700 square meters that generate 202 kilowatts of power. To put it in colloquial terms, this amounts to the amount of electricity that 60 families consume in a year.”The city has several other solar parks which have mostly been installed on top of the buildings, but the cemetery is by far the largest. That does not seem to worry Juan Arroyo Garcia who is a regular visitor to the cemetery.“When I learned from the media that they were going to install solar panels in the c emetery, I thought that it wasn’t a bad idea at all. It doesn’t spoil the landscape. On the othe r hand, they don’t disturb our private grief when we visit our deceased loved ones, and on the top of that all, we are talking about clean energy. I fully support this.”Garcia’s reaction reflects the community-wide support for the project even though there were some initial concerns.“The first reaction from the public was one of surprise. They didn’t understand why we put solar panels in the cemetery. They asked if they were built to light their homes. So when we explained to them why the panels were put there, they understood and thought that was a very good idea.”Row after row of solar panels now cover the tops of the mausoleums. They soak up the maximum amount of the sunshine as the panels almost face south.They are also tilted at a low angle, making them unobtrusive.“When I got here, I was really surprised, mainly because I hadn’t been here for a long time. I thought to myself, look at that—now they’ll be able to watch television and to get heating during the winter time. But when I learned about this initiative, then I thought it was a very good idea, because the energy generated here will provide electricity to many families. It is ingenious.”According to the Associated Press, the project helps reduce the level of carbon dioxide in the atmosphere by 62 tons each year. Authorities now hope to install solar plants in most cemeteries in Catalonia as well as elsewhere in Spain.(From /viewthread.php?tid=152361&extra=page%3D6) ExercisesExercise 1 Listening for DetailsStudents are asked to listen to the report and fill in the blanks with the missing information.1) The cemetery is one of a few open sunny places in the crowded city ofmore than 120,000 where space can be at a premium.2) The project includes the installation of 462 solar panels over an area of700 square meters that generate 202 kilowatts of power.3) The city has several other solar parks which have mostly been installedon top of the buildings, but the cemetery is by far the largest.Exercise 2 Listening for Specific InformationStudents are asked to listen to the report again and answer the following questions.1) What are Catalans famous for throughout Spain?The spirit of innovation.2) Where are these solar panels put?On the tops of the mausoleums.3) Which direction do these solar panels face?South.4) According to the Associated Press, how many tons of carbon dioxidein the atmosphere will be reduced each year?62 tons.Task 2In task 2, students will listen to a CNN news about cutting the emission of greenhouse gases from New York City and California State and then do the exercises as required. Before listening, they are supposed to read the words, expressions and cultural notes related to the news.TapescriptCutting the Greenhouse GasesUnidentified CNN Correspondent: It’s another Republican revolt. This time the battle is on global warming. California Governor Arnold Schwarzenegger and New York’s Mayor Michael Bloomberg have joined forces on the front lines.California Governor Arnold Schwarzenegger:You can see a perfect example of how much he’s getting done in New York, of how much we get done here in California, and how little is getting done in Washington. It is unbelievable. They are frozen.Unidentified CNN Correspondent: That slap at the federal government came while the pair toured a plant that makes alternative energy, namely hydrogen power. There, Bloomberg announced a plan to cut carbon dioxide and other greenhouse gases in New York City, while Schwarzenegger reminded the media he’s about to sign a bill which will cut California emissions of harmful gases 25 percent by the year 2020. Schwarzenegger is running for reelection this year, and it’s up to him, say California political watchers, to distance himself from President Bush, who is unpopular in this state. Many voters still remember that Schwarzenegger campaigned for President Bush in the last presidential race. They may also remember his 2003 campaign for governor, driving around in a Hummer, a gas-guzzler compared to most vehicles. The Governor’s Office says Schwarzenegger still owns four Hummers, but has not used them much since taking office. He’s often driven around by state vehicles.So will this new campaign help Arnold’s image?Unidentified Expert Analyst:Well, I mean, clearly California is our largest state. It’s the sixth or seventh largest economy in the world.New York is our largest city; it’s the financial capital of the world.The symbolic effect of the two of them getting together and saying this is a real issue and we’re going to show some leadership because Washington isn’t…Unidentified CNN Correspondent:Administration officials say the White House is addressing global warming through increased research and incentives to businesses to cut emissions.（From /TRANSCRIPTS/0609/22/sitroom.02.html）ExercisesExercise 1 Listening for Specific InformationStudents are asked to listen to the news and choose the best answers to the questions.1) B2) C3) DExercise 2 Listening for DetailsStudents are asked to listen to the news again and fill in the blanks with the missing information.1) It’s another Republican revolt. This time the battle is on global warming.2) Schwarzenegger is running for reelection this year, and it’s up to him,say California political watchers, to distance him from President Bush, who is unpopular in this state.3) They may also remember his 2003 campaign for governor, drivingaround in a Hummer, a gas-guzzler compared to most vehicles.4) Administration officials say the White House is addressing globalwarming through increased research and incentives to businesses to cut emissions.Additional ListeningIn this section, students will listen to a CNN news about water recycling in California and then do the exercises as required. Before listening, they are supposed to read the words, expressions and cultural notes related to the news.From the Toilet to the TapCNN’s Kara Finnstrom reports on Orange County, California’slatest source for water.Clean, clear water, it is in short supply here in Orange County, so any new source, like this one, is warmly welcomed. That is, if you can get password where this water comes from.That’s right—what’s now destined to become Orange County’s drinking water started out as sewer water, brown wastewater from toilets, dishwashers, bathtubs, you name it.“We’ve explained from the beginning, this is actually sewer water that’s been treated by the sanitation district and then purified even more by us, till it’s really uh, almost distilled water.”To do that, Orange County launched a first of its kind facility, a nearly half billion dollar reclamation plant that can turn 70 million gallons of treated sewage into drinking water every day.“It’s gonna become a model for the entire world, uh, Singapore has already built a smaller version of our exact plant, and there are several others around the United States that are being planned.”The plant runs sewage that would have been discharged to the sea through a three-step purification process. First, it heads through micro-filters to sift out solid matter.“Any solid particle, larger than, 1/300th the size of a human hair would remain on the outside.”Then it runs through another filter to remove any viruses or pharmaceuticals. And, finally, the water gets a purging bake in high intensity light—breaking down anything that’s left. The result?“Yeah, it tastes.”“H ow does it taste?”“It tastes like distilled water.”“How long ago was that s ewage?”“Probably abou t two days ago.”Soon, water officials won’t be the only ones tasting it. This water will now mix with groundwater and should run out of Orange County taps in as little as six months. The water must meet safety standards. One environmental group has reservations about what they call the limits of such tests.“It brings up concerns of what we’re looking for, what we’re not looking for, and what we don’t know”. While there is no doubt Southern California needs more water, some say this is a little hard to swallow. “Even though, I know that they’ve uh, filtered it 3 times, it’s just, just kind of creepy.”But many say the benefits just may outweigh the creepiness. “I think it’s about time we recycled everything.” That’s due, in part, to a massive campaign touting the benefits of less discharge to the sea, and more water for a thirsty Orange County.Kara Finnstrom for CNN, Orange County.(From /viewthread.php?tid=131623&extra=page%3D17)ExercisesExercise 1 Listening for Specific InformationStudents are asked to listen to the news and choose the best answers to the questions.1) C2) B3) CExercise 2 Oral PresentationAfter learning the process of treating sewer water in Orange County, students are asked to give more ways of preserving and saving water resources in their everyday lives.Suggested Answers1. There are a number of ways to save water, and they all start with you.2. When washing dishes by hand, don’t let the water run while rinsing.Fill one sink with wash water and the other with rinse water.3. Check your sprinkler system frequently and adjust sprinklers so onlyyour lawn is watered and not the house, sidewalk, or street.4. Run your washing machine and dishwasher only when they are full.5. Check your water meter and bill to track your water usage.6. Minimize evaporation by watering during the early morning hours,when temperatures are cooler and winds are lighter.7. If your shower can fill a one-gallon bucket in less than 20 seconds,then replace it with a water-efficient showerhead.8. Collect the water you use for rinsing produce and reuse it to water houseplants.9. We’re more likely to notice leaky faucets indoors, but don’t forget tocheck outdoor faucets, pipes, and hoses for leaks.10. When you shop for a new appliance, consider one offering cycle andload size adjustments. They are more water and energy-efficient than older appliances.11. Install low-volume toilets.12. When you clean your fish tank, use the water you’ve drained on yourplants. The water is rich in nitrogen and phosphorus, providing you with a free and effective fertilizer.13. Designate one glass for your drinking water each day. This will cutdown on the number of times you run your dishwasher.14. Don’t use running water to thaw food.15. Teach the children to turn the faucets off tightly after each use.16. Make sure you know where your master water shut-off valve islocated. This could save gallons of water and damage to your home ifa pipe were to burst.17. Turn off the water while you brush your teeth.18. Drop that tissue in the trash instead of flushing it and save gallons every time.19. Encourage your friends and neighbors to be part of a water-conscious community.20. Turn off the water while you shave.21. When you give your pet fresh water, don’t throw the old water downthe drain. Use it to water your trees or shrubs.22. While staying in a hotel or even at home, consider reusing your towels.23. Keep a bucket in the shower to catch water as it warms up or runs.Use this water to flush toilets or water plants.。

新人教版九年级英语unit9重点知识点Unit 9是新人教版九年级英语教材中的重要章节，本单元主要围绕环保主题展开，涉及了许多重要的知识点。
在这篇文章中，我将为大家详细介绍Unit 9的重点知识点。
首先，我们来看一下Unit 9中的语法知识。
本单元主要介绍了被动语态的用法。
被动语态是英语中一种常用的语法结构，它用来强调动作的接受者或者提前说明动作的主语。
在被动语态中，谓语动词由“be+过去分词”构成，根据时态的变化，be动词的形式也会发生变化。
例如，当我们要表达“这首歌被我听到了”时，可以用被动语态，即“This song was heard by me.”在实际应用中，被动语态可以更准确地表达某些动作的发生情况。
除了被动语态，Unit 9还介绍了一些重要的词汇和短语。
其中一个重要的词汇是“environment”，意为“环境”，在本单元中，我们学习了一些与环境保护相关的词汇，比如“pollution”（污染）、“recycle”（回收利用）和“waste”（废弃物）。
这些词汇在我们日常生活中非常重要，能够帮助我们更好地了解环境问题，并促使我们采取积极的行动保护环境。
另外一个重要的短语是“take action”，意为“采取行动”。

In the 9th unit of the 8th-grade English course, we are going to explore various aspects of the environment and understand how we can contribute to its conservation. This unit will cover topics such as pollution, endangered species, and climate change.1. Pollution:Pollution is a significant concern worldwide, affecting both the environment and human health. There are different types of pollution, including air pollution, water pollution, and noise pollution. Air pollution, caused by emissions from vehicles and factories, leads to respiratory issues and climate change. Water pollution, due to the release of industrial waste and improper disposal of litter, harms aquatic life and contaminates our water sources. Noise pollution disrupts wildlife and negatively affects human well-being. It is essential for us to understand the causes and effects of pollution to combat this pressing issue.2. Endangered Species:With the growing human population and increasing human activities, numerous species around the world are facing the risk of extinction. Factors such as habitat destruction, poaching, and climate change contribute to the endangerment of various plants and animals. For example, the destruction offorests threatens the survival of orangutans and other wildlife. We need to raise awareness and take proactive measures to protect and preserve endangered species to maintain the balance of our ecosystems.3. Climate Change:Climate change refers to long-term shifts in temperature and weather patterns. Human activities, particularly the burning of fossil fuels, have led to a significant increase in greenhouse gas emissions, resulting in global warming. The consequences of climate change include rising sea levels, extreme weather events, and the loss of habitats. It is crucial for us to reduce our carbon footprint by adopting sustainable practices like using renewable energy sources, conserving water, and promoting eco-friendly transportation methods.4. Environmental Conservation:Preserving and conserving the environment is a responsibility that falls upon each individual. We can make a positive impact by adopting environmentally friendly practices in our daily lives. For instance, we can reduce, reuse, and recycle to minimize waste generation. Additionally, planting trees and participating in community clean-up events can help restore and maintain the beauty of our surroundings. By being mindful of our actions, we can contribute to the sustainable development of our planet.Conclusion:Understanding the importance of the environment and taking action towards its conservation is crucial in today's world. Through the study of pollution, endangered species, and climate change in the 9th unit of ourEnglish course, we have gained valuable knowledge on these pressing issues. By implementing sustainable practices and raising awareness, we can make a positive difference for the environment and secure a better future for generations to come. Let us strive together to protect and preserve our precious planet.。

Well, Alex, thanks for your ideas.Alex: It is a pleasure.Exercise 2Directions: Listen to the conversation again and fill in the blanks with the missing words.Part C PassagesPassage 1LandfillsDirections: In this part, you will hear a passage. Listen carefully and choose the right answers to the questions given below.Americans generate trash at an astonishing rate of 4.6 pounds per day per person, which translates to 250 million tons per year. This is almost twice as much trash per person as most other major countries like Germany, Japan. What happens to this trash? Some gets recycled or recovered and some is burned, but the majority is buried in landfills.Of the 251 million tons of trash, or solid waste, generated in the United States in 2006, about 81.8 million tons, or 32.5 percent, was either recycled or composted. Before recycling, trash mostly consists of paper products, yard clippings, plastics and food waste.The trash production in the United States has almost tripled since 1960. This trash is handled in various ways. About 32.5 percent of the trash is recycled or composted, 12.5 percent is burned and 55 percent is buried in landfills. The amount of trash buried in landfills has doubled since 1960. The United States ranks about in the middle of the major countries in landfill disposal. The United Kingdom ranks highest, burying about 90 percent of its solid waste in landfills.The purpose of a landfill is to bury the trash in such a way that it will be isolated from groundwater, will be kept dry and will not be in contact with air. Under these conditions, trash will not decompose much.In order to build a landfill, the environmental impact study should be done first, and then get the permits and raise the money. And also, access roads to the landfill site must be built if they do not already exist. These roads will be used by construction equipment, sanitation services and the general public. After roads have been built, then the construction of a landfill can be initiated.Passage 2No Butts about ItDirections: In this part you will hear another passage. Listen carefully and answer the following questions by completing the sentences given below.My sister Alli and I have been trying to get people to stop dropping cigarette butts for seven years.One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people stop dropping butts. We called it “No Butts about It”.At first, we drew pictures with “The Earth is not your ashtray” written on them. We put the pictures around our hometown in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don’t think that dropping butts hurts the Earth. But it does! All rubbish does.Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn’t have to drop butts.At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other “No Butts about It” groups in America. And there are even groups in England, Australia and India!Many newspapers have written about my sister and I over the last seven years. And we have won many prizes for our good work. But we are not interested in prizes. We just want to make the Earth a better and cleaner place for animals, plants and people. One day it will be.。
