What Environmental Disaster? We have developed a huge and thriving society; and in the process we deforest huge sections of land for living and livestock This decreases oxygen and increases carbon dioxide in the atmosphere; possibly adding to global warming though the greenhouse This mass population produces mass amounts of waste, so to deal with that we just throw it into the ground, which in turn contaminates our water supply and contributes to further We develop motorized transportation; and then burn non-renewable fossil fuels that put lead, carbon monoxide, sulfur and nitrogen oxides, ozone, excess carbon dioxide, and other harmful particulates into the atmosphere (Skjel & Whorton 95-108) This produces dangers like smog and cancer and contributes to global In the production of fuel we exhaust oil reserves and pollute the oceans through spills from This endangers wilderness and We produce an inert, easily producible propellant for aerosols; and then realize it's only inert on the Once it's bombarded by UV ray in the upper atmosphere it releases a highly destructive ion that wreaks havoc on the protective ozone layer shielding us from those same deadly UV rays, creating a hole in the layer allowing the radiation through, increasing cancer and other genetic We build rockets capable of going into space and breaking the earth's gravitational pull; and then immediately start to pollute this new environment with spent rockets and boosters along with other miscellaneous particles of debris (Curran and Haw 3) Michael Crichton writes, "What we call nature is a complex system of far greater subtlety than we are willing to We make a simplified view of nature and then botch it all You have to understand what you don't How many times must the point be made? How many times must we see the evidence? We build the Aswan Dam and claim it is going to revitalize the Instead, it destroys the fertile Nile Delta, produces parasitic infestation, and wrecks the Egyptian economy" (Jurassic Park 91) To the common person our current situation contains little All the advancement and improvements have done little to further our With each one has come a new environmental You almost need to evaluate each situation in terms of positives and However, at the root of all this chaos you'll find anthropocentrism, a human centered way of This way of thinking as an attitude, and moral theory, centers on humans as the highest of the significant The theory views nature and the environment in terms of their use value for humans only (Michaels 7) So all of the above developments with costs can be justified through their usefulness for The human centered ethic is deeply rooted in the past through the ancient Greek and Roman To pursue further development based on this ethic would be With our current numbers of population and rate of growth we're just asking for an environmental catastrophe of the highest magnitude to act as a wake up Granted that a great deal of the population realizes that unless action is taken today then we'll have to face that disaster The principle question is how to go about alleviating and repairing the damage we've already We also need to address how to prevent doing further damage for the sake of future The only problem with this view is that it is still a human centered It still sees the environment as a thing to be utilized by humans for their own It doesn't do The problems aren't getting Better ways of doing things are being researched, but the underlying problem is not receiving any So the environmental downward spiral is only slowed down and is not We've still got the same To take the conservationist attitude further you would see all sentient beings as holding moral standing and due This includes most of the animals in the world; any animal capable of experiencing pleasure and Through these experiences you form the basis for the extended moral If the animals perish through their habitat's destruction or outside influences, then their future pleasures will no longer When you take into account whole societies and communities of animals then the added value to the environment increases exponentially as you combine their happiness with the happiness never experienced by their future generations (Singer 275-276) So by taking this viewpoint you place even more intrinsic value on the environment through the experiences of all sentient animals But at a time when our behavior may well lead us to extinction, I see no reason to assume that we have any awareness at We are stubborn, self-destructive Any other view of our species is just a self-congratulatory delusion" (The Lost World 7-8) Granted this does not present a case for sentience on the basis of pain pleasure, but it does present an interesting way to think about classifying So you can see drawing the cut off line for even lower animals could present considerable You have trouble reaching an adequate definition of "" You are now facing how much awareness a creature has to perceive pain and pleasure along with joy from anticipation of future events to consider it morally If a cat is significant, but not a fish, what makes the cat a moral patient while the fish is not? Where is there a difference? There is a problem of arbitrarily assigning moral value when actual feelings and emotions are beyond To go a step further away from human sentience you would hold all living thing to be of moral This would then bring plants and non-sentient animals into the This view holds life as the ultimate intrinsic Beings have moral value in just being So life is viewed as an intrinsic good, and no verifying pleasures or pains being experienced are needed to allot this Anything living is held with a reverence for that life (Singer 277-278) 2】The Environmental Revolution - We Can Make a Difference! Since the first time having blown bubbles in my Open Water class, I've logged over 100 This love for diving has evolved into an intense passion towards protecting the ocean, and all of its I've chosen to put my love for the ocean into action, as an Actually, this passion extends out towards efforts that look to help all the planetary domains gain As such, I appreciate when others take the time educate me on those other realms for which I know less To be an environmentalist, one must choose the cause which resonates within ones sole, and run with One must be willing to educate people about the environment while being open to education from those people who support other Together we can help each other towards learning how to become a true "Environmentalist" We must all encourage positive collaboration and education as opposed to being against For example, sharks are being decimated to near extinction simply for their The fins are used to make Shark Fin soup, a delicacy popular particularly in Taiwan and S It would be easy to blame these communities for creating the However, in conversing with Asian environmentalists, they liken the culture around eating Shark Fin soup to the culture surrounding Americans eating turkey for Thanksgiving There are ongoing efforts to educate these people, by members of their own community, on just how dangerous this cultural practice is and the devastating impact this could have on their (our) world if all the sharks were to disappear as a Environmentalists everywhere are making a difference! Famous restaurants have taken endangered Swordfish off their menus, these same restaurants are buying wild-caught salmon (and boosting the economy of local fisheries in the process), laundromats have started selling green detergent, this just to name a few of these enlightened This is how the "Environmentalist" can begin the Just find something you believe in and make a One by one, we can make our planet a cleaner place to live, steeped in healthy bio-diversity for generations to 3Giving 1% to Protect Our Environment Though most of the world's surface is covered by water, since the Earth is so large relative to human horizons, there doesn't appear to be a shortage of However, when one begins to think of land in terms of a human resource, , a producer of food, a provider of wood, an expanse for passage, one realizes that many portions are either too lacking in nutrients, too high in elevation, too prone to flooding, or too cold or ice-ridden for extensive Furthermore, habitable lands are becoming less abundant due to desertification (the expansion of deserts due to the misuse of land), agricultural expansions and rising sea Since humans aren't the only species that need land, it isn't surprising that this resource is becoming limited for other forms of life In part as a result of this added stress on living things, we are also witnessing extinctions of grand proportions-at a rate of many thousands species per Since these losses are largely due to human actions, such as deforestation and non-native species introduction, many are beginning to pay attention to how we use and protect Recent ecological research has also recently provided a message of hope concerning the future well-being of life on this In the world today, scientists estimate that the Earth is losing at least 1 percent of species every ten years, and the percentage loss may be close to 5 Even if only the lower rate persists, the Earth will have lost near half of its biological diversity by Can this be possible? Many esteemed scientists think While the future appears bleak, several recent insights tell us that we have the potential to significantly reduce what amounts to a biotic holocaust, one not witnessed on Earth for over 60,000,000 While there are hopeful signs in the area of human activities (such as increased acreage of nature preserves and national parks), the hope of which I speak of here stems from specific characteristics of the other forms of life which may enable us to mutually coexist in the long The Earth's organisms are wonderfully varied in size, shape, function, behavior, and genetic One only need to consider that there are ~ 15,000 species of butterflies and ~50,000 species of mushrooms worldwide to begin to fathom the immensity of variety that this planet Yet, as different as the species come, the bulk of living things are also similar in a couple of very important Most living things live in relatively small regions and do not travel far from where they or their parents were In fact, recent biological and ecological work has determined that most land species are very particular about where they As opposed to humans whose choice of home is largely driven by economic and political forces (mobility driven by availability of wealth or forced relocation), flora and fauna find themselves in locations for which they are We now know that many species of insects and plants have a very restricted range in which they Very few organisms are ubiquitous like we It goes without saying that you aren't going to find a Great Blue Heron or a Grizzly visiting Antarctica or climbing M Everest; yet you might find the snow bear (recently discovered and previously known as the Abominable Snowman) doing the Recognizing that most living things are rather localized during their lifetimes has profound implications, both hopeful and On the one hand, it suggests that we can learn a lot about species by parking our scientific minds in specific On the other hand, it means that if we destroy even small areas of the globe we are likely causing great and even irreversible destruction to the species that are found We have also determined that there are specific locations on our planet where a disproportionate number of species For our species, Asia serves as the homeland for In fact more than 60 percent of humans lives on this largest of continents (which only makes up 24 percent of the land surface on the planet) With other life forms, geographic concentrations sometimes defy We only recently became aware that the vast majority of terrestrial (as distinguished from oceanic or riparian) species collectively live on just 1 percent of the Earth's land (If humans lived at a comparable concentration level, we'd all have to cluster together in an area roughly the size of Antarctica or twice that of A) This mind-blowing realization has prompted those that have been struggling to protect organisms a new way of thinking about such They have concluded that if we humans could somehow find a way to avoid disturbing just 1-2 percent of the land surface, nearly 70 percent of the world's terrestrial species might be able to Recently some conservationists have refocused their attention on these unique The regions of the globe that contain such a splendid array of biological diversity have been named "hot spots," a name that communicates their critical In what has to be the most beautiful books I have seen, Hotspots represents the collective work of scientists Russ and Cristina Mittermeier and Norman Myers as well as photographer Patricio Robles G In this oversized volume, these four scholars have assembled more than three hundred vivid photographs of some of the world's endangered species and threatened These absolutely breath-taking images come from the what they refer to as "the 25 most critically important regions" in the These regions originally constituted almost 12 percent of the world's land surface but now, due to human pressure at many levels, only a little more than 1 percent remains What makes these locations, which are found on all continents except Antarctica, so "hot" is that they are home to hordes of the Earth's plants and animals and they face imminent danger from a variety of human The Hotshot authors and others strongly believe that the global community can do wonders if these areas move to the top of our priority But what will have to happen for these spots to be protected? There are no simple answers to this central Unfortunately, those of us in the United States who have the luxury of time to even ponder such questions, face many obvious First, nearly all of the hotspots are located outside of our territorial boundaries, exceptions being the forests of Oregon and California as well as portions of Southern Florida (namely the Keys and the Everglades) Key hotspots are found in New Zealand, Madagascar, and Indonesia as well as the continental parts of south-east A Obviously we cannot expect that we will be able to force other countries to enact and enforce laws that will greatly reduce biological Yet, while many other countries have ratified the Biodiversity Treaty that was drafted at the 1992 Rio Earth Summit, it has never reached the floors of the US Congress for a vote; Canada, Japan, and the European Union are among those to ratify By this inaction our nation apparently lacks the wherewithal to support global conservation efforts as a matter of However, given that the wealthy nations in concert with international banks promote unsustainable extraction of resources in the world's developing countries, it would appear that we have an obligation to do If our national policy makers are unwilling to commit themselves to the protection of global ecosystems and species, we still have ourselves to look to for sources of positive All of us have tremendous purchasing power, especially in comparison to the majority of the other human residents on this planet; Barry Bearak, a Pulitzer Prize-winner journalist who recently spoke at Knox College's convocation, referred to the residents of the United States as "filthy rich," a conclusion he came to after spending a great deal of time in the poorer regions of the world, particularly Afghanistan and I What we buy makes a The environmental campaign to support shade coffee rather than sun coffee is just one of many attempts for the consumer to support sustainable practices in regions of great ecological According to the Northwest Shad Coffee Campaign, shade coffee agricultural allows for the extraction of a desired resource but at the same time allows between 3-8 times as many birds species to persist not to mention many more mid-size mammals as well as amphibians and Coffee is also a particularly important commodity in terms of the health of ecological systems because the countries that produce the bulk of it are precisely the same countries that are home to the majority of the world's species; the countries of Brazil, Bolivia, Indonesia, Vietnam collectively produce ~40 percent of the 17 billion pounds of coffee that are harvested each year (folks, that's more than 3 pounds per person!) Burdensome debts also force many developing countries to endlessly delay infrastructure Debt-for-nature swaps, an idea proposed by D Thomas Lovejoy of the World Wildlife Federation in the mid-1980s, have enabled poor countries to relieve foreign debt and international nongovernmental organizations (NGOs) to increase commitment to conservation programs both at the same In these swaps, NGOs pay off a poor country's debt to a bank or well-to-do country at greatly reduced costs in order to establish agreements for investment in national parks, for While not a cure-all, these efforts have begun the paradigm shift from unabated expansion and unhealthy extraction to one supportive of saving natural ecosystems and securing the health and welfare of all human Threats to these locations represent massive scale intrusions taken by societies found on every Unfortunately, there is so much that will be lost if these "special" places aren't quickly protected from future On the bright side though, so much of the world's genetic diversity lives in just a couple handfuls of "hotspots" that if these locations were saved hordes of species would be able to persist into the next The time is now to respond to this fairly recent observation and It is time for the world to begin to act like a civilized 21st Century It is incumbent upon us, those with time and wealth, to maintain the momentum that others have The masses of life forms are relying on us to make the best attempt at this daunting yet critical Hopefully our species will be sensible enough to leave at least 1 percent of land alone, so that other life forms may continue to Do we need all 100 percent? 写不下了,如果觉得不够,邮箱可否留一下,我继续补充

污水再生利用有关问题的探讨关键词 污水 回用问题 分析摘要:用水量的增加对现有水资源的压力越来越大,人们开始意识到污水回用是一种非常可靠的供水水源,成功的污水回用工程越来越多,供水和污水处理行业越来越意识到污水再生利用的 经济 和环境效益。为满足高水质标准而进行污水处理厂更新改造的成本不断增加,污水回用越来越受到人们的重视。   一、污水回用的意义     污水回用在发达国家已得到广泛应用,而且越来越多的行业已经开始利用处理后的污水。人口增加和用水量的增加对现有水资源的压力越来越大;人们开始意识到污水回用是一种非常可靠的供水源;成功的污水回用工程越来越多;供水和污水处理行业越来越意识到污水回用的经济和环境效益;蓄水工程的环境和经济成本越来越高;人们逐渐意识到与过度用水有关的环境影响;趋向于回收成本水价制度的引入促进了污水的回用;为满足高水质标准而进行污水处理厂更新改造的成本不断增加。    二、污水可持续利用的领域      (一) 工业 用水的回用   从理论上说,经处理的污水可以回用于各种不需要符合饮用水水质要求的工业 企业 。各种工业生产过程中的冷却水、锅炉用水、生产和加工用水、清洗和辅助用水(如除尘和浇地)等,都可以利用经处理的污水。可以使用经过处理的污水的行业包括商业洗车、造纸厂、矿山、石油精炼厂、电站、商业洗衣、道路建设企业、 旅游 点、酿酒厂,以及混凝土、砖、纺织品、金属及涂料的生产厂。日本近40%经处理的市政污水被用于工业用途,而美国的佛罗里达州和加利福尼亚洲分别为2%和5%。   (二)居民及社区的非饮用水回用   限制污水回用于居民和社区非饮用水的因素包括:健康因素;缺乏相关的指导;更新和建设水处理和供水设施的成本;处理过的污水水源的距离;灌溉需水的季节性变化;灌溉方面的技术性问题和环境的可持续性。   (三)间接的饮用水循环   间接的饮用水循环是将一部分经过处理的污水注入已有的供水水源中,通过水体的稀释作用,以及长时间的存放和取水后的处理,确保它满足可饮用水的水质标准。 缺乏对水质和水处理知识的了解、社会的理解和对健康的关注,可能是间接饮用水循环的最大障碍。   三、污水的可持续回用分析    制定可持续污水回用战略必须坚持以下基本原则:一是回用水的水质必须满足不同用水要求的原则;二是污水回用必须符合生态可持续 发展 要求的原则;三是在污水回用决策方面必须强调适当的健康、环境和经济因素的原则;四是污水回用项目必须是社会所需要的原则;五是污水回用必须作为总的水管理一部分的原则;六是污水回用的决策程序必须透明的原则;七是鼓励社会参与污水回用规划、开发和实施的原则;八是社会应可以得到有关污水回用可靠信息的原则。依据上述原则,应为实施可持续污水回用战略制定相应的行动计划,包括:修订或颁布 法律 ;制定回用指南和标准;提供技术支持与培训;加强宣传,提高对污水回用的了解;对关键领域与技术的研究提供支持;建设污水回用示范项目;积极支持污水回用项目;广泛合作,实施污水回用战略。   (一)从立法上支持污水回用   应该从立法上建立鼓励和支持污水回用的制度。首先应对国家现有相关立法的适用性进行评价,确定哪些方面不利于污水的回用,并对这些方面进行修订;没有涉及到的,应通过颁布新的法律法规来完善。美国加利福尼亚洲在《安全饮用水法》、《水回用法》和《加利福尼亚洲管理法》中,对污水回用的准则、领域、水处理、水质要求等方面都作了详细的规定。 中国论文联盟   (二)制定污水回用的 科学 标准   应在进行详细的咨询和研究后,制定污水回用指南。这些指南应能够为污水用水户提供有关回用项目规划、设计和运行方面的指导指南应涉及污水回用的各个领域,如利用污水灌溉牧场和作物,灌溉城市公园、花园、运动场和休息场所等,浇灌高尔夫球场,将污水回用于 工业 目的,分质供水,用于娱乐目的和间接饮用水循环,等等。对有关的标准要进行评价,特别是水质标准,并根据评价的结果修改现有的标准或制定新的标准。美国加利福尼亚洲污水回用准则就详细地规定了经不同处理的污水在灌溉、蓄水、冷却用水及其他用水方面的适用范围。   (三)在技术上对污水回用提供支持   政府部门应鼓励和促进 教育 机构、行业和其他培训组织进行有关污水回用工程设计、运行、维护、管理、技术及污水利用方面的培训,而且应为这样的培训提供支持,使服务商和用水户掌握必要的知识和技能通过有关污水回用的宣传材料和因特网等手段向用水户提供有关安全用水的信息,包括立法、指南与标准、培训课程、研讨会及研究成果方面的信息。

老师帮你制定课题方向之后,你或者你的小组在调查研究的基础上撰写的申请老师批准开始论文写作的选题计划。它主要说明这个课题应该进行研究,自己有条件进行研究以及准备如何开展研究等问题,也可以说是对课题的论证和设计。 一般老师会给你一个标准格式,里面有如何撰写开题的要点!根据你的题目,你收集的资料将你的写作思路按照格式写出来!

污水再生利用有关问题的探讨关键词 污水 回用问题 分析摘要:用水量的增加对现有水资源的压力越来越大,人们开始意识到污水回用是一种非常可靠的供水水源,成功的污水回用工程越来越多,供水和污水处理行业越来越意识到污水再生利用的 经济 和环境效益。为满足高水质标准而进行污水处理厂更新改造的成本不断增加,污水回用越来越受到人们的重视。   一、污水回用的意义     污水回用在发达国家已得到广泛应用,而且越来越多的行业已经开始利用处理后的污水。人口增加和用水量的增加对现有水资源的压力越来越大;人们开始意识到污水回用是一种非常可靠的供水源;成功的污水回用工程越来越多;供水和污水处理行业越来越意识到污水回用的经济和环境效益;蓄水工程的环境和经济成本越来越高;人们逐渐意识到与过度用水有关的环境影响;趋向于回收成本水价制度的引入促进了污水的回用;为满足高水质标准而进行污水处理厂更新改造的成本不断增加。    二、污水可持续利用的领域      (一) 工业 用水的回用   从理论上说,经处理的污水可以回用于各种不需要符合饮用水水质要求的工业 企业 。各种工业生产过程中的冷却水、锅炉用水、生产和加工用水、清洗和辅助用水(如除尘和浇地)等,都可以利用经处理的污水。可以使用经过处理的污水的行业包括商业洗车、造纸厂、矿山、石油精炼厂、电站、商业洗衣、道路建设企业、 旅游 点、酿酒厂,以及混凝土、砖、纺织品、金属及涂料的生产厂。日本近40%经处理的市政污水被用于工业用途,而美国的佛罗里达州和加利福尼亚洲分别为2%和5%。   (二)居民及社区的非饮用水回用   限制污水回用于居民和社区非饮用水的因素包括:健康因素;缺乏相关的指导;更新和建设水处理和供水设施的成本;处理过的污水水源的距离;灌溉需水的季节性变化;灌溉方面的技术性问题和环境的可持续性。   (三)间接的饮用水循环   间接的饮用水循环是将一部分经过处理的污水注入已有的供水水源中,通过水体的稀释作用,以及长时间的存放和取水后的处理,确保它满足可饮用水的水质标准。 缺乏对水质和水处理知识的了解、社会的理解和对健康的关注,可能是间接饮用水循环的最大障碍。   三、污水的可持续回用分析    制定可持续污水回用战略必须坚持以下基本原则:一是回用水的水质必须满足不同用水要求的原则;二是污水回用必须符合生态可持续 发展 要求的原则;三是在污水回用决策方面必须强调适当的健康、环境和经济因素的原则;四是污水回用项目必须是社会所需要的原则;五是污水回用必须作为总的水管理一部分的原则;六是污水回用的决策程序必须透明的原则;七是鼓励社会参与污水回用规划、开发和实施的原则;八是社会应可以得到有关污水回用可靠信息的原则。依据上述原则,应为实施可持续污水回用战略制定相应的行动计划,包括:修订或颁布 法律 ;制定回用指南和标准;提供技术支持与培训;加强宣传,提高对污水回用的了解;对关键领域与技术的研究提供支持;建设污水回用示范项目;积极支持污水回用项目;广泛合作,实施污水回用战略。   (一)从立法上支持污水回用   应该从立法上建立鼓励和支持污水回用的制度。首先应对国家现有相关立法的适用性进行评价,确定哪些方面不利于污水的回用,并对这些方面进行修订;没有涉及到的,应通过颁布新的法律法规来完善。美国加利福尼亚洲在《安全饮用水法》、《水回用法》和《加利福尼亚洲管理法》中,对污水回用的准则、领域、水处理、水质要求等方面都作了详细的规定。 中国论文联盟   (二)制定污水回用的 科学 标准   应在进行详细的咨询和研究后,制定污水回用指南。这些指南应能够为污水用水户提供有关回用项目规划、设计和运行方面的指导指南应涉及污水回用的各个领域,如利用污水灌溉牧场和作物,灌溉城市公园、花园、运动场和休息场所等,浇灌高尔夫球场,将污水回用于 工业 目的,分质供水,用于娱乐目的和间接饮用水循环,等等。对有关的标准要进行评价,特别是水质标准,并根据评价的结果修改现有的标准或制定新的标准。美国加利福尼亚洲污水回用准则就详细地规定了经不同处理的污水在灌溉、蓄水、冷却用水及其他用水方面的适用范围。   (三)在技术上对污水回用提供支持   政府部门应鼓励和促进 教育 机构、行业和其他培训组织进行有关污水回用工程设计、运行、维护、管理、技术及污水利用方面的培训,而且应为这样的培训提供支持,使服务商和用水户掌握必要的知识和技能通过有关污水回用的宣传材料和因特网等手段向用水户提供有关安全用水的信息,包括立法、指南与标准、培训课程、研讨会及研究成果方面的信息。
