a devastating landslide happened in Afghan 2 May

the region is so vulnerable that there is a high possibility to have a landslide

keepers sometimes need to ensure the animals feed their kids in an appropriate way

if the species is endangered, keepers should keep the kids from their mother to ensure kids can live and then return them to their social groups

the challenge will be reintroducing the kids to other sloth bears

the population of cubs is growing
