What will happen when the petroleum runs out? This book will teach you how your grandparents used plants in their daily lives before oil came along.

Barely 70 years ago, petroleum and its countless derivatives were not that present in our daily lives. It seems inconceivable today, but travel was on horseback, roofs were made of thatch, our clothes were woven with hemp and flax, and toys were made with local flora. Plants were an essential resource: renewable, local, and within everyone's reach.
In this book of suggestions for green resources, you’ll find a general survey of our cultural heritage through 75 profiles of useful plants.
Species by species, you’ll discover how the plants gave us the best they had to offer, enabling us to do without oil for millennia. Food for thought about the future!
