Environmental Science

In the assigned reading for this unit, you learned about various chemicals that induce reproductive toxicity. Not limiting yourself to the chemicals that are mentioned in the assigned reading, identify a toxicant that causes reproductive toxicity. Develop a research paper that includes the following:background information on the toxicant, its use, and routes of exposure;the process by which this toxicant causes reproductive toxicity and the concentration of exposure;ways exposure to the toxicant might be limited, treated, and/or effects reversed; andrecent research findings (within the last five years) on this toxicant.The research paper should be a minimum of three pages in length, not including the title and reference pages, and written in APA format with proper in-text citations and references. The paper should utilize at least three credible sources that include at least one peer reviewed journal article published within the last five years

Question: What are some economic and social benefits of the Slow Food movement? What are some potential economic and social consequences? How has Terra Madre served to address the charge of “elitism” within the Slow Food movement? In which realms might it still make improvements?

general guidelines:Throughout, be sure to answer the questions thoroughly, but only the questions.All answers should be 1 to 2 pages each, typed and double spaced, using 12-point font size.Write only in complete sentences, and useformal English throughout. The quality of your spelling, grammar and English usage is anindicator of the time and effort that you have put into this assignment, and will be reflected inyour grade.Answer FOUR out of the following five questions in paragraph form, 1 to 2 pages each (double space):1.The United States’ efforts to combat air and water pollution began in earnest in the 1960s and early 1970s. In essay form, describe the Donora, PA air-pollution crisis (1948). Briefly identify and describe the Clean Air Act (1970, with later amendments). Using insights from the movie Erin Brockovich (1988, centering on water pollution), describe the complexities facing plaintiffs seeking to win a class-action “toxic tort” lawsuit against polluting corporations. Discuss.2.Toxic waste is an American and worldwide problem. Describe and explain the Love Canal crisis (late 1970s) in Niagara Falls, NY. In so doing, describe the evolution of the narrative surrounding this environmental case from favoring unrestrained economic development to favoring prevention and amelioration of public-health hazards. Discuss.3.The one-time Rocky Flats defense installation near Denver, Colorado has been the focus of recurring episodes of nuclear (radioactive) contamination of air and water. Describe the evolution of narrative from Rocky Flats being a mandatorily secrecy-shrouded the linchpin in US national defense during the Cold War era, to a public-health hazard due to radiation exposure, and the circumstances behind this shift (including the fires of 1957 and 1969). Discuss.4.Snowmobiling in Yellowstone National Park (Wyoming) began in 1963, and has been the focus of conflict between environmentalists on one side, and snowmobiling enthusiasts and pro-business advocates on the other side. Describe this political conflict, focusing on environmentalists’ claims about air and noise pollution and ecosystem disruption, versus pro-business and snowmobiling advocates’ claims about snowmobiling contributing to the local economy (hotels/motels, restaurants, bars, etc.). Discuss.5.Sometimes, environmental crises have taken the form of “commons problems.” In essay form, describe and explain the “tragedy of the commons” phenomenon first described by Garrett Hardin (1968). Next, describe and explain the New England fisheries crisis (the 1990s to today), including how it represents a commons problem. Comment on the “Ludwig’s ratchet” model that has been argued to propel the New England fisheries crisis across approximately the past 25 years. Discuss

go to these weblinks and learn about ecosystem services, and also learn about the economic value of protecting natural ecosystems and their services.The Ecological Society of AmericaCostanza, R., et. al. (1997). The value of the world’s ecosystem services and natural capital. Nature, 387, 253-260.The United Nations: The Millennium Ecosystem Assessment & HumansOf the different kinds of ecosystem services you learned about, discuss two that are important in your local area, village, forests and/or nation.How are these services endangered and what economic costs to society do you foresee with their loss?For example, when people built homes and buildings over wetlands in Florida, then the wetlands were destroyed. Normally, wetlands are important to help control flooding, and without them, there were more floods and water damage in cities, which caused a lot of economic costs to the citizens. So, now Florida is trying to restore many lost wetlands in order to have the ecosystem service of flood control returned.What is one action that people could take to help protect these services?

This unit has focused on pollution prevention (P2) strategies and best available technologies for the petroleum, transportation, and nanotechnology industries. For this assignment, write an essay that summarizes P2 through the use of best available technologies for one or more of the following industries:petroleum,transportation, ornanotechnology.In addition to your textbook, you must utilize at least one peer-reviewed article from the CSU Online Library. In your paper, limit the number of direct quotations from references. The vast majority of your paper should contain paraphrased information from your sources and should include your own thoughts on source reduction and recycling.Your essay should be at least two full pages in length. A title page and references page must be included; however, these pages will not count toward meeting the minimum page requirement. Adhere to APA Style when constructing this assignment, including in-text citations and references for all sources that are used. Please note that no abstract is needed

Metals are basic elements that do not degrade any further, so they are able to persist in the environment. Metals may not always stay in the same form because they are able to react to form different compounds. Research a metal that was discussed in the textbook reading such as mercury, arsenic, or cadmium. Create a PowerPoint presentation at least seven slides in length, discussing the following:background information on the metal,the cornerstone xenobiotic pharmacokinetic properties and effects of the metal,the bioaccumulative effects of the metal in the environment and how it affects humans and the environment, andconcentration of metal that is considered toxic and symptoms of toxicity by this metal.Your PowerPoint should be a cumulation of what you have learned throughout the course. For instance, if the metal has particular effects on a certain body system or organ, be sure to give information about these effects. The assignment should meet the following requirements:The length should be a minimum of seven slides, not including your title and reference slides.Use speaker notes to explain the key points that are provided in the slides.Include least two visual aids and/or graphics.A minimum of two credible sources should be used for this assignment, and the references should be properly cited in a reference list at the end of the PowerPoin

Before building a new power plant, a utility company must gain permission and procure the required permits for construction from the Environmental Protection Agency (EPA). At this time, the policy of the EPA is to limit construction of power plants to clean burning natural gas systems (to reduce emissions of CO2). One result of this policy is the reluctance of utility companies to build new power plants. California has recently experienced serious problems with their ability to provide enough electricity for its residents because of this reason. One result of this problem is that utility rates in California jumped 500% to 600% in a one-year period.With the above information in mind, write a short essay of at least 1 page discussing pros and cons of this EPA policy. Be sure to keep in mind things like environmental impacts but also issues relating to social impacts due to higher electrical prices. Submit your paper to the appropriate folder in the Dropbox area of the course.

Visit the World Health Organization web site. Look up the current status of Ebola and Leishmaniasis, and compare them to a disease (of your choice) that occurs closer to where you live (consult Figure 8.6 in your text for information).What organisms cause the three diseases? What is their current distribution and prevalence? What environmental (think of natural environment, not their home environment) and social factors (that affect the environment) contribute to their spread? Does any treatment exist for the diseases?
