Guiding Question 8.4

In what ways do human actions affect ecological communities, and how can we take steps to help restore damaged ecosystems?

Why You Should Care

Often, human activity disrupts the relationships between organisms in ecosystems and reduces their function, and it can take decades to determine what went wrong, why it happened, and how to correct the problem. Sometimes the effects of human activities are enough to make area uninhabitable. Sometimes, they jeopardize important resources and ecosystem services that usually aren’t fully appreciated until they are lost. Billions of dollars are now being spent to correct past mistakes, from the draining of the Everglades, to deer overpopulation, to the introduction of invasive sport fish. Billions more could be spared by understanding better how to avoid the problems in the first place.
