Catching poachers is great and all, but the poachers themselves are only the supply side of the problem. Demand for poached animals has increased in parts of Asia where members of a growing middle class use animal parts for herbal remedies, Time reports. That has created a wildly lucrative market for items such as elephant ivory and rhino horns. According to Time, wildlife trafficking is now a $7 billion to $10 billion industry. To really stamp out poaching, you need to eliminate the incentives and organized crime rings that form around it--unfortunately, something no camera system, no matter how sophisticated, can do on its own.
