species is a non-native plant/animal introduced accidentally or intentionally by humans 

• extinct

• endangered

• threatened

• invasive (exotic) 

Why is genetic diversity important?

• A population with less species  diversity is more likely to survive an outbreak of disease since less species means less chance of disease spread.

• A population with less species  diversity is more likely to survive the competition among species.

• A population with more genetic diversity is more likely to survive environmental changes, a disease outbreak, or the disappearance of a food source.

• A population with less genetic diversity is more likely to survive changes food supply and demand.
