Oddball Reseachers Use Data and Guns to Save African Elephants

A small group of American and British scientists go to East Africa to try to save elephants from poachers and to find how many remain. They end up fighting with poachers, large and small groups, who try to kill them, meanwhile being chased and threatened by elephants and having to shoot some to survive.

Based on real research and attempts to save African elephants, in this book you will meet some of the strangest characters in the world, the kind of people who can’t survive in normal society and, with their odd behavior, retreat to wilderness.
