...Appearance The bald eagle, or Haliaeetus leucocephalus, is a type of bird. Adult bald eagles are distinguishable due to their white head and tails, a contrast to their brown body. Young bald eagles have splotches of white, located on their tails and undersides. They also have a curved, pointed yellow beak. Bald eagles typically reach around one meter (three feet) in height, with a seven foot wingspan. Males weigh between eight and nine pounds, while females weigh ten to fourteen pounds. Location Bald eagles are found throughout North America. Although they live on most of the continent, bald eagles can mainly be found near sources of water such as ponds, lakes, rivers, and streams. It is not uncommon, however, for bald eagles to make their nest in pine forests near the coastline. Diet...

...Mo Yi Lam BISC_102 Professor Kiefer Nov 30th, 2010 Final Paper (Summary of Endangered Species Act) Endangered Species Act “What is an endangered species?” is a question that needs to be addressed before getting known of endangered species act. An endangered species is a population of organisms which is at risk of becoming extinct due to three possible reasons: it is few in numbers. According to the theory of Exponential Growth Curve proposed by Malthus, a lower population tends to have a lower reproductive rate and thus a higher risk of going extinct; or a species is threatened by changing environment. A species which fail to adapt a new environment by means such as mutation which creates new “fitting” genes tends to have a higher risk of going extinct; or it is affected predation parameters. In a community, defined as a group of interacting organisms sharing a populated environment, the population of a species is highly dependent on one another. If the predator population of a species is high, this can limit its reproductive rate and thus the population growth. International Union for Conservation of Nature (IUCN) is an organization which “helps the world find pragmatic solutions to our most pressing environment and development challenges.” (IUCN “About IUCN”)According to one of its reports, the endangered species is 40% of all organisms, which has reached the stage of alarm that endangered species conservation policies must be implemented in no time. ...

...Name: Tutor: Course: College: Date: Animals in Biomedical Research From history, man depends on animals for survival, either as mode of transport or source of food. However, animals are used for many other purposes in the current world. Scientists are using animals for experimenting and testing drugs that prescribed to cure many diseases, for instance, HIV/AIDS. For many years, animals’ experiments have been used to discover new ailments and the drugs that could cure them. However, there are so many organizations that are trying to fight for animal rights by preventing animal experiments. Stopping the use of animals for scientific research can hinder progress in new findings and discoveries in the health sector. Animals have been used for scientific research because their body functions are almost similar to that of human beings. Human suffering should be drastically reduced as a first priority by ensuring that the humans don’t die because simple and treatable diseases. Animal suffering and death should come as a second priority after taking care of humans needs. Scientists should be able to use animals for research to prevent any possible deaths in human beings. Disease like tumors can be experimented and tested on animals and not on man to avoid suffering of human beings. Health of human beings has advanced due research carried out on animals. Major killers like diabetes heart attack and cancer have been treated well due to improved medicine. Some diseases mostly...

...The Search for an Ecology Paper Topic In the search for a paper topic that relates to Ecology, many possibilities emerged, including, of course, the popular Global Warming and Tropical Rainforest topics, but I wanted something different. Soon it was obvious there is confusion as to what Ecology really is. As our text, “Biology: A Guide to the Natural World,” points out, we should assume that many ecologists are environmentalists, but these are two very different professions. Enter “ecology” in the Google search engine, 739,000 topics related to ecology will appear! Clicking on many of these links will direct you to a Website featuring some “environmental” or “conservation” topic, not an “Ecology” topic. Many people assume that ecology and environmental conservation are one in the same and many of the Websites confirm this assumption. Ecology.com combines both ecological and environmental news and articles which only adds to the confusion; one would think a Website with this title would be an “official” Website featuring only factual information; not so, just as many other “official” sounding titles are not “official” websites! In fact, there are many college educated people, my son for example, with this same mind set. The confusion can be blamed on the media hype over the environmental movement. Not many years ago “go green” brought images of tractors, farm equipment, lawn mowers and the words “John Deere,” but today “go green” has a whole new meaning. It seems the word “green...

So it actually a fraud or a human error, the only difference between a fraud and an error is intention. It could be argued that is there any room for scientists to make errors and yes we all are capable of making errors, they can make errors too however they have the chance to correct such errors before publishing such data instead such papers do see the light of the day, a lot is dependent on these scientific researchers then why is the data tampered and results are achieved per the own needs, a research shouldn’t driven as per the needs of an individual or for any sector [1]. It is based on any actual data which may eventually lead to saving lives or aiming for a better world or better resources or a better environment. Driving factors for scientific frauds Science is a result driven discipline, a ‘Publish or Perish ‘environment which is like the survival of the fittest, where everything is data in facts, figures and tables. It could be an increase in competition to stand out, to publish the best journals, research which atleast looks like a breakthrough and the rewards associated with this are also high as compared to the research budgets [2].

...within any population is exceptionally important to the sustainability of any ecosystem or environment. The cycle of life shows us that all species have another species that they rely on for several necessities. Some species use other species for sustenance, some for shelter, or hunting skills. The reasons why species rely on each other vary; however, the need is infinitely important. We will discuss why genetic diversity is so important. We will explain why population management and diversity is necessary to the successful survival of every population. Lastly, we will compare and contrast the ex situ and in situ methods of conservation. It is extremely important for humanity to take responsibility for the failings of some ecosystems and this paper allows us to see the ways that we, as humanity, can help to reverse that damage. Genetic Diversity in Populations Genetic diversity also known as the level of biodiversity simply measures the number of genetic characteristics that the genetic makeup of a particular species consists of. It is different from the term genetic variability as they are many times used alternatively but in reality they are different. So why is genetic diversity so important? It is the basis for the populations of various living species to adapt themselves as the surrounding environment changes. If there is no genetic diversity many of the species will vanish off the face of earth. The environment on the earth changes rapidly and hence with the help of genetic...

...Interpretation is an important component as a means of influencing or even changing environmental attitudes and/or behaviour of visitors to protected areas. The two important components are communicating ideas and enriching visitor experiences. This essay will define interpretation and discuss the effectiveness of interpretation as a means of influencing or even changing environmental attitudes and/or behaviour of visitors to protected areas and evaluate the roles of tourism and environmental agencies in managing & controlling the impacts of tourism in protected areas. For the purpose of this research more visitor-focused definition will be used. Definition of Interpretation There are two ways to describe interpretation. The first would be listing the forms of interpretation. For example: information centre, guide walk and tour, guidebook, brochures and signs or pamphlets that provide information of the protected areas The example given above could be suggested that interpretation incorporates all the various ways in which organizer seek to communicate with their visitors. It is also sometimes refer to as visitors’ education. Recently interpretation has been use as a recognized element of other types of attraction such as theme parks. The increase usage of interpretive activities reflects growing competition between attractions and increasing expectations from visitors. (Harris, 2005) Given the wide range of places where interpretation is used, it is not surprising to...

...Running Head: Environmental Crime Environmental Crime [Name] [School] In partial fulfillment of the requirements for [subject] [Professor] [Date] ABSTRACT Environmental Crime is a very serious crime not only to the present society but also to the next generation of humans, animals and plants. This is a serious matter that affects the whole plant. This research paper discusses the definition of environmental crime, a few examples of companies that had committed environmental crime, environmental laws and crime punishment of the companies who had committed these crimes. Definition of Environmental Crime Environmental Crime is very hard to define. Some people say that it is a white collar crime, to others it is not just simply a white collar crime but it can be considered as crime against society. Whit Gibbons (2001) had shown two types of environmental crime in his article. First type is an individual such as an ordinary person dumping waste to the river and the other type is the white-collared type where companies dump harmful contaminants to a water source or the air. The main difference of the two according to Gibbons (2001) is that it is easier to prosecute an individual than a business corporation. The sad part is the business corporations who commit environmental crimes affects the environment more than an individual. He had treated the business corporation offenders as white-collar criminals and as such defined it...

...INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food. A soil pollutant is any factor which deteriorates the quality, texture and mineral content of the soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse effect on plant growth. The introduction of substances, biological organisms, or energy into the soil, resulting in a change of the soil quality, which is likely to affect the normal use of the soil or endangering public health and the living environment. Soil contaminants are spilled onto the surface through many different activities. Most of these are the result of accidents involving the vehicles that are transporting waste material from site of origin to a disposal site. Soil pollution is particularly dangerous for the environment and our health because soil, either in the mountains or in the plains, contains the largest part of the water we drink and produces all the food we need. There are many types of soil pollution...

...used for Research During the past ten years, a major controversy over the use of animals in biomedical and behavioral research has arisen. The debate about using animals for medical testing has been ongoing for years. The struggle is usually between animal rights activists and scientist. I believe that animal testing is imperative to the progression of medical cures, procedures and drugs. Scientists have been solving medical problems, developing new techniques and treatments, and curing diseases by using animals in biomedical research. Animal rights advocates believe that animals should not be exploited by humans, and that animals have the same rights as humans. Anti-vivisectionists oppose the use of animals in medical research. They believe that medical researchers are cruel and inhumane. Animal Welfare does not oppose all use of animals in research. They oppose inhumane and unnecessary use of animals and fight to eliminate pain and suffering of animals. On the Contrary, scientists argue that animal research is necessary because it helps them develop medications, vaccines, or new procedures to treat or prevent diseases for both humans and animals. Most research projects either do not involve pain or the pain is alleviated with analgesic or anesthetic drugs. They understand that pain causes stress for the animals, and this stress can seriously affect the results of the study. With all these controversies about this issue, why are animals necessary in research? Because...

Rawl, chairman and chief executive of the Exxon Corpoation was in his kitchen sipping coffee when the phone rang and received the news regarding the spilling of crude oil into the frigid waters of Prince William Sound, just outside the harbor of Valdez, Alaska. What was about to happen was the worst environmental disaster in the history of the United States. These were the documented facts that media had portrayed across the United States and to the world: Exxon Valdez, a 978-foot tanker piloted by a captain whom later revealed to be drank, ran aground on a reef 25 miles southwest of the port of Valdez. The results caused a spill of 250,000 barrels, the largest spill ever in North America. The devastating results affects, 1,300 square miles of water, damaging some 600 miles of coastline and murdering as many as 4,000 Alaskan sea otters. The disaster also enshrined the name of Exxon in the all-time Public Relations Hall of Shame. (Seitel, 2000). According to the book, Exxon’s dilemma broke down into five categories. First was the hesitation of Mr. Rawl if he is going directly and personally to Alaska. In an interview Mr. Rawl has said, “We had concluded that there was simply too much for me to coordinate from New York.
