(Radio Iowa) – A new book by an Iowa author implores people to preserve the waterways that sustain our crops — and our lives — by tackling tough issues from climate change to nitrate pollution. Professor Neil Hamilton, who recently retired after 36 years directing the Agricultural Law Center at Drake University, uses the river as a narrator in his book, “The River Knows.” He says the book is designed as a wake-up call to make people stop and think about our waterways and how we can best protect them. It’s the sequel to Hamilton’s 2022 book, “The Land Remains,” where Iowa’s fertile, underappreciated soil told its own story.

The book is available at many Iowa bookstores and through the publisher, Ice Cube Press.
