Threats to the natural world are the focus of today’s conversation. Adam Rutherford talks to wildlife biologist Jonathan Slaght, novelist Juhea Kim and criminal psychologist Julia Shaw.

Jonathan Slaght discusses Tigers Between Empires, his account of the international effort to save the Siberian tiger from extinction in the wake of the Cold War.

Juhea Kim’s short story collection A Love Story from the End of the World imagines lives lived in precarious balance with nature, from biodomes in Seoul to landfill islands in the Pacific.

Dr Julia Shaw’s Green Crime investigates the psychology behind environmental destruction, profiling the perpetrators of ecological harm and the people fighting to stop them.
