Why are panthers endangered species?

because alot of people are killing them and shot them in the forest jk i dont know
Pumas were severly persecuted in the 1800's in the east, and the Florida race is the only eastern puma to completely escape extinction.
The Florida panther is a subspecies of the mountain lion, also called puma and cougar. Hunting devastated the eastern populations, til only a handful were left in the swamps of Florida. Inbreeding was becoming a problem, and, with only thirty pumas left in Florida, a decision was made to bring in eight female Texas cougars, another puma subspecies very close genetically to the Florida race. The program worked, and the inbreeding has been stopped, for the most part, and now 80 pumas roam there.
