Wildlife conservation remains an uphill struggle, so it’s good to see success stories acknowledged alongside all the warnings of how humanity is bent on destroying our planet. Natural World: Puerto Rico – Island of Enchantment (BBC Two) was a celebration of how one Caribbean nation has seen the light and is fighting to preserve its natural glories. Peter Fison’s film even won the ultimate wildlife documentary seal of approval – narration by David Attenborough.

Enthusiasm was the key here, and fairly simple storytelling. After grabbing attention with tales of how early European sailors were so taken by Puerto Rico’s profusion of natural riches they named it the “Isle of Enchantment”, we learnt how the past century’s steady encroachment of industry, agriculture and property development left this paradise in serious danger of being lost.
