Because it is worth a lot of money to some people.
They use the tusks to dig into river beds, to get water that's underground during the dry seasons, its called natural selection.i know that but i want to know why do elephants have ivory tusks
Unfortunately, while it is illegal, in many places people still hunt elephants for the ivory from their tusks.
They trample the crops that the villages need to survive so the humans want to kill them because if they have no villages, they will not be able to plant crops or live in a safe place. Eat/drink all of the resources from the land.(water, fruit from trees and plants) There is a set amount of resources that can be shared amongst the humans/animals, so if there are lots of elephants around and reproducing; the humans will want to kill them so that they don't eat/drink all of the resources. They also want to kill elephants because of culling(poaching)
Elephant tusks mainly. It also come from the tusks of Walrus, and Boars.
smugglers and poachers who want the money they can get from dead elephants.
Yes, they are becoming extinctIn 1989, the UN created a plan to help save elephants from becoming extinct. The plan made it illegal to trade ivory from elephant tusks. At the peak of trading, more than 70,000 elephants were being killed every year for their tusks. But after the plan was created, no one could kill elephants or sell their tusks.But now, elephants might be in danger once again. Starting in May 2004, it will be legal to sell ivory. There will be strict controls to monitor where the ivory comes from, but environmental groups worry that increased demand for ivory could mean more elephants will be killed. The current African elephant population is thought to be about 450,000.The governments of several African countries want to begin the legal ivory trade again to help their countries' economies. Ivory is very valuable in trade. But the new ivory trade could be very dangerous for elephants. Their tusks are made of ivory. Hunters sometimes kill elephants just to take their tusks. The wildlife groups will have to work extra hard to make sure elephants don't become extinct.
Poaching of elephants is primarily carried out by organized crime syndicates and individuals who illegally kill these animals for their tusks, which are highly valued in the illegal ivory trade market. These poachers often operate in African countries where elephant populations are at risk, leading to a significant decline in their numbers.
Mankind has hunted elephants for a very long time. In prehistoric times, men went on hunting trips to hunt mammoths, which were cousins to elephants. There are three known species of elephants around today. They are: the African elephant, which has very large ears; the Indian elephant, which has much smaller ears and lives in India; and the recently classified Forest elephant. Over the years, elephants have been hunted for two main reasons: the meat could feed a whole village; and most importantly the two long tusks can be sold for a lot of money. Some other elephant products are leather made of its skin, and there was a time when the feet were used to make umbrella stands. Tusks, which are made of ivory, became so valuable that poachers would hunt and kill dozens of elephants in one night, just to butcher them for the tusks. The rest of the animal would be left behind. This awful practice is so bad that there are very few elephants left in the wild. The sale and trade of ivory has been severely restricted in recent years, but sadly, that has not stopped the illegal killing of elephants. The situation is so bad in Africa, that men who are assigned to protect the elephant herds are allowed to kill poachers when necessary.
Because elephants are not as easily grown as cattle and they cannot be used for meat or milk production such as the cow can. Elephants require much more space than cattle, higher amount of caution due to their size, and are not adapted to colder climates.
As with every other living organism, elephants are made of a variety of cells, tissues and organs. If you want specifics, their tusks are made of ivory. Ivory is a material which is somewhat rare and expensive and is used to make all sorts of things- this being the reason elephants are being overhunted. If you mean Dali's painting it is oil paint on canvas.
What people want is the tusks, rather than the internal skeleton. Elephant tusks are made of a particularly useful type of bone called ivory. Prior to the invention of plastic, ivory was the best material for a wide variety of uses, from billiard balls to piano keys. People sometimes still metaphorically refer to playing a piano as "tickling the ivory". All made possible by elephants.
Ivory is the material found in elephant's tusks. It's slow growing, and basically you only get one set out of each elephant. Simply put there are more people who want some than there are elephants to get it from, so it becomes rare and expensive. Elephants were once threatened by extinction b/c of being hunted and poached for their ivory. These days, in order to save the elephants, all trade in newly made ivory items is forbidden, so all that is left is antiques. The ban on "honest" new production has of course made existing objects even rarer and more expensive, making it more tempting for poachers to target elephants for their ivory again.
