A truly absorbing read. Based on meticulously sound scientific research, Wild Health by Cindy Engel is also easily accessible to the general reader. It's tightly written and densely packed with absolutely fascinating information. The author peels back a layer I didn't even know existed, looking behind the usual way animal behaviour is presented to the deep instinctive wisdom that enables wild creatures to keep healthy and to treat their own wounds and diseases. I love the positive approach of this book - so often we think of keeping healthy only after disease has struck. Why are humans so thick? Many of the examples of animals self-medicating are unforgettable. A man in a South American rainforest attacks a snake that invades his hut by beating it with a stick - but the snake keeps coming back with its wounds healed. The man starts to follow it and observes that after every beating it rolls in a particular plant to heal itself. Then what about the elephants who risk their lives walking a narrow path by an abyss to get to a clay pit and eat the clay? The clay provides them with essential minerals, and even though some do fall into the pit, the health of the herd is assured. But my favourite was the story about giraffes eating acacia leaves. As the acacia tree is eaten away and its life starts to be endangered, it manufactures a substance in its leaves that makes them bitter, and the giraffes stop eating it. Not only that, the tree gives off an airborne a chemical messenger that lets other acacia trees in the vicinity know what is happening, and they begin to turn their leaves sour in advance of getting eaten. Result: giraffes move off to find fresh trees. So not only are the trees saved, the giraffes are guaranteed a fresh supply of leaves when they return to those same acacias the following year. So probably trees are smarter than humans too. I could go on and on - but get the book yourself - what we want now is a film please, Cindy!
