This lesson discussed the engineering design process and the devastation of three ecosystems: the Kitakami River region, the Abukuma Highlands, and Japan's coastal habitat. In this activity, you will select one of these ecosystems and follow the steps of the engineering design process to design a recovery solution. Complete each section of the Recovering Ecosystems Worksheet, including the problem, sub-problems, criteria and constraints, and proposed solutions for ecosystem recovery. Instructions for each section are included in the worksheet. Be sure to review the assignment's rubric before completing and submitting this assignment.
