Giraffes

IUCN(世界自然保护联盟）has put some giraffes at a critically endangered(淑危的）status. There are only 4,000 Kordofan and Nubian giraffes left. The giraffe population has declined primarily due to loss of habi-tat，social disorder, and poaching(偷猎）according to priority(优先考虑的事）.Some giraffes are killed just for their tails，which are considered status symbols in parts of Africa.
