Over 10 years, it drops to 1400. Species become endangered for two main reasons: loss of habitat and loss of genetic variation.Loss of HabitatA loss of habitat can happen naturally. The risk of extinction for the endangered Florida manatee appears to be lower, according to a new U.S. Geological Survey led study. For this reason, fewer offspring of inbred groups survive to maturity.Loss of genetic variation can occur naturally.
