One of the grandchildren of polar explorer Captain Robert Scott has marked the 100th anniversary of his death by launching an appeal which aims to inspire future generations.
As he lay dying in his tent in March 1912, Captain Scott wrote his last letter to his wife.
Some of his thoughts were for his son, as he penned the words "make the boy interested in natural history if you can".
That boy, Peter, grew up to be regarded as the father of modern conservation.
And today, his legacy was honoured at the London Wetlands Centre in Barnes.
