The rhinoceros family contains five species, the Indian, Javan and Sumatran, which all live in Asia, but the black and white rhinos live in Africa. All these rhinos look differant with distinctive features, e.g. The Black Rhino has two horns, but the Indian rhinos have only one Horn.
In the 1960's, scientists estimated that were approximately 100 000 black rhinos in Africa, but a count in 2003 showed that there were approximately 3100, the population has decreased so rapidly because of the demand for the rhino horns. The black rhino is already extinct in some places, in the others it will be likely that they could be extinct very soon.
Rhinos are no near dangered from wild animals then humans, the humans kill rhinos for their horns. The poachers (the people who kill rhinos for their horns) use various techniques for catching the rhinos, they usually use wire traps or snares, the snares are a slow painful death, but some poachers will just use machine guns for a more quicker and efficient death. These traps are usually placed between water holes, on their tracks or on their home-range. The horns are cut of by either machetes or chainsaws.
The Black Rhino
To dehorn a rhino a vet has to simply shoot a rhino with a tranquilizer dart so it falls asleep and than the horn gets cut off. Although the horns are important, rhinos can still survive without them. A problem with dehorning a rhino is that it is expensive to hire vets who will do it. But it is not a one-off thing either, it has to be repeated every few years as the horn can regrow at a rate of around 7cm per year.
The Rhinos Endangered Habitat
The number of people on earth is increasing, meaning more people need the land to live and work on, and food to eat. This means that the natural habitats are being destroyed and many wildlife populations (including the black rhinos) have decreased quickly. When habitats are destroyed people are usually happy as it means new jobs may be made. But when the land is cleared and the habitat is destroyed, it can lead to other problems as well, like if the land is used for mining, it may cause poisonous waste which can pollute rivers and land.
Preserving The Habitat
To preserve the habitat of the rhino and other endangered animals, conservation workers make protected areas. The conservation workers try to make the protected areas as large as possible so it can support other animals as well; but setting up the protected areas is difficult as it may be expensive to buy the land and it will also be very expensive to employ wardens and their equipment-vehicles, uniforms etc..
Conclusion
There is a lot of effort being put in to save rhino's by many people, but still, so many populations of the rhino are endangered. Sadly scientists think that the rhino could be extinct by 2002. This means within the twelve years a lot more effort needs to be put in, poachers need to understand that their are alternatives to killing rhinos for their horn, especially now that land is being cleared it opens many new jobs that need to be done.
