Opis

For most people today, bones reach the trash bin and landfill and urine trickles down the toilets into the sewage system. We know that our primitive ancestors used bones for tools and possibly weapons especially when living in caves. In the past, we had a rag and bone man with a sack or cart collecting bones to grind up for fertiliser. With a lack of water our primitive ancestors may have used urine for drinking, washing and even cooking. They may also have discovered that putting urine on injuries could act as an antiseptic or a sterilising chemical. This book looks at how we used bones and urine in the past and the ways we can still use these today as a valuable recyclable resource
