After the death of the last female Sumatran rhino in Malaysia, conservationists have been given a glimmer of hope with the birth of a second Sumatran rhino in Indonesia. The 55-pound male calf was fathered by a male named Harapan, and the species is now estimated to be fewer than 50 animals. Conservationists are hopeful that the birth of the calf will help to boost the population of the species and ensure its survival.
