...Should the world use biofuels? In our rapidly changing world we have petroleum fuel that gives life to our whole society. We have two main options for fuel. On one hand, we have fossil fuels, which causes a great deal of pollution our planet and although we have plenty of fuel reserves now, this fuel is not renewable and will therefore be exhausted in the future. On the other hand，we have biofuels, renewable fuel that do not cause as much pollution; however, biofuels would require research, development and other changes in the established system. Biofuels would be a good alternative to fossil fuels, but require research and development. One reason biofuels should be used is that they are made from renewable plant material. Two examples of good possible sources of biofuel are kudzu and algae both of which can grow very quickly and are not used for the food of the human population. These two plants yield a great deal of renewable fuel that can replace the fossil fuels in use today. The ability to produce renewable fuel is an important faction into the why the world should use of biofuel as opposed to fossil fuel. The second reason that the world should use biofuel as opposed to fossil fuel is that they produce much less pollution in comparison to their fossil fuels counterparts. Fossil fuels release gases that have been formally trapped in the Earths crust; therefore, they cause much more pollution then biofuels, which do not release formally trapped gases but gases that were...

...Ashford University Early Childhood Classroom 203 Instructor: Chandra Farmer An overview to what the children will be learning Understanding of Early Learning Standards: Lesson Plans Developmentally Appropriate Practices Play and Socialization Assessment Strategies References. Early Learning Standards It is important for parents to understand why Early Learning Standards are implemented in the classroom. There are many benefits of identified Early Learning Standards. The purpose of these standards is to prepare children to enter into kindergarten. It provides them with a head start on how to solve problems, get in a daily routine, and become more aware to how school works. It is very beneficial to have guidelines in place in order for educators to know what type of curriculum to teach. It can really “contribute to school readiness” (Gronlund, p. 4, 2006). It can help the children make an easier transition into kindergarten and help their communication levels (Gronlund, p. 4, 2006). Throughout my class every subject will follow the guidelines for the Early Learning Standards. I will let the parents always be aware of what those standards are for each subject. How I will communicate the standards, “Philosophy, mission’s statements, parent orientation materials, handouts, newsletters, and announcements. Here are a few example how I can communicate to the parents about what is going on in the classroom (Gronlund, p.134, 2006). . Sending home weekly progress...

...An Evolutionary Fork: Fossil Record Evidence of Humanity and Its Variation From the Primate The early history of humans (homo-sapiens) is a contentious and heavily debated subject in the scientific community. Exactly when and from which ancestry our species evolved is a topic of speculation that many disagree on. What most in the scientific community can almost unanimously agree on is that homo-sapiens did indeed evolve from lesser beings. There is no shortage of fossil record indicating evolution as a force in this world’s early progression. The real debate begins with when humans arrived in the fossil record themselves. The function of this essay will be to first designate which characteristics define and distinguish humans from other animals and in particular other primates. Second it will serve to discuss the earliest fossil records of humanity and their significance scientifically. These conclusions will seek to provide a viable definition for the above posed question of the evolutionary root of homo-sapiens. In order to determine when humans first began showing up in fossil records one must assign humans recognizable and unique characteristics that can distinguish them from other primates that may have been similar in appearance and structure to homo-sapiens’ early ancestors. Prior to that designation though, one must ascertain why the distinction must be made at all. Why must a clear distinction be made from other primates and not from early reptiles or other...

...Writing Assignment #3 Many people believe that fossils can be found about anywhere in the world, but there are certain locations where they can be located. Charles Darwin proposed that humans probably arose in Africa, and was explained thoughtfully in his book The Descent of Man and Selection in Relation to Sex. He believed that Africa was the most likely place to find fossils because our “early progenitors” lived on the African continent (pg. 90). Apes adopted the tropical climate, and he believed that humans were more alike with African apes, than Asian apes. As it came to happen, some of the biggest discovers would be found in Africa. With new discovers, it is quite intriguing to come upon something new, that perhaps the world has never seen before. Owen Lovejoy helped discover why Ardipithecus ramidus is so unusual, which represents the transition from tree dwelling to ground dwelling. He had lots of evidence to prove that this new structure was seen in Ardi, which was a new body plan. He discovered that Ardi’s hands fit together in a way that allowed the hand to bend far backward at the wrist, If lovejoy is right, this means that Ardi never went through a knuckle-walking stage like experts believed she did(pg. 92). He also pointed that Ardi’s pelvic blades, were shorter and broader than apes, which would let her balance on one leg while walking upright. Lovejoy also claims that she had an opposable big toe, which meant she was able to grasp branches, suggesting she spent...

...------------------------------------------------- Design Technology ------------------------------------------------- Research Essay Chitransh Mathur Task: Research Essay Unit: Systems Design Due Date: 29/4/13 Weighting: 25% The concept of renewable energy within Australia, particularly Solar Energy has a huge scope of serious development and benefit to our future energy needs. Our country to this date has the highest average solar radiation per square meter of any country in the world (Geoscience Australia, 2012). Even our solar radiation in the southern regions has a higher overall radiation than countries like Germany, who are one of the most developed nations in terms of Solar Energy. Since late 2012, 10% of Australian energy relies on renewable sources of which 0.03% is Solar (T. Flannery, V.Sahajwalla, 2012). Although this percentage is small, due to the continual evolution of the concept and the current state of the economy and particularly the feed-in tariffs schemes; Solar Energy in Australia is becoming progressively affordable. The current state of Solar Energy in Australia is advancing, though obstacles such as ecological impacts & risks, the heritage & cultural boundaries placed within Australia...

...Week 1 Critical and Creative Thinking Questions Name: Gardner Chapter 1 3. How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts, huge volcanic eruptions or great earthquakes? Uniformitarianism is a scientific clarification on how the rocks, continents and mountains in the planet are created. The material process that occurs on earth has not changed; although the objective conditions have changed radically the principle of uniformitarianism accounts for the outcome of the catastrophe or natural calamity. 4. In this chapter we have suggested that Earth is a close approximation of a natural closed system, and we have hinted at some of the ways that living in a closed system effects each of us. Can you think of some other ways? Mainly a closed system is a system which is isolated from a larger system or environment. Closed systems, are detained to be isolated from their environment. The effect that changes in a reservoir, like CO2 levels have a close system effect on us. 5. In what ways do geologic process affect your daily life? There are several ways that Geologic Processes affect our lives. By description a geologic process is a normal way of modifying the face of the Earth. With this significance, the processes such as withering, desertification, stratification, soil erosion,and alluvion. These processes can sometimes take form in natural disasters such as Tsunami and...

...discoveries of fossil hominins (members of the human lineage) led to important insights into human evolution. He was raised on a dairy farm near Laidley, attended Toowong and Blenheim state and Ipswich Grammar schools. He graduated from the University of Queensland with first-class honours in biology, and studied medicine at University of Sydney. He acted vice-principal of St. Andrew’s College in 1917. He was a medical officer at Royal Prince Alfred Hospital, and as a captain in the Australian Army Medical Corps, served in England and France. In England, Dart took a post at University College, London, as senior demonstrator in anatomy. Then, he spent a year on Rockefeller Foundation fellowship in USA. He married to Dora Tyree, an instructor in anatomy, in 1921. In January 1923, he moved to South Africa, as a professor of anatomy at The University of the Witwatersrand, Johannesburg. In November 1924 Dart was given a fossil skull that had been found recently at Taungs. He extracted the fossil from the hard matrix and found that the skull was a child’s. It was a mixture of apish and human features. Its teeth were human-like while its brain was the size of an ape’s. Raymond Dart had found the missing link in the man-ape line of evolution. He died on 22nd November 1988 at the age of 95 in Reno, Nevada. I am interested in Raymond Dart’s work because it is fascinating to see what a unique species we are, and how we have evolved into what we are today. I also think it is important to understand...

...My Reflection on Why Evolution is True by Jerry Coyne The textbook Why Evolution is True was an extremely easy read with lots of whimsical thoughts thrown in to keep you attentive. My decision to take an evolution class as an elective was one that I had to truly take some thought and time to finally enroll. While my religious ties are very deep, I needed to open my mind to the possibility of different explanations into the creation of the creatures that inhabit the earth. My fears and tension were calmed when I read the preface to the book Mr. Coyne stated it so well and to the point: Accepting evolution needn’t turn you into a despairing nihilist or rob your life of purpose and meaning. It won’t make you immoral or give you the sentiments of a Stalin or Hitler. Nor need it promote atheism, for enlightened religion has always found a way to accommodate the advances of science. In fact, understanding evolution should surely deepen and enrich our appreciation of the living world and our place in it. (Coyne, 2009, p. xx) With this introduction to the text and Mr. Coyne’s calming of my fears that I would not burn in hell or be betraying my religion by opening my mind and heart to the information that is being provided. Why not open my mind to the possibility that the Theory of Evolution has some truth that is proven by scientific facts, I believe in medicine and that is based on scientific facts and research. The journey through each of the chapters covered in, Is Evolution...

...Waste and Energy Paper Name ENV 100 April 11, 2011 Tamue L. Gibson, M.S. Waste and Energy Paper Pollution introduces contaminants or pollutants into the natural environment that causes unsteadiness and long-term effects to the ecosystem. Waste is slowly polluting the environment and killing humans, plant life, and animals. Waste comes in many forms: solid waste; plastic, hazardous waste material; nuclear waste, and fossil fuel; oil. The world has become a gigantic trashcan. With the expansion of technology, humans are gutting out the earth’s resources, the results are creating an imbalance in the climate, and millions are suffering from ill health. Biological diversity in parts of the world has become an important issue of discussion to environmental activist. Recommendations for illuminating waste are concerns of nations worldwide. Alternative solutions will make way for improvement to the environment and health for millions of people. Plastic bottles are washing ashore on beaches and polluting the oceans. Plastic bottles are the largest source of pollution (Plastic Pollution Collation, 2010). Such items as plastic utensils, straws, lids, and bottles are releasing chemicals into the ocean and destroying the marine life beneath. Although designed for temporary use, they remain around forever. The American Chemical Society studied water samples and found polystyrene, a commonly used plastic found in cutlery and Styrofoam, and went on to say that plastic is a new source...

...of this can be solar energy. We take the energy from the sun and change it into usable energy for our homes, businesses, schools, and hospitals. This law also applies to energy conservation in that some energy is always wasted when being changed from one form into another. It is impossible to change energy without actually wasting some of it. In many energy conversions, more energy is wasted that is used for work such as automobile engines, they typically waste more than two-thirds of the total energy used, primarily through heat (Law of Conservation, n.d.). Fossil fuels such as oil, natural gas, and coal were formed many hundreds of millions of years ago before the time of dinosaurs, hence the name fossil fuels (Where Fossil Fuels Come From , 2012). Coal actually provides one-fourth of the world’s commercial energy consumption and when over consumption happens, coal causes air pollution. The burning of fossil fuels emits carbon monoxide,...

Through the extensive use of fossil fuel and other types of activities that harm our environment along with the decreasing availability of energy resources due to over using it. Studies show that the United States for example, relies heavily on fossil fuels and 86% of its total energy demands come from fossil fuel, which the U.S. is considered the world’s largest consumer of energy. In addition, the U.S. imports oil from the Persian Gulf and OPEC and that will not last forever because oil is scarce, therefore, alternative energy sources should be considered such as renewable energy to satisfy the high demand of energy that we have nowadays (Asif and Muneer, 2007)....

...implication. Definition of the Problem It is not an easy task to define environmental problem. The issue is too complex and broad to summarize it in several sentences. Some people believe that environmental policy refers only to human relationships to nature; they understand that much environmental policy deals with human health concerns (Kraft & Furlong, 2009, p.341). Putting environmental policy even at a broader context, it can be defined as government actions that affect environmental quality and the use of natural resources (Kraft & Furlong, 2009, p.342). There is no doubt that environmental issues are global issues. Entire world is facing important environmental problems that need to be addressed at both state level and collaborative international level. United States alone is “the largest single emitter of carbon dioxide from the burning of fossil fuels” (www.cia.gov). Besides that air pollution in the United States resulting in acid rains; water pollution from runoff of pesticides and...

These changes can occur over billions of years and go unnoticed in short periods, but are significantly different in a lengthy time period. Discuss what a physical anthropologist may examine/investigate in order to study evolution (e.g. population DNA). One aspect of physical anthropology that examines and investigates the process of evolution would be Paleoanthropology. Paleoanthropologists are individuals who study extinct organisms or fossils. It’s important to understand that they are not searching for human ancestors but rather our biological and technological origins and evolution. (Middle Awash Project UC Berkley, 2015). There are several important aspects that are studied, such as reproduction, anatomy, and physiology of these individuals.

...Frank Marchese GBLW 435 08 Sept. 2013 GBLW 435 Paper #1 Science to me is the study of our world through on-going experiments and cases. It is a very important topic because through it we are able to understand the environment we live in and how we affect the world. Scientist spend their lives searching for answers so we can better understand the impact we have on the environment and try to find better ways of accomplishing the tasks we face in everyday life. Everything in our world is interrelated, the fossil fuels and other materials that we use every day have a huge effect on the world’s environment. Coal has been used for heating since cavemen were living on the earth. Archeologists have also found evidence that the Romans in England used it in the second and third centuries. Coal, along with other fossil fuels, have been used as a source of energy and have had an effect on our environment. The average amount of carbon dioxide produced per year is 21.3 billion tonnes and our environment can only displace half of that amount, which leads to the pollution of our atmosphere. If the human race continues on its use of heavy fossil fuels the global warming crisis will only become worse along with our living conditions. The process which is used in science is called the scientific method. The scientific method starts with making a hypothesis or a theory, then through testing and researching come to a conclusion about the research they have done. Along with testing and...

...the following question: 'Is the Interface model a prototype company for the 21st Century? If so why, if not why not? Prototype companies are vital so industry can move forward with world sustainability in the 21st Century. Interface is the role model of a prototypical company of the 21st Century as they promote and employ elements of Zero Discharge, reduced benign emissions, open communication, efficient transportation and logistics, and renewable energy concepts. Zero Discharge creates an environment in industry where waste and emissions are re-invented through systems of recovery and are reused by either the same plant or other manufactures as a raw material. Reduced benign emissions is process that benefits the community through reduced pollution and also increases profits for a company by waste reduction. Open communication shows a business’s transparency and investment in its stakeholders, by business being open to their operations the stakeholders feel a sense in confidence of a business’ operations. Resource efficient transportation and logistics which looks at aspects of improving air quality, using hybrid vehicles and the careful planning of positioning factories close to their customers, results in more sustainable logistical operations. Renewable Energy, with a strong prominence on photovoltaic cells, creates a long term solution to the rising costs of diminishing fossil fuels. Photovoltaic energy systems use no moving parts and convert solar energy directly into...
