A recent survey of savanna elephant populations estimated that poachers killed 30,000 animals annually between 2007 and 2014, reducing the population to fewer than 400,000. Overall, researchers estimate that African elephant numbers have plummeted more than 95% over the past century.
[...] Zimbabwe, Namibia, and South Africa—are expected to offer proposals for restarting a legal ivory trade. All argue that some elephant populations are healthy enough to be managed for ivory production. The proposals envision taking tusks from both animals that are intentionally killed—sometimes because they become nuisances, trampling crops and threatening people—and those that die naturally.
A study in Current Biology concludes that the demand for ivory far exceeds any sustainable harvest model and that there is a high risk that lifting the ivory ban will make things worse. The authors note that attempts must be made to reduce the demand for ivory:
At the same time, we cannot brush aside the fact that poaching has reached industrial scale fuelled by an increase in consumer demand driven by the rise of the middle class in countries like China. We must urgently work on finding ways to change consumer behavior as the only avenue by which we can resolve the ivory trade tragedy.

There are giant stockpiles of ivory sitting in warehouses, waiting to be burned. If slowly released onto the market at a slightly lower price than the black market, not only could the ivory stockpiles become a lucrative source of income to a country, but poaching of elephants should drop drastically due to the lowered price of ivory.
And when the warehouses are empty, poaching starts anew. Great plan.

The idea is that the stockpiles could be used to let the elephant population recover without being poached.
The problem with elephants is they tend to over-populate an area surprisingly rapidly. When that happens, they are culled.
A few decades ago you could buy canned elephant meat (as pet food) from Kruger Park [wikipedia.org].
If you're culling elephants regularly, one may as well sell their tusks. The proceeds can go to managing the game park more efficiently, benefiting everyone.

I should add that a female elephant's fertility's linked to fat levels. If a female elephant's fat levels drop below a certain level (I think it was 30%), she becomes temporarily infertile. Once fat levels reach or exceed the minimum amount, she becomes fertile again.
The problem with this is that an elephant will keep bearing young until she starves or dies. Starvation means the elephants have eaten everything they can find, almost creating a desert. (they will uproot a tree to get to the uppermost leaves).

If anything I've seen the reverse at walmart.
I'll admit it could be simple orbital mechanics, the kids just cant break free of the gravity field.
