Elephants in Angola learn to avoid landmines

Elephants in Angola seem to have learnt the art of avoiding landmines. There were almost no incidents of elephants being blown up by landmines in the past. Radio collar tracking of elephants have also confirmed the same. How the elephants do it is still a mystery. Some speculate that they use their keen sense of smell to smell landmines, while others say that elephants learn from seeing other elephants being blown up.
