At the peak of the rhino poaching war in South Africa in 2015 and 2016, poachers slaughtered nearly three rhinos a day. Although that rate has declined, the numbers are still disheartening and unsustainable, with poachers killing at least one rhino every day. Some conservationists have looked to drones as a potentially powerful tool in anti-poaching efforts, with the technology continuing to evolve. But experts say it isn’t at the level yet where it can meet the challenge, and that while it can be helpful, conservation efforts must continue to engage and educate local communities.
