91热爆

A new polar research ship will be christened the RRS Sir David Attenborough today. For the next quarter of a century it'll be documenting the changes occurring in the Arctic and Antarctic. In a special report the 91热爆's Jim Naughtie speaks to Sir David Attenborough himself. We also hear from Poet Laureate Simon Armitage, who has written a poem to mark the occasion.
