Question

Humans built dams, dikes, and levees to control water flow and flooding in the Florida Everglades. This allowed us to expand urban and agricultural areas, but it also allowed invasive species to take over and destroy habitat for native species, as well as reducing native species ability to move to find resources and reproduce. Restoration efforts are under way to allow for natural water drainage and to treat the water.

Which size impact does this human-led destruction of habitat have?

Small because they are restoring the original hydrology by removing interior canals.

Medium because only some species were affected by the changes.
Medium because only some species were affected by the changes.

Medium because many species were impacted, but they are still surviving in the remaining areas.

Answer 1

The correct response is:

**Large because it has led to several significant changes, including new invasive species and loss of natives.**

This choice reflects the considerable and lasting impact that human alterations have had on the ecosystem, including the introduction of invasive species and the loss of native species, which are both critical components of the habitat.
