A century ago, their global population was more than 230,000. Now there are about 104,700 Bornean (critically endangered status), 7,500 Sumatran (critically endangered status), and only 800 Tapanuli orangutans left. But there is still hope because these 16 incredible animals came back from the brink of extinction!

There are only 4,000 Kordofan and Nubian giraffes left, according to the IUCN. The reticulated giraffe is also listed as endangered. The giraffe population has declined primarily due to loss of habitat, civil unrest, and poaching. Some giraffes are killed just for their tails, which are considered status symbols in parts of Africa.
