Environmental Science Chapter 1 Notes Environmental Problems, Their Causes, and Sustainability Essays Environmental Science Chapter 1 Notes Environmental Problems, Their Causes, and Sustainability Paper Environmental Science Chapter 1 Notes Environmental Problems, Their Causes, and Sustainability Paper Essay Topic: Notes From Underground Environmental Problems, Their Causes, and Sustainability Chapter 1 Case Study Living in an Exponential Age Exponential growth – concept in which a quantity increases at a constant rate per unit of time Global economic output is a rough measure of the human use of the earth’s resources Poverty affects environmental quality, from the poor depleting and degrading forests, grasslands, and wildlife Exponential growth plays a key role in five important and interconnected environmental issues: population growth, resource use and waste, poverty, loss of biological diversity, and global climate change Questions What keeps us alive? What is an environmentally sustainable society? How fast is the human population increasing? What are economic growth, economic development, and globalization? What are the earth’s main types of resources? How can they be depleted or degraded? What are the principal types of pollution? What can we do about pollution? Wha t are the basic causes of today’s environmental problems? How are these causes connected? Is our current course sustainable? What is environmentally sustainable development? Living More Sustainably 1-1 What Is the Difference between Environment, Ecology, and Environmental Science? Defining Some Basic Terms Environmental science is a study of how the earth works, how we interact with the earth, and how to deal with environmental problems. Environment – everything that affects a living organism (any unique form of life) Ecology – a biological science that studies the relationships between living organisms and their environment Environmental science – study that uses information from the physical sciences and social sciences to learn how the earth works, how we interact with the earth, and how to deal with environmental problems; it involves integrating ideas from the natural world and our cultural world Environmentalism – social movement dedicated to protecting the earth’s life support systems for us and oth er species What Keeps Us Alive? The Sun and the Earth’s Natural Capital All life and economies depend on energy from the sun (solar capital) and the earth’s resources and ecological services (natural capital) Solar capital – energy from the sun Solar energy – direct sunlight and indirect forms of renewable solar energy such as wind power, hydropower (energy from flowing water), and biomass (direct solar energy converted to chemical energy and stored in biological sources of energy such as wood) Natural resources / natural capital – resources and ecological services from the planet itself such as air, water, fishery, mineral, processes of natural purification, and recycling Biological income examples are renewable supplies of wood, wish, grassland, and underground water for drinking and irrigation What is an Environmentally Sustainable Society? One that Preserves Natural Capital and Lives Off Its Income An environmentally sustainable society meets all the basic resource needs of is people indefinitely without degrading or depleting the natural capital that supplies these resources Environmentally sustainable society – society that meets current needs of its people for food, clean water, clean air, shelter, and other basic resources without compromising the ability of future generations to meet their needs Living sustainably means living off natural income replenished by soils, plants, air, and water and not depleting or degrading the earth’s natural capital that supplies this biological income Protect your capital and live off the income it provides Population growth, economic growth, economic development, and globalization 1-2 How Rapidly Is the Human Population Growing? Pretty Fast The rate at which the world’s population is growing has slowed but is still growing pretty rapidly Currently the populati on is growing exponentially at a rate of ~1. 25% a year It is actually a lot (average increase of 219,000 people a day) What Is the Difference between Economic Growth and Economic Development? More Stuff and Better Living Standards Economic growth provides people with more goods and services and economic development uses economic growth to improve living standards Economic growth – an increase in the capacity of a country to provide people with goods and services, often requiring population growth, more production and consumption er person, or both Gross domestic product (GDP) – the annual market value of all goods and services produced by all firms and organizations, foreign and domestic, operating within a country; usually measures the economic growth Per capita GDP – the GDP divided by the total population at midyear; indicator of standard of living Economic development – the improvement of living standards by economic growth What Is the Difference bet ween Economic Growth and Economic Development? More Stuff and Better Living Standards (cont. ) Developed countries – highly industrialized countries with high average per capita GDP –E. g. US, Canada, Japan, Australia, New Zealand, and countries of Europe Developing countries – low to moderately industrialized countries with low to moderate per capita GNP –E. g. China, India, Iran, Iraq, Laos, Peru, Afghanistan ~97% of projected increase in population is expected to take place in developing countries Trade-offs of Economic Development What Is Globalization? Being Connected We live in a world that is increasingly interconnected through economic, cultural, and environmental interdependence Globalization – the process of social, economic, and environmental global changes that lead to an increasingly interconnected world Involves increasing exchanges of people, products, services, capital, and ideas across international borders Factors accelerating it: technology (e. g. internet), human mobility, and international trade and investment Society has become a democratization of learning and communication that has never been seen before it’s so crazy Resources 1-3 What Is a Resource? Things We Need or Want We obtain resources from the environment to meet our needs and wants Resource – anything obtained from the environment to meet our needs and wants (e. g. ood, water, shelter, transportation, recreation) Material resources gotten from the environment is classified as perpetual, renewable, or nonrenewable What Are Perpetual and Renewable Resources? Resources That Can Last Resources renewed by natural processes are sustainable if we do not use them faster than they are replenished Perpetual resource – resource that is renewed continuously (e. g. solar energy) Renewable resource – resource that can be replenished fairly rapidly (e. g. forests) Sustainable yield – the highest rate at which a renewable r esource can be used indefinitely without reducing its available supply Environmental degradation – when a renewable resource’s natural replacement rate is exceeded, shrinking the available supply (e. g. eforestation) Case Study: The Tragedy of the Commons- Degrading Free Renewable Resources Renewable resources that are freely available to everyone can be degraded Common-property / free-access resources – overused and causes environmental degradation (e. g. clean air, public land) Tragedy of the commons – degradation of renewable free-access resources, coined by Garrett Hardin in 1968 –â€Å"If I do not use this resource, someone else will. The little bit I use or pollute is not enough to matter, and such resources are renewable†¦Ã¢â‚¬  Solution: use free-access resources at rates well below their sustainable yields, by regulating them or reducing population Not as good solution: convert free-access resources to private ownership. However, they may not always protect their resources and is not practical for global common resources What Is Our Ecological Footprint? Our Growing Environmental Impact Supplying each person with renewable resources and absorbing the wastes from such resource use creates a large ecological footprint or environmental impact Per capita ecological footprint – amount of biologically productive land and water needed to supply each person or population with the renewable resources they use and to absorb or dispose of the wastes from such resource use Currently, humanity’s footprint exceeds the earth’s biological capacity to renew resources by 15% What Are Nonrenewable Resources? Resources We Can Deplete Nonrenewable resources can be economically depleted to the point where it costs too much to obtain what is left Nonrenewable resources – resources that exist in a fixed quantity or stock, can be renewed in maybe a few hundreds or thousands of years –Energy resources (coal, oil, and natural gas that cannot be recycled) –Metallic mineral resources (iron, copper, aluminum that can be recycled) –Nonmetallic mineral resources (salt, clay, sand, and phosphates which are difficult to recycle) We never complete exhaust a resource, it becomes economically depleted when it costs more to extract it than it’s economical value We can either try to find more, recycle or reuse existing supplies (not nonrenewable energy resources), waste less, use less, develop substitute, or wait millions of years (GOOD IDEA. ) What Are Nonrenewable Resources? Resources We Can Deplete (cont. ) Recycling – collecting waste materials, processing them into new materials, and selling the new products Reuse – using a resource again in the same form Recycling nonrenewable metallic resources takes much less energy and resources than using virgin metallic resources pollution 1-4 Where Do Pollutants Come From, and What Are Their Harmful Ef fects? Threats to Health and Survival Pollutants are chemicals found at high enough levels in the environment to cause harm to people or other organisms Pollution – presence of substances at high enough levels in air, water, soil, or food to threaten the health, survival, or activities of humans or other organisms Most pollution is anthropogenic, near urban and industrial areas Industrialized agriculture is also a major source of pollution Point sources – single, identifiable sources of pollution Nonpoint sources – dispersed and often difficult to identify Three types of unwanted effects –Disrupt or degrade life-support systems for humans and other species –Damage wildlife, human health, and property –Can be nuisances such as noise and unpleasant smells, tastes, and sights Solutions: What Can We Do about Pollution? Prevention Pays We can try to clean up pollutants in the environment or prevent them from entering the environment Pollution prevention / input pollution control – reduces or eliminates the production of pollutants, more effective Pollution cleanup / output pollution control – cleaning up or diluting pollutants after they were processed Problems with pollution cleanup –Only temporary –Remove one pollutant? You get another pollutant –Too expensive to reduce to acceptable levels Environmental and resource problems: causes and connections 1-5 What Are Key Environmental Problems and Their Basic Causes? The Big Five The big five: –Rapid population growth –Unsustainable resource use –Poverty Not including the environmental costs of economic goods and services in their market prices (poor environmental accounting) –Trying to manage and simplify nature with too little knowledge about how it works (ecological ignorance) What Is the Relationship between Poverty and Environmental Problems? Being Poor Is Bad for People and the Earth Poverty is a major threat to huma n health and the environment They deplete and degrade land for survival They live in places with high levels of air and water pollution and with a great risk of natural disasters More poverty also means more population growth (more children = more economic security) Premature deaths –Malnutrition –Increased susceptibility to normally nonfatal infectious diseases –Lack of access to clean drinking water –Severe respiratory disease and inhaling indoor air pollutants What Is the Relationship between Resource Consumption and Environmental Problems? Affluenza Many consumers in developed countries have become addicted to buying more and more stuff in their search for fulfillment and happiness Affluenza – term used to describe the unsustainable addiction to overconsumption and materialism exhibited in the lifestyles of affluent consumers in the US and other developed countries Admit your problem, go on a stuff diet –Law of progressive simplification: â€Å"True growth occurs as civilizations transfer an increasing proportion of energy and attention from the material side of life to the nonmaterial side and thereby develop their culture, capacity for compassion, sense of community, and strength of democracy† How Can Affluence Help Increase Environmental Quality? Another Side of the Story Affluent countries have more money for improving environmental quality yup How Are Environmental Problems and Their Causes Connected? Exploring Connections Environmental quality is affected by interactions between population size, resource consumption, and technology In developing countries, population size and degradation of resources are key factors to the environmental impact, low per capita resource use In developed countries, high per capita resource use and high levels of pollution and environmental degradation per person usually are the key factors determining overall environmental impact and a country’s ecological footprint per person Is our present course sustainable? 1-6 Are Things Getting Better or Worse? The Answer is Both There is good and bad environmental news Technological optimists overstate the situation because technological innovations and conventional economic growth and development will lead to a wonderful world Environmental pessimists overstate the problems to the point where our environmental situation seems hopeless How Should We Live? A Clash of Environmental Worldviews The way we view the seriousness of environmental problems and how to solve them depends on our environmental worldview Environmental worldview – how you think the world works, what you think your role in the world should be, and what you believe is right and wrong environmental behavior (environmental ethics) Planetary Management Worldview As the planet’s most important species, we are in charge of nature We will not run out of resources because of our ability to develop and find new ones The potential for global economic growth is essentially unlimited Our success depends on how well we manage the earth’s life-support systems, mostly for our own benefit Stewardship Worldview We are the planet’s most important species but we have an ethical responsibility to care for the rest of nature We will probably not run out of resources but they should not be wasted We should encourage environmentally beneficial forms of economic growth and discourage environmentally harmful forms of economic growth Our success depends on how well we can manage the earth’s life-support systems for our benefit and for the rest of nature Environmental Wisdom Worldview Nature exists for all species, not just for us and we are not in charge of the earth The earth’s resources are limited, should not be wasted, and are not all for us We should encourage earth-sustaining forms of economic growth and discourage earth-degrading forms Our success depends on learning how the earth sustains itself and integrating such lessons from nature (environmental wisdom) into the ways we think and act What Are the Greatest Environmental Problems We Face Now and in the Future? The Big Picture Poverty and malnutrition, smoking, infectious diseases, water shortages, biodiversity loss, and climate changes are the most serious environmental problems we face What Is Environmentally Sustainable Economic Development? Rewarding Environmentally Beneficial Activities Environmentally sustainable economic development rewards environmentally beneficial and sustainable activities and discourages environmentally harmful and unsustainable activities Environmentally sustainable economic development – uses economic rewards to encourage environmentally beneficial and more sustainable forms of economic growth and economic penalties to discourage environmentally harmful and unsustainable forms of economic growth

Biography of Jean Baptiste Lamarck

Biography of Jean Baptiste Lamarck Early Life and Education Jean-Baptiste Lamarck was born in Northern France on August 1, 1744. He was the youngest of eleven children born to Philippe Jacques de Monet de La Marck and Marie-Franà §oise de Fontaines de Chuignolles, a noble but not rich family. Most men in Lamarcks family went into the military, including his father and older brothers. However, Jeans father pushed him toward a career in the Church, so Lamarck went to a Jesuit college in the late 1750s. When his father died in 1760, Lamarck rode off to a battle in Germany and joined the French army. He quickly rose through the military ranks and became a commanding Lieutenant over troops stationed in Monaco. Unfortunately, Lamarck was injured during a game he was playing with his troops and after surgery made the injury worse, he was decommissioned. He then went off to study medicine with his brother, but decided along the way that the natural world, and particularly botany, were a better choice for him. Biography In 1778 he published Flore franà §aise, a book that contained the first dichotomous key that helped identify different species based on contrasting characteristics. His work earned him the title of Botanist to the King which was given to him by Comte de Buffon in 1781. He was able to then travel around Europe and collect plant samples and data for his work. Turning his attention to the animal kingdom, Lamarck was the first to use the term invertebrate to describe animals without backbones. He began collecting fossils and studying all sorts of simple species. Unfortunately, he became completely blind before he finished his writings on the subject, but he was assisted by his daughter so he could publish his works on zoology. His most well-known contributions to zoology were rooted in the Theory of Evolution. Lamarck was the first to claim that humans had evolved from a lower species. In fact, his hypothesis stated that all living things built up from the most simple all the way up to humans. He believed that new species spontaneously generated and body parts or organs that were not used would just shrivel up and go away. His contemporary, Georges Cuvier, quickly denounced this idea and worked hard to promote his own nearly opposite ideas. Jean-Baptiste Lamarck was one of the first scientists to publish the idea that adaptation occurred in species to help them better survive in the environment. He went on to assert that these physical changes were then passed down to the next generation. While this is now known to be incorrect, Charles Darwin used these ideas when forming his theory of Natural Selection. Personal Life Jean-Baptiste Lamarck had a total of eight children with three different wives. His first wife, Marie Rosalie Delaporte, gave him six children before she died in 1792. However, they did not marry until she was on her deathbed. His second wife, Charlotte Victoire Reverdy gave birth to two children but died two years after they were married. His final wife, Julie Mallet, did not have any children before she died in 1819. It is rumored that Lamarck may have had a fourth wife, but it has not been confirmed. However, it is clear that he had one deaf son and another son who was declared clinically insane. His two living daughters took care of him on his deathbed and were left poor. Only one living son was making a good living as an engineer and had children at the time of Lamarcks death.

Article on the reflection of media on new scientific research Essay

Article on the reflection of media on new scientific research - Essay Example Rossi brings about an understanding that previously used techniques firstly are extremely inefficient and do not always produce a true IPS. Secondly, due to the use of a retroviral vectors the cells tend to reject the attempt of incorporating the modified RNA and view the viruses as infectious threat leading them to undergo apoptosis and activation of interferon pathways. Furthermore, due to the nature of retroviral integration the cells become prone to mutagenesis leading to cancer due to activation of Onco-genes. Thirdly, once an IPS cell is produced by the old method there is a question of how closely these cells are able to act as the Gold Standard ES Embryonic Stem cells, and if they are prone to reversing back to their pre- induced state. Lastly, the future of IPS is to have them generated specifically for each patient and the old ways of Pluripotency Induction are very limited and only a small amount of Pluripotent cells are able to be derived (Johnson, 2010). New IPS cell der ivation technique is quite impressive in a number of ways; primarily in the derivation simplicity and then in the technique itself. Above all Rossi states there is no need for a specialized lab, as any scientist with basic RNA modifying equipment is able to create the IPS cells, the media realizes this opens up enumerate possibilities for not only future research but also gene therapy(Warren et al., 2010). These therapies will be able tobe carried out all over the world as regular scientist will be able to modify cells in not only high tech labs such as Harvard Univerity but also in remote places as hospitals across Africa. The IPS generation technique described in the Rossi article entitled â€Å"Highly Efficient Reprogramming to Pluripotency and Directed Differentiation of Human Cells with Synthetic Modified mRNA† discusses that the induction discovered by Yamanaka requires the manipulation of only four Genes; KLF4, c-MYC, OCT4, and SOX2 (KMOS) are the four strips of RNA th at are required as transcription factors to re-set a skin cell in to an IPS cell. As it turns out the new induction procedure is also faster at producing IPS cells; Lowry and Takahashi found that the new technique produces IPS cells with efficiency thirty six times the previously used method, this indicates an enumerate improvement on IPS cell production efficiency, and opens opportunities for larger scale treatments in the future. As the comparative research carried out by Chan and Lowry indicates the new technique produces IPS colonies within seventeen days, which is roughly twice as fast then the four week minimum it would take using the out dated technique. Over all, the media reporters seem to be moving in the direction of how this research will effect the general population, clinical stem cell application and future research. Their curiosity is in the right place as this research will revolutionize the way stem cells are perceived by the general public, since we probably will no longer require cells from aborted fetuses. Moreover, due to the quantity and speed of production of IPS cells researchers may conduct mass scale clinical

Fate of Freewill Essay Example | Topics and Well Written Essays - 500 words

Fate of Freewill - Essay Example The text explores a variety of themes, including fate vs. free will, as well as religious concerns related to Anglo-Saxon belief and Christian ideology. This essay examines these themes and argues that they demonstrate Beowulf is a text that embraces free will most firmly. Fate and free both play prominent roles in Beowulf. Ostensibly, the poem embraces the notion of fate. In these regards, the poet indicates that God controls the characters’ actions. The poem states, â€Å"Fate goes ever as fate must† (31). This statement refers to the notion of fate as dictating the lives and actions of the main characters. While the epic poem ostensibly embraces fate, in other instances, it seems to adopt an epistemological outlook that indicates the characters are responsible for their actions. One considers that the poem states, â€Å"And a young prince must be prudent like that, giving freely while his father lives so that afterwards in age when fighting starts steadfast companions will stand by him and hold the line. Behavior that’s admired is the path to power among people everywhere† (20-25). This statement considers the nature of behavior in warrior society. The emphasis on behavior is a clear embracement of the notion of human fr ee will. Ultimately, both fate and free will are exemplified in the poem. Beowulf also explores Anglo-Saxon and Christian religious ideology. The contrasting position of religious ideology and Anglo-Saxon belief in the story seems to indicate that the text most comprehensively embraces free will. Christian ideology is a prominent part of the text, as God is viewed as overseeing the action in the story. Additionally, the importance of being humble is viewed as deriving from Christian ideology. In this way, Christian ideology is woven into the very fabric of the text. In addition to these elements, however, Anglo-Saxon elements are considered that at times are not

Top 5 Essay Topics and Tips How to Be Original Essay Example for Free

Top 5 Essay Topics and Tips How to Be Original Essay The first writers on Earth were not actually writing – they were drawing pictures of the daily life. That was long before the actual writing started. Those days one did not have to be creative to â€Å"write† – a piece of chalk and a cave wall was more than enough. Luckily, we have evolved, and despite they write, the present Homo sapiens also try to deliver a unique, one-of-a-kind written message to the world. Believe it or not, creativity is very hard to achieve, and now you will find out why and what do with it. It seems like all the imaginable and unimaginable issues have been already discussed, described and published. So contributing a breath of fresh air to the endless stream of mass media looks impossible. Not only professional writers and journalists face the problem with being creative and original, but the students as well. Writing an essay, a term paper or a research paper can sometimes be compared to childbirth – with sweat and blood, a painful process that drives you crazy. That is why more and more students avoid all these troubles and turn to professional writing services for help. It is a great idea, though it will never make one original. Don’t be desperate – there are a few ways to keep your creativeness up. First of all – cheer up, buddy! It’s a simple psychological factor – the more negative thoughts you have in your head, the less creative and productive you are. Just smile, take your laptop/sheet of paper/notebook and start writing. Some instructors are likely to give you a topic. It makes your task much easier, as at least you know what to write about. But if you picked up a creative writing course – forget about it, most of the times you will be the one to come up with an interesting point to dwell on. At the stage of choosing the headline for your essay, the Internet or any published media can be of a great help. Try searching for the information you are interested in, what fascinates you most. This will keep up and feed your motivation, which is a vital thing for creativeness. Once you sifted through all the materials you found and came up with a topic you want to write on, you are ready to move further. Concentrate on your topic and write down your ideas – simply put your thoughts on the paper (thoughts like â€Å"I wanna eat† or â€Å"It was a great party last night† do not count!). Avoid going off-topic. Please note that in order to write something worthy and interesting, you are supposed and advised to spend at least 2-3 days on the writing process. Here I explain why: after you reviewed the articles on your chosen topic, your brain is overwhelmed with information, and to dot one’s is and cross one’s ts you need some rest. It’s better to make a research in the evening and start writing in the morning, with all the material in your hands. Fresh and creative ideas will fill your imagination for sure! If the very first stage has caused you troubles, you can use the following top 5 essay topics: Can love be associated with pain? Role models in your life Smoking – a bad habit or a disease? How to fight a depression? Pros and cons of having a pet I would like to sum up with a famous quote from Steve Jobs: â€Å"Stay hungry, stay foolish†. This phrase is the key to creativity. Dear reader, strive for knowledge, education and explore the world – nothing else will make you truly original.

Physics and Computer Games :: Physics Computers Science Video Games

Computer games have steadily become a form of mainstream entertainment ever since Pong was released back in 1958. Today, it is hard to find an electronics department in any store that doesn't carry some sort of computer game. "Big deal," you say, "Everyone knows about computer games. What does they have to do with physics?" Well, the technology for creating more powerful software is constantly advancing, and since games are a form of software, they too become more and more advanced. As games become more advanced, game developers aim to create games that offer a more realistic experience. The technology has advanced to such a stage that making the games look real is no problem, but making a truly immersive experience is something different. That's where physics comes in. Well, to answer that, you have to have a basic understanding of physics. Physics is the study of matter and energy, and how the two interact with each other. Things such as gravity, sound and light - all involve physics. As you might have noticed, gravity, sound and light are things we encounter quite frequently in our day to day routines. Game developers, in their goal to create a believable, realistic world for the gamer to immerse themselves in, know that in order to do so their game needs to incorporate the laws of physics. After all, their games wouldn't be very realistic if players kept floating away every time they tried to make their character jump or dodge around. Gravity is only a small part of the realism experience. Developers have to incorporate as many laws of physics as they can in order to make their game truly realistic. Collisions play a big part in any game - it wouldn't be very believeable to allow players to move through walls or objects. Some games take the collision and elasticity elements further, and create extremely elaborate physics engines that can handle, say, two cars colliding, and produce a believeable outcome to the collision. Games like F1 Championship Racing and GTA3 have excellent physics engines that feature some really impressive automobile simulations. Many old games simply use gravity and collision detection in their games, but more recent games involve much more complicated physics applications. So How Do They Do It? Game developers use physics engines to simulate the physics effects in their games. What's a physics engine? A physics engine is a specialized piece of software specifically designed to integrate the laws of physics into a game.

Pompeys Wives

Pompey's Wives Pompey the Great appears to have been a faithful and passionate husband. His marriages, however, were probably made for political convenience. In his longest lasting marriage, he sired three children. Two of his other marriages ended when Pompeys wives died in childbirth. The final marriage ended when Pompey himself was killed. Antistia Antistia was the daughter of a praetor named Antistius whom Pompey impressed when he defended himself before the praetor against a charge of possession of stolen property in 86 B.C. The praetor offered Pompey his daughter in marriage. Pompey accepted. Later, Antistias father was killed because of his connection with Pompey; in her grief, Antistias mother committed suicide. Aemilia In 82 B.C., Sulla persuaded Pompey to divorce Antistia in order to remarry his stepdaughter, Aemilia. At the time, Aemilia was pregnant by her husband, M. Acilius Glabrio. She was reluctant to marry Pompey but did so anyway and soon died in childbirth. Mucia Q. Mucius Scaevola was the father of Pompeys 3rd wife, Mucia, whom he married in 79 B.C. Their marriage lasted until 62 B.C., during which time they had a daughter, Pompeia, and two sons, Gnaeus and Sextus. Pompey eventually divorced Mucia. Asconius, Plutarch, and Suetonius say Mucia was unfaithful with Suetonius alone specifying the paramour as Caesar. However, it isnt clear why exactly Pompey divorced Mucia. Julia In 59 B.C. Pompey married the much younger daughter of Caesar, Julia, who was already engaged to Q. Servilius Caepio. Caepio was unhappy so Pompey offered him his own daughter Pompeia. Julia miscarried a few days after she had fainted in shock at seeing blood-stained clothing that made her fear her husband had been killed. In 54 B.C., Julia was pregnant again. She died in childbirth as she gave birth to a daughter who lasted only a few days. Cornelia Pompeys fifth wife was Cornelia, daughter of Metellus Scipio and widow of Publius Crassus. She was young enough to have been married to his sons, but the marriage appears to have been a loving one like the one with Julia. During the civil war, Cornelia stayed on Lesbos. Pompey joined her there and from there they went to Egypt where Pompey was killed. Source:The Five Wives of Pompey the Great, by Shelley P. Haley. Greece Rome, 2nd Ser., Vol. 32, No. 1.

Write your own editorial - Assignment Example This unfortunate situation can be exacerbated even more by the fact that some teachers feel they must punish students who arrive even a minute or two late with a detention, giving students a sense of stress, anxiety and urgency, and encouraging them to do whatever they can to make it to class on time, even if it means being rude or behaving dangerously towards fellow students or themselves, by, for instance, running in hallways or down staircases. Luckily, however, there are some solutions to this problem. By far the simplest is to simply change it back to the old system where students were allowed four minutes to get between classes. This represents an increase of thirty-three percent of time between classes, and would give students all the time they need. The downside is that this would make some classes longer than others, but only by a minute, and most classes tend not to use exactly the amount of time allotted anyways. Another solution is to allow students a grace period of one or two minutes after classes start where they will not be given detentions for lateness – this will mean students will still have to rush to classes but will be more judicious knowing that serious consequences will not result from minor tardiness. The bottom line is the current system does not work, and must be
