Question:

How should the first paragraph of a paper proceed, and why is it important to the rest of your essay?

Callie L.
Answer:

The introductory paragraph of a paper should not only introduce a reader to a topic, but also give the reader a solid grasp of what you will be talking about in the rest of the paper, including your main arguments and a quick list of support. The introductory paragraph should begin with a hook, such as a question or interesting fact, that gets your reader interested in what you have to say by wanting to know more. The introductory paragraph should also include relevant background information, just a few sentences, that give the reader basic background information so they understand both the relevance and importance of the subject you will be speaking about. Furthermore, the introductory paragraph should include a thesis statement that summarizes the main argument of the essay in relation to the topic you introduced earlier. The thesis statement should be significant enough to show why your argument is important. Thesis statements help focus your argument. Lastly, your introductory paragraph should act as a roadmap to the rest of the essay. There should be a sentence that introduces, in just a few words, what evidence or materials you will be using to support the argument laid out in the thesis. This roadmap will not only help readers understand the organization of your essay, but also help you when writing it by giving you an outline to follow.

Question:

What is a keystone species and how do they impact the environment?

Callie L.
Answer:

Keystone species can be thought of as the most important species in an ecosystem. They are essential to the overall health of the ecosystem. They play a very important role in the ecosystem, and their removal has extensive and profound effects on the function and diversity of an entire ecosystem. Without the keystone species, an ecosystem could change completely, or even collapse. A classic example of a keystone species is the wolf in the Yellowstone ecosystem. The government was worried about wolves harming farmers' herds of animals such as sheep close to Yellowstone, so they captured and killed all wolves in the area. However, when wolves were removed, populations of animals like elk and deer exploded. The booming elk and deer populations trampled plants and increased soil erosion in Yellowstone. Since plants were trampled, smaller herbivores had less food to eat and their populations decreased. The entire ecosystem was changed as a result of the removal of wolves from Yellowstone. Once wolves were reintroduced, the populations recovered.

Public Policy

Question:

What are the main reasons for policy intervention? Be sure to provide examples of each.

Callie L.
Answer:

Typically, the government takes action to implement policy for political, moral, or economic reasons. An example of a moral or ethical reason for policy intervention is abortion policy in the United States. Many government leaders believe that life begins at conception, and it is wrong to terminate a pregnancy. Therefore, they implemented policies that make it harder for women to have access to abortions. For example, some policies require hallways in abortion clinics to be very specific widths, which can both make it difficult to build new clinics and force existing abortion clinics to shut down. Policy intervention can also be a result of an economic situation. When the private market does not take care of a situation or creates an unfair situation, then the government can create policies to resolve this. For example, there are many policies to prevent monopolies in markets, such as cell providers. The government could prevent AT&T and T-Mobile from becoming one company because they would control most of the market and be able to charge people a lot for cell service. Political reasons are another reason for policy intervention. Government actors may support policies that protect their own country against others, or even their own political parties. For example, if the United States and Canada had a disagreement over how to handle an international crisis, the US might put tariffs on Canadian goods to make the much more expensive to import into the US. This would hurt the Canadian economy. The US would do this in order to encourage the other country to switch to their side on different matters.
