Strange Harvests follows Edward Posnett as he travels the world, looking into seven incredibly obscure animal/plant products, and exploring the sustainability (social, economic, environmental) aspects surrounding them. This book asks the question: can we, as modern humans, find a nondestructive way to profit from the environment without harming it.
Back in high school, I did a curiosity cabinet project for Jane Eyre, so I was intrigued that it was the framing device for this book. Posnett goes about creating his own collection of items, a more positive echo of Britain's archaic and slightly concerning "collection" practices from back in the day. However, he goes deeper than the cabinet he creates, because the better curiosity cabinet is this book, made up of a depth of knowledge about each object and a greater understanding of how humans fit into this world.
My personal favorite chapters here were on byssus (sea silk), and vicuna wool. Both presented incredibly rich and nuanced histories of the socioeconomic factors surrounding each item, and extrapolated interpretations of the present day from those histories. Overall, though, each chapter presents a compelling narrative story along with the information it presents, and I honestly would just recommend you check it out for yourself.
The one thing I found off-putting about this book at times was that Posnett's tone often dips into the "look but don't interfere" realm popularized by BBC Nature documentaries. I personally don't love this rhetorical style, because I think that in the long-term it leads to a general lack of action on environmental issues. (BUT after having listened to several nature books lately, I have to admit that this is just the rhetorical style of the genre, and I really can't fault Posnett for going with it.) I do, however, really like that the author doesn't shy away from the fact that he is idealistic, and that his idealism has shaped his travels.
If you love learning about super obscure systems and ecologies, then there couldn't be a better book for you.
