Examples of data on the impacts of human activities could include the quantities and types of pollutants released, changes to biomass and species diversity, or areal changes in land surface use (such as for urban development, agriculture and livestock, or

Science and Engineering Practices - 9-12.SEP6.3:
Refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.

Disciplinary Core Ideas - S.HS.ESS.3.4.DCI:
ESS3.C: Human Impacts on Earth Systems •Scientists and engineers can make major contributions by developing technologies that produce less pollution and waste and that preclude ecosystem degradation. ETS1.B. Developing Possible Solutions •When evaluating solutions, it is important to take into account arange of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts.
