Conservationists (people who want to protect animals and the Earth)
say poaching will stop if it is unprofitable.
If the killers cannot make money,
they will not kill elephants.
A conservation group said
: "Any time we can remove ivory from the marketplace, it's a win for elephants."
A worldwide ban on selling and buying ivory started in 1989. It has helped elephants, but the world needs to do much more.
