Due Thursday
Read the following case study from Understanding Environment (Jain, 2004, p. 25).
The Real Story: The Day the Cats were Parachuted In
Some years ago, the ABC Health Services sent supplies of DDT to Gyanpur to control the mosquitoes that were spreading malaria among the people. As the DDT was sprayed, the mosquitoes were quickly wiped out. But there were thousands of lizards in the village that ate these mosquitoes (which had absorbed the sprayed DDT) and they, in turn, kept accumulating the DDT in their bodies. When these lizards ate mosquitoes, they also absorbed a lot of the DDT. Due to the accumulation of so much DDT in their bodies, the lizards became very inactive and slow. This made it easier for cats to catch the lizards, one of their favorite foods. At about the same time, people also found that hordes of caterpillars had moved in to feed on the roofing materials of their homes. They realized that the lizards, which had previously kept the caterpillar population under control, were now being eaten by the cats. And now, all over Gyanpur, the cats that ate the lizards died from DDT poisoning. Then rats moved in because there were no cats to control their population. With the rats came a new danger: plague. Officials sent out emergency calls for cats, which were sent in by airplane and dropped by parachute (p.3).
Respond to the following in a minimum of 175 words:
Choose an ecosystem that interests you. Describe the ecosystem you selected and the inhabitants of the ecosystem.
Think about the balance between the inhabitants of that ecosystem. What might happen if one small thing was changed? Choose an example of one change, describe it, and then discuss what the impacts that change might have on the ecosystem.
Considering the change you discussed, what action would need to be taken to reverse the change and restore the ecosystem? Would all impacts be reversible? Why or why not?
Due Monday
Post 2 replies to classmates or your faculty member. Be constructive and professional.

General directions:
Your evaluation should be a minimum of 750 words (most will take more words), using APA formatting and citations. You may need to do some additional research to answer the questions fully. Include the sources in your reference list and at least one in-text citation. 
These evaluations will be graded based on your critical thinking about the case, how your evaluation is organized, grammar, correct spelling/punctuation, etc., and APA citations and reference list. I will make comments on your case study. Check the comments so you do not make the same mistakes on the second and third ones.
Include a word count (not including title or references.) Evaluations will be submitted to turnitin.com for plagiarism checking. 
Specific directions:
Answer the following questions in your evaluation. Answer each question in a separate paragraph and number each paragraph – one per question. You may need to do additional research to answer some of the questions, depending on the case. All 10 questions need to be fully answered. 
Paragraph 1. Provide a short summary of the issue/incident being addressed in the case study – what is it about, what happened, when, where, etc. 
Paragraph 2. Who are the stakeholders and how are they affected? Stakeholders are not just the ‘victims’ but also anyone who could be impacted by the issue/incident. This may include the health care workers, emergency personnel, friends, neighbors, families, governmental agencies, etc. 
Paragraph 3. Explain the background science: What are the technical issues of the case? Technical issues are things like the chemistry of a toxin and it’s toxicity, the lifecycle of a vector and the parasite it carries, the persistence and breakdown chemistry of a pollutant, etc. Whatever is needed to understand why it is a problem. 
Paragraph 4. What is the regulatory framework? These are regulations that relate to the issue (eg Safe Drinking Water standards, disposal permits, etc.), that may or may not have been violated. The regulations could be local, state, national or international.
Paragraph 5. Is this a problem normally monitored for? Who does the monitoring? How was the problem found? By whom and when was it determined to be a problem? Government? Public? Scientist? Doctor? Who first exposed the problem? If not monitored, should it be? How and by who?
Paragraph 6. When was the public notified, if at all? How were they notified? By whom? 
Paragraph 7. What was the response to the problem? Who made the response? When did they respond, and what was the timeline of the response (what were the immediate actions, the long-term actions, ongoing actions, etc).
Paragraph 8. What was the resolution to the problem? How did the problem get fixed, if at all? Is it still a problem? For how long is it projected to continue?
Paragraph 9. Was the response adequate? What else could have been done? What else should have been done? 
Paragraph 10. What measures are being taken to prevent a re-occurrence? What else can be done or should be done to prevent it happening again? 
Note that some of these questions may not be answerable directly from the materials provided. You may have to do some additional research to find the answers. 
Include a reference list of the case and any other resources you used to answer the questions. Use APA format for citations and references.

Please create an info-graphic for the scientific topics I will provide when assigned.
MUST have scientific background and experience in creating visual aids/infographics from SCRATCH. (example: through canva)
I will also provide my notes/background information on the topic – If are knowledgeable and comfortable with BOTH environmental
sciences & creating digital info-graphics, it will be a simple task – you will need little to no extra research to complete this assignment based on the information I attach.

I want to write a mini-review article on the above topic. I have attached the format of the mini-review.

Discuss the chosen environmental issue, its impact on the community, and the connection to “Do the Right Thing.” Analyze data and provide evidence to support your claims. 1. Choose an environmental issue: Research environmental concerns in NYC neighborhoods, focusing on areas with high minority populations and low socioeconomic status. Examples include:
○ Asthma rates and air pollution in North Manhattan communities like Harlem.
○ Location of waste transfer stations and their impact on surrounding
neighborhoods.
○ Lack of access to parks and green spaces in low-income communities.
2. Data collection: Utilize reputable sources like NYC Department of Environmental Protection reports, academic journals, and community organization websites.
3. Film Analysis: Identify scenes in “Do the Right Thing” that connect to the chosen environmental issue. Consider elements like:
○ The constant heat wave throughout the film and its impact on characters.
○ Sanitation issues and overflowing garbage cans.
○ The lack of trees or green spaces in the neighborhood.
4. Solution Proposal: Develop a plan that tackles the environmental issue and promotes environmental justice. This might include:
○ Community gardens and urban greening initiatives.
○ Advocacy for stricter regulations on polluters.
○ Investment in clean energy infrastructure in underserved neighborhoods.

Need to develop a ppolicy for PCB (polychlorinated biphynls) for a local utility. 
the policy has to follow and comply with the relevant federal regulations such as TSCA implemented by the EPA and state level regulations implemented by CA DTSC. The pollicy should be written in a manner accsessible to staff that would be using it in the event of a release who are not policy makers/experts. 
The policy needs to provide a set of pathways that allow for swift respods to spills/releases so that the response does not require major involvement by the EPA. 
Essentially the policy needs to answer the following:
-what to do
-who/how to report an incident/release to
-how to characterize materials for PCB wether the conc is known or unknown
-clean up procedures within the applicable regulatory reirements based on the characterization and relevant determinations.
Included are example documents from other agencies. Not inclded are TSCA and other regulations.

I will upload all instructions
Overview – As we reviewed in the previous module, food scenes in film can provide the audience with significant contextual clues into the characters’ emotional status, socioeconomic background, and cultural history.  In this module, we will use that knowledge to explore a side-by-side comparison of 2 distinct cultures showing the same food media.
