Describe the 4 phases of demographic transition.

You will write a research paper about the demographic transition model and global food production and distribution for a growing human population to meet global food security goals. You must use APA format for the paper and documentation. 3 pages for body, one cover page and one reference page.

Include the following:

  • Describe the demographic transition model and how it was developed by demographers.
  • Describe the 4 phases of demographic transition.
    • For each phase, compare crude birth rates (CBR) to crude death rates (CDR), and state whether the population is stable, growing, or declining in each. ·
  • According to demographers, what factors lead to a decline of the CDR in phase two and the CBR in phase three of the demographic transition? ·
  • Briefly describe 3 living conditions in developed countries that have reached phase four, and contrast them with these same conditions in developing countries that remain in earlier phases.
    • Note: When comparing and contrasting, include details for each of the entities being compared and contrasted. For example, if comparing availability of clean water in a developed country, contrast availability of clean water in a developing country.
  • Research and describe a program for developing countries that would help improve 1 of the 3 conditions that you compared.
  • Food security means that everyone has an adequate amount of nutritious food to lead healthy lives. Research and describe 1 specific program that helps developing countries reach food security goals.

Discuss the prevalence of deforestation and its consequences in the US. Using course materials and web resources, discuss ways in which deforestation is being addressed and offer your opinion of ways efforts may be improved.

The Species Approach to Sustaining Biodiversity

Review the following statements and choose one that best describes your feelings towards wildlife.Defend the statement you choose by providing at least three reasons for your point of view.

  • As long as it stays in its space, wildlife is okay.
  • As long as I do not need its space, wildlife is okay.
  • I have the right to use wildlife habitat to meet my own needs.
  • When you have seen one redwood tree, elephant, or any other form of wildlife, you have seen them all, so lock up a few of each species in a zoo or wildlife park and don not worry about protecting the rest.
  • Wildlife should be protected.

The Ecosystem Approach to Sustaining Biodiversity

The harmful effects of deforestation can reduce biodiversity and the ecological services provided by forests on a global scale. Characteristics of deforestation include acceleration of flooding in surrounding areas, regional climate change from extensive clearing of forested areas, decreased soil fertility from erosion, and premature extinction of species. Discuss the prevalence of deforestation and its consequences in the US. Using course materials and web resources, discuss ways in which deforestation is being addressed and offer your opinion of ways efforts may be improved.

In biological terms, a species is defined as a group of organisms that are able to interbreed to produce fertile and viable offspring under natural conditions. This description of a species can further be characterized as reproductive isolation, where physical and sometimes behavioral traits of an organism will only allow them to reproduce with an organism that has the same traits. Using the aforementioned definition of a species, different breeds of dogs are able to produce fertile and viable offspring because they are all the same species, but dogs and cats are unable to interbreed because they are two different species.

Population

Now, extend the definition of a species to a group of the same species living in the same geographic area. This would represent a population. What would happen if the species within this population were suddenly split into two groups by an earthquake, creating a physical barrier such as a canyon? If a population is divided indefinitely by a barrier, members of the divided population will not have the opportunity to breed with each other.

Impacts

Over many years, the abiotic (nonliving) and biotic (living) conditions on either side of the physical barrier will vary from one another. As a result, natural selection will cause different selective and adaptive pressures to occur between the two divided populations, and they will evolve differently. Over time, this will result in speciation, which is the creation of two new species. This occurs because of reproductive isolation.

  1. Population Growth Population growth, worldwide, is increasing at an alarming rate, at least according to some of the experts in the field. Ultimately, they believe, this will result in depletion of freshwater and forests leading to famine, increased poverty, and so on. What is your view on this issue? Should countries, other than China, enforce population control policies?
  1. Wilderness Areas There is an area of land in northeastern Alaska (19.6 million acres) known as the Arctic National Wildlife Refuge or ANWR. ANWR was created to preserve wildlife and wilderness, but oil has been recovered here since the 1970s. (The area appears to be a repository for a significant amount of crude oil.) What is your opinion about drilling and transporting the oil from this area to the lower states? Is this necessary? What are the effects on the wildlife and the wilderness? What should be done?

For the one you have chosen, do the following:

  • In a page or two, provide a technical summary of the issue, including the science behind the issue. You may use your textbook as the initial source of information, but you must include at least 3 other scientific sources. The sources should be peer-reviewed, scientific journals, not merely sites on the Internet. There are many sources to choose from; for example, Scientific American, Nature, National Geographic, Science, etc. Document your sources correctly in APA style.
  • In addition to your technical summary, prepare a paper of approximately 10 pages (approximately 2500 words). This paper should effectively provide an answer to the question you chose. Include in your paper a critique of the four sources of information you researched. Do you agree or disagree with their position(s) on the topic?

What would be the maximum prison sentence and fines that any individual would face?

Assume that a fatality occurred at your facility one month prior to the OSHA inspection. Review the citations and penalties that were assessed to your facility, and respond to the following questions:   Which of the citations could be referred to the U.S. DOJ for criminal proceedings?  What conditions would have to be met before the citations could be referred for criminal proceedings?  Which individuals working at your facility could face criminal charges under the Act?  What would be the maximum prison sentence and fines that any individual would face?  What would be the maximum fine that the company would face?  If you were facing criminal charges under the Act, what would be your best defense?  How could you involve the OSHRC in the criminal case(s)?  Your response must be a minimum of two pages in length, using at least one reference. All sources must be cited in the text and on the reference page, using APA style. You fail to reach an informal settlement agreement with the area director. You file a Notice to Contest within the required 15-day period. Your case is assigned to an administrative law judge (ALJ). Prepare a document summarizing the case you will submit to the ALJ. The document should discuss the following at a minimum:   which citations and penalties you would contest,  the reasoning behind each contested citation and/or penalty,  documents you would bring to the hearing,  individuals you would use at the hearing,  how the case before the ALJ differs from the informal conference,  what information will be presented before the ALJ that was not presented in the informal conference, and   what information you would request from OSHA as part of discovery.  You must support your actions with reliable sources. Your grade will be based on your ability to present a case to your professor, serving as the ALJ, to reduce or vacate either the severity of some citations or the amount of some penalties. If you simply state that you accept the citations and penalties as written, you will receive a minimal score on the assignment.   Your response must be a minimum of two pages in length, using at least one reference. All sources must be cited in the text and on the reference page, using APA style.
