For  this discussion we will examine a case study about the the impact of  climate change on plant reproduction. The plant we will talk about is  the Pinyon Pine. Pinon pine plants are a mast producing species and  their reproduction can be impacted by temperature. In this discussion we  will discuss the impact of increasing temperatures on Pinyon Pine  Production.

  • Complete the post-video lab exercise quiz.

Consider a major biodiversity threat/issue in a specific location (can be at a county, state, or country level). Examples include, but are not limited to: water and soil pollution due to agricultural runoff, loss of habitat due to deforestation, air pollution in an urban area due to heavy traffic, reduced fish populations due to dam construction, increased flooding due to wetland draining and or dam/construction, etc.

For this assignment, you represent a community group and are proposing a sustainable approach to solving this biodiversity problem. Make sure to consider all factors and stakeholders involved and their likely positions towards this community-based proposal. Consider that you are preparing a one-page handout or poster to spread through the community. (This Excelsior OWL resource may help you better understand how to address your audience: Summarizing (Links to an external site.).)

Thus, create an informational brochure such as an infographic or a poster (PowerPoint or a free online infographic tool such as Canva (Links to an external site.) (https://www.canva.com) are both good tools to make posters and infographics). Check this Excelsior OWL resource on presentations with descriptions and examples for PowerPoint: Presentations (Links to an external site.).

Your proposal presentation should include the following information:

• Brief description of the problem (what is the biodiversity threat and how it affects species, ecosystems, but also possibly the human health and the economic system –the effects may be positive or negative)
• Introduction of the stakeholders that have an interest in addressing or maintaining the status quo of the situation that creates the biodiversity threat
• Perceived consequences if the problem is not addressed
• Proposed solution (how, who, when, for how long; include also aspects of how you plan to efficiently communicate and advertise your solutions and involve the stakeholders)
• References (five reliable sources)

Option #2: Weather Disasters

Hurricanes and tornadoes together represent two of the most dramatic and destructive meteorological processes on Earth. For this week’s essay, select one historic hurricane or tornado that significantly impacted humans to discuss. Begin with a narrative of the event—how the hurricane or tornado developed, the path it took, and the damage it inflicted. Be sure to cover its destruction and death tolls, its environmental and economic impacts, and any permanent consequences it caused. Include at least one or more visuals (diagrams, maps, photos, etc.) that make your account clearer to the reader; be sure to refer to the visual(s) in your paper. The length requirement does not include a title page, references page, or any of the visual elements present.
