...and That Just May Be a Very Good Thing. Christina Butler from Georgia, United States Creative Commons Attribution 2.0.

These shifts in a species' distribution in response to environmental change are normal and so fine and dandy. Under certain circumstances, these species can cause ecological harm. When human activity is involved with these migrations, triggering or facilitating geographic shifts, we label them with the judgmental handle, Invasive species.
