Section 1: Select the Kitakami River region, the Abukuma Highlands, or Japan's coastal habitat as the ecosystem you want to help with recovery. List the main problem faced by this ecosystem as described in the lesson. Then list at least two sub-problems that need to be considered to solve the main problem. List the sub-problems in order of most to least important. In the rationale column, explain why you placed your sub-problems in the order you selected. Main Problem Sub-Problems Rationale

Section 2: Conduct internet research on your selected ecosystem to help you generate a list of three criteria and two constraints. Your criteria and constraints should consider relevant factors to the problem, such as costs, reliability, safety (to humans and wildlife), human needs, environmental impact, local biodiversity, and the aesthetics of the area. List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale column, explain why you placed your criteria in the order you selected.

Constraints

Criteria Rationale Which Sub-Problems does this criteria address?

Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.

Sub-Problem Proposed Solutions Rationale

Section 4: Answer the following analysis questions about your proposed solutions.

Describe the ways your proposed solutions decrease the negative effects of habitat destruction and human activity on your selected ecosystem.
Describe the costs, safety, and reliability of your proposed solutions, as well as any social, cultural, and environmental impacts your solutions address.
Evaluate your proposed solutions for their impact on overall environmental stability and changes. Which solution has more impact? Explain your reasoning for picking one solution over another.
How could you refine one of your proposed solutions to further reduce environmental impact and loss of biodiversity while also addressing human needs?
