Review Unit 5

Decreasing the availability of natural resources will have a good impact on human activity.

• True

• False

Decreasing the availability of natural resources will have a bad impact on human activity.

• True

• False

Natural hazards will have a bad impact on human activity.

• True

• False

Natural hazards will have a good impact on human activity.

• True

• False

Humans are creating negative feedbacks to the environment causing for design solutions to no longer be needed.

• True

• False

Design solutions are creating positive feedbacks to the environment and humans are the negative feedback that will help the environment.

• True

• False

Humans are polluting the environment creating a positive feedback, but scientists and engineers are creating design solutions to create negative feedbacks to help the environment.

• True

• False

Select the statement that best explains this cost-benefit analysis: The benefit of making energy from any element on Earth using nuclear energy outweighs the cost of its safety concerns compared to other form of energy production.

• The safety of a nuclear power plant is dangerous but there is only progress that can be made on that front and once the progress is made then we have unlimited source of elements to make clean energy.

• Since Earth is made up of elements that is good and that will be helpful for nuclear energy.

• The safety of nuclear power plants is not a big deal because they have never harmed anyone so it is the best source of energy.

• The safety of nuclear power plants is too dangerous and the unlimited amount of elements on Earth is not important.

What is a good equation for a computational model for an ecosystem?

• Biodiversity=Constant*Technology+Management of Natural Resources

• Management of Natural Resources=Constant*(Positive Feedback before technology-Negative Feedback after technology)

• Human Sustainability=Constant*Biodiversity*Management of Natural Resources*Technology
