Why is it useful to know the background level of extinction?
It is part of the scientific process to observe changes in nature.
If current rates greatly exceed background rates, scientists say there is a chance of a
mass extinction event happening.
NOAA and FWS are required by law to compare background rates to current rates.
Scientists want to see if increased extinction rates will threaten the human population.
