An illegal trade in ivory thriving in the UK is threatening elephants.
The International Fund for Animal Welfare (Ifaw) says nearly all the ivory in the UK is sold illegally, because of "worrying" holes in the law.
Only ivory carved before 1947 can be sold in the UK, but Ifaw say dealers fake age documents for new ivory, which means more elephants are being killed.
Selling ivory from elephants that weren't poached could be legalised soon, but Ifaw is trying to stop this.
