Decline in Elephant Population

There is a decline in the elephant population in a specific area in Africa. You are an activist trying increase the elephant population. You are required to present a proposed solution to this problem. Create a proposal to solve this elephant problem. Please include the following:

Background Information. (Describe the main biome where elephants are located; describe an ecosystem, and describe 4 other types of biomes)

Name and discuss how elephants are threatened in Africa. (Research)

Discuss how biodiversity can affect the increase and decline of the elephant population.

Differentiate between the types of population growth models that can increase or decrease the elephant population.

Discuss how community populations relate to your proposal.

Evolution

Answer disscussion board question in 2 paragraphs see question below and use attached articles to cite and support your answer.

QUESTION: There are many forces (drift and selection for example) that bring about evolutionary change. How do scientists connect the mechanisms discussed in the Futuyma essay to the topics discussed by Thompson and Raff? Use examples to illustrate your points.

India: The World’s Most Populous Country?

It is nearly a certainty that India will overtake China as the world’s most populous country–by 2025.

India’s population growth is also too high, and needs to be slowed. Discuss why you think India will have a harder time slowing it–harder, certainly, than China.

Prompt
Using well-selected evidence from Nathaniel Rich’s article : “Losing the earth”, the documentary Merchants of Doubt*, and providing careful and clear reasoning, answer the following question:

If Nathaniel Rich had published his article this August, just before the Presidential elections, rather than in August 2018, just before the Midterm elections, would the article succeed in persuading voters to go to the polls to cast their votes based on a desire to protect the earth’s climate? What might keep voters from this choice? Does Rich’s article overcome the continued claim that there is “no scientific consensus on the cause of climate change”? or can readers still maintain this claim after reading “Losing Earth”?

Ask yourself the following questions:

What is the most persuasive evidence that Rich provides in his article?
What is the least persuasive evidence that he provides?
Does Rich do enough to reveal the “selling of doubt” that fossil fuel companies have funded?

In your conclusion, tell us: What do you think reluctant voters would need to hear to persuade them that the climate is worth protecting?

Include at least one image (it can be a graph, a photo that illustrates an issue you’re discussing. Avoid generic images representing climate change. Choose an image that is directly relevant to a specific idea you’re discussing, for example, the Keeling Curve.)

– Nitrous oxide [10024-97-2] 25 ppm & 45mg/m^3
– Nitrodiphenyl [92-93-3]

Investigate and report on one of the chemicals, only using the headers and shown here below:

Chemical name: List your chemicals name, and its CAS Number [CAS no.]       

Hazardous physical/chemical properties: Describe the basic properties and those that contribute to make your chemical hazardous to humans. Provide specific data from your sources, and explain in plain language. You must link together the provided data and your related comments about hazards.

Routes of entry: Describe the routes of entry of your chemical into the body (link each route to the expected states of the chemical).

Effects on the body: Describe the effects on the human body.

Sources of exposure: What Industries and/or processes use this chemical?

Control Measures: Describe the measures required to safely control your chemical in the workplace, beginning with Pre-contact controls: {Engineering, Policy & Procedure, Administration & PPE} and concluding with post-contact controls: {First Aid, Fire Fighting & Accidental Release measures} (Cover all)

SDS (Safety Data Sheet) Upload a copy of one (1) complete SDS. In your SDS, your chemical must have at least 80% concentration.

Bibliography:
– Must cite at least 5 sources from the Internet, including ONLY 1 SDS
– Do not use other sources (textbooks, notes, magazines).- Must use MLA or APA style for internet citation
