ICE Princess25 [194]

Answer:

E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.

Explanation:

E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.

Nowadays there is a lot of technology available for tracking and monitoring of wildlife in big areas. If these radio collars are falling off very frequently and the tranquilizer is being used a lot, it means the method they are using is not the best or very efficient for this type of big animals.

They can use for example GPS trackers in a microchip implanted below the rhinoceroses skin or <u>even inside the horn</u>. With this process the park rangers would just need to use the tranquilizer once to immobilize the animal for a little bit, implant the GPS tracker or microchip; <u>this device won't fall or slip off and won't do </u><u>any harm</u><u> to the rhinos either</u>. This procedure will reduce the risk of the collar falling off and the use of the tranquilizer every time it does fall. Additionally, with this trackers, the park rangers, supervisor or vet can access the information <u>24 hours a day, in real-time</u> from a computer or even an electronic device. This new technology even offers an alarm systems by SMS or calls every time an abnormal rhino activity is detected.
