When there is an animal that people love its fur, skin, horns or other body parts to use for clothing and other items, these animals’ lives are threatened. These body parts are worth lots of money and many poachers will kill these animals whether it is legal or not in order to make a lot of money. The same can be said for the rhino and especially the white rhino.
Poachers were known to kill these animals for their horns. Now they have become extinct since they were killed in a short period of time. The white rhino could not have been saved because they were located in one small area and it was difficult to control the poachers in Africa.
Although technically, white rhinos are not extinct, things aren't looking good for the species. There are only two females left on the planet which means no natural opportunity for mating to occur. However, scientists were able to harvest sperm from Sudan, the last male rhino that died in March of 2018.
This means that specialists are in the process of attempting in vitro fertilization by removing eggs from both females in hopes for a successful pregnancy. Unfortunately, it seems as though the technology came about too late and it may not be functional. In short, humans didn't prevent poaching or care enough to take care of the species until it was too late.
