What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon?

 

Prepare a PowerPoint presentation of 10 slides (not including the Title and Reference slides) and include a minimum of 3 images. Produce a presentation on the following:

 

• Define demographic transition with a brief history of its development.
• Describe the 4 phases of demographic transition, including if the population is stable, growing, or declining in each.
• According to demographers, what factors lead to a decline in the crude birth rates (CBR) and crude death rates (CDR) in the epidemiologic and fertility phases of the demographic transition?
• Briefly describe 3 living conditions or environmental impacts in developed countries that have reached phase IV, and contrast them with these conditions or impacts in developing countries that remain in earlier phases.

Complete the following:

 

• List and describe the food item, and include where it came from (check the label or Web site).
• Use this calculator to determine how far it has traveled to you. Answer the following questions (use the Internet and CTU library to form your opinions):

 

1.      How does the vast movement of food from one nation to another benefit or potentially harm developing nations? Are there benefits of importing food to developed or wealthy nations?

 

2.      There is an “eat local” initiative developing throughout the United States and Europe. What are the benefits to buying fresh, local foods? Are there drawbacks? Do you buy local?

 

3.      Can you live without the food item you chose? Is there a local substitute available?

Write a 1,000- to 1,250-word paper in which you research and identify three prevailing philosophical perspectives at work during the 20th century. Provide an overview of each of the philosophies—where it arose, who created it, and its major tenets.

You have just been elected to head a team within your company that is tasked to rid your manufacturing processes of toxic, hazardous and dangerous chemicals. The company has established a year end goal of being able to claim that the products manufactured at the site are toxic-free and qualify for carrying the new Green Seal Certification on the package and in product literature and advertisements. Senior management believes that this goal will both enhance the reputation of the company and reduce the high costs associated with managing hazardous wastes under the site RCRA Part B permit. Your team has had two unsatisfying meetings and they have yet to arrive at any meaningful approach that will accomplish the goal by the end of the year. Prepare a 250 word essay for each of the three areas below that will serve as a thought starter for the team.

 

• How can alternatives be identified for reducing the use of toxic, hazardous and dangerous chemicals in the manufacturing process. This can include engaging the product development and procurement functions within the company.
• What is the communications strategy that can be deployed that will make key stakeholders (employees, customers, investors, regulators) aware of the project and its intended objectives. Include in your write up the impact that carrying the Green Seal Certification is intended to have in the marketplace.
• Discuss how you expect public purchasing decisions to be influenced when they are given a choice between purchasing higher cost products that are designed for recycle and reuse vs. products that are designed for disposal and are purposefully put on the market at a lower cost.

(45 points total) One way to manage today’s excessive municipal solid waste (MSW) output is to incinerate it. Waste incineration has two benefits: one is that landfills won’t fill and close as quickly, and the other is that burning the waste can produce energy. It is estimated that up to 90% (by volume) of waste can be kept out of landfills by incinerating it. Waste incinerators have been around for a long time, but were phased out in the 1970s due to pollution concerns and other negative effects on the environment. Today’s waste-to-energy facilities are making a comeback and it is due in large part to technological improvements that reduce the amount of pollution.

 

1. (25 points) Describe how waste can be used to generate energy from burning municipal solid waste and discuss the current ways of pollution control for landfills. Can the ash left behind from the burning operations be used, or should it be disposed of in a landfill?

2.  (20 points) Table Format. Suppose an incineration facility costs your city $42.5 million to build. The facility would be capable of burning 675 tons of waste per day producing 15 megawatts of electricity, which can be sold for $0.088 per kilowatt. It will cost nothing additional to take the waste to the facility, as opposed to paying $100 a ton fee to have it buried in a landfill. How long will it take for the waste-burning facility to pay for itself? Ignore operating costs. Assume the facility operates 24/7, 365 days a year.
