One of the greatest perks of living in AZ is to experience the wonderful saguaro cacti everyday.
I read this in Time the other day:
“National Park Service officials will soon embed microchips in Arizona’s signature saguaro cactus plants to deter thieves who dig them up and sell them to landscapers and nurseries. The microchips, which are inserted with a syringe, will help authorities identify stolen plants.”
Apparently, they sell for about $1,000 each. Talking about microchips, there is substantial research on effective use of RFID chips in OR/MS, for instance, for inventory tracking and control.
