But then, to further complicate matters, President Donald Trump tweeted Friday evening that nothing would actually change until he “reviews all conservation facts.”

The idea that killing more elephants will help save the species is counterintuitive, and its line of reasoning is difficult for many conservation organizations to support: Let rich hunters pay hefty sums to shoot elephants, and use the money to help conservation efforts and local communities. Supposedly, the villagers won’t then need to poach elephants to feed their families and pay their kids’ school fees. Still, the International Union for Conservation of Nature, or IUCN, a respected organization that sets the conservation status for all species, supports the notion.

But the evidence that “hunting elephants saves them” is thin. The hunting-safari business employs few people, and the money from fees that trickles down to the villagers is insignificant. A 2009 report from the IUCN revealed that sport hunting in West Africa does not provide significant benefits to the surrounding communities. A more recent report by an Australian economic-analysis firm for Humane Society International found that trophy hunting amounts to less than 2 percent of tourism revenue in eight African countries that permit it.*

And then, there is a larger moral question: How does hunting affect male elephants, especially the “big tuskers” that hunters want, and the overall population?

If elephants are recognized as legal persons, a term the U.S. courts have granted corporations and a New Zealand court gave to a river (elsewhere the term has been extended to chimpanzees, a bear, and the environment), it would be more difficult to hunt them at all—let alone import their body parts. Wise’s lawsuit cites extensive scientific studies that have established elephants’ cognitive abilities, emotional and empathetic natures, complex social lives, lifelong learning, and memory skills. “Taken together, the research makes it clear elephants are autonomous beings who have the capacity to choose how to live their lives as elephants,” he tells me.

One thing elephants would not choose, Wise and elephant researchers agree, is to be hunted. “It doesn’t matter to elephants if they are killed by poachers or trophy hunters,” says Joyce Poole, who has studied African elephants in the wild in Kenya and Mozambique for more than 40 years and is the codirector of ElephantVoices, a conservation organization. “Either way, you’re a killer. And if elephants understand that about you, they change their behavior.”

Elephants aren’t considered game animals in most African countries with substantial populations of these animals. But trophy hunters after large male elephants can seek their prey in South Africa, Namibia, Cameroon, Zambia, Zimbabwe, Tanzania, Gabon, and Mozambique. Kenya banned the sport in 1973, while Tanzania continued to permit legal hunting. That caused problems for the elephants of Kenya’s Amboseli National Park, says Poole, who was studying the large males in the park at the time. The park borders Tanzania, and after the Tanzanian government opened a hunting block on the opposite side, the Amboseli male elephants who wandered across became prized targets.
