almost every day, frik rossouw and his team have to go out to secure crime scenes like this one. in this case, it's especially distressing. the rhino, a female, was pregnant. narrator: hunting and being hunted -- for wild animals life is always about survival. and it's no different in kenya. in some of the villages here, people and elephants are sworn enemies. and that's where a very special story begins, the story of elephants whose survival is all down to bees. reporter: farmer nashon mwaghare has finally been able to harvest numerous sacks of corn. he leased the field ten years ago, when his first child was born, but a powerful enemy appeared, one that constantly stole his harvests. nashon: we would sow the seeds, but just before harvest time, the elephants would come. sometimes they came before the corn was even ripe. they would eat everything or trample it. everything was destroyed. reporter: they always came during the night and tore up the field. it was a desperate struggle between humans and animals over land and sustenance, a struggle that claimed victims on both sides.
