Invasive Species (2006)
Thumbnail Image:

Description:
Invasive species may be defined as a non-native plant, animal, or microbe whose introduction causes, or is likely to cause, harm to the economy, the environment, or human health. Increasing globalization—the rapid transportation of people and goods throughout the Earth—provides the opportunity and the mechanism for such species to enter the United States and thrive in new habitats. Each year, the U.S. incurs direct losses of approximately $120 billion dollars due to these invasive species—an annual cost greater than most natural disasters combined.
