Clarification Statement - S.HS.LS.2.7.CS:
Examples of human activities can include urbanization, building dams, and dissemination of invasive species. Examples of solutions could include simulations, product development, technological innovations, and/or legislation.

Science and Engineering Practices - 9-12.SEP5.6:
Create or revise a simulation of a phenomenon, designed device, process, or system.

Science and Engineering Practices - 9-12.SEP6.4:
Design, evaluate, and/or 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.LS.2.7.DCI:
LS2.C: Ecosystem Dynamics, Functioning, and Resilience •Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species. LS4.D: Biodiversity and Humans •Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction). (secondary to HS-LS2-7) •Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value. (secondary to HS-LS2-7) ETS1.B: Developing Possible Solutions •When evaluating solutions, it is important to take intoaccount a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts. (secondary to HS-LS2-7)

Crosscutting Concepts - CC2.8:
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.

Crosscutting Concepts - CC6.6:
Much of science deals with constructing explanations of how things change and how they remain stable.
