Humans are elephants only natural predator. Every year thousands of elephants are killed for their tusks. Ivory is hard to come buy and extremely expensive since people can't get it when they need to they result to poaching. This has become a huge issue, so now scientists are trying new things to keep elephants from beimg killed. There is talk about a chemical being using on elephants tusks that isn't harmful to the animal but will make the ivory useless. It would be a huge break through and accomplishment to have this being used as soon as possible.
That's a cool idea hope it is effective if they decide to use it.
