Judging by Radical Nature: Art and Architecture for a Changing Planet 1969-2009 (Barbican, now until 18th October 2009), Nature (with a capital N) is in crisis. It’s not just the familiar ecological message of the show – that the planet is fragile and we’re not helping matters – but something more unsettling, almost uncanny. It feels like Nature is shrinking.
