I support elephant conservation (http://www.sheldrickwildlifetrust.org) and have a book about elephants When Elephants Weep (https://www.amazon.com/When-Elephants-Weep-Emotional-Animals/dp/0385314280/ref=sr_1_1?ie=UTF8&qid=1511020821&sr=8-1&keywords=when+elephants+weep&dpID=61YzfhGXWRL&preST=_SY291_BO1,204,203,200_QL40_&dpSrc=srchthat) describes how intelligent they are.
There must be a way to protect elephants other than killing them. I went on a safari...the locals made money and no animals were killed by me.
Well, if you find a way to protect them without making them economically viable, let me know. Guides policing their hunting area is the best there is.
Kenya has tried the camera safari thing, to the destruction of their wildlife by 70%.
First you have to understand nature, just because none are hunted, they will still all die, as will you and I.
