Unhealthy Conditions
Some invasive species really know how to stir things up. The Norway rat, which is actually a rat from Asia, first arrived in the United States around 1776. Just as colonists were attempting to build our nation, the Norway rat was starting its own colonization effort, which continues to this day.
