Beavers are back in the UK, hundreds of years since they last lived among us. Brett Westwood asks if we can recover our cultural links with these architectural animals, as well as remember how to live with the changes they bring to the landscape. Nature writer Jim Crumley talks about their green engineering skills and writer Rachel Poliquin brings the Canadian perspective on what she calls the four great human romances with the beaver: with its castoreum, its musk, its architectural skills and its ecological abilities. Original Producer Beth O'Dea.
