In South Asia, in countries like India and Pakistan, four species of vultures are listed as critically endangered, which means they have less than 10 or 15 years to go extinct, and the reason is because they are falling prey by consuming livestock that has been treated with a painkilling drug like Diclofenac.
U Južnoj Aziji, u zemljama poput Indije i Pakistana, 4 vrste strvinara vode se kao kritično ugrožene, što znači da imaju manje  od 10 - 15 godina do istrebljenja, a to je tako jer ugibaju zbog hranjenja stokom koja je tretirana sredstvima protiv bolova, primjerice Diclofenacom.
