Introduction of invasive species.

Industrial logging threatens many forested ecosystems. Which of the following environmental consequences will most likely result from clear-cutting deciduous forests for logging?

Which of the following would be the best way to mitigate deforestation?

Replant and protect trees in areas that have been previously cleared.

Which of the following would be the most likely explanation for the changes shown in Scenario 3?

Which of the following best describes legislation that could be used to address problems with overfishing?

One way a local community might regulate a shared and limited resource and reduce the tragedy of the commons is to

divide the resources into parcels and assign them to individuals.

The CITES treaty has been helpful in protecting endangered animals and plants by

listing those species and products whose international trade is controlled.
