discuss sumatran rhino

Answer 6

most threatened rhino due to hunting for horns and habitat loss
popn declined by 50% in last 15 yrs
only 100 left in 2013
conservation focused on captive popn rather than threats but dont breed in captivity and often die during capture

give some pop stats for sumatran rhinos
