In 1995, as one of the Ogoni Nine, he was hanged after protesting against Shell’s oil pollution. With education and a move towards renewable energy, we can honour his legacy

Earlier this year, my father, Ken Saro-Wiwa, and his eight colleagues, known collectively as the Ogoni Nine, were pardoned for a crime they never committed. After peacefully campaigning against environmental degradation of Ogoniland in Nigeria at the hands of the oil industry, they were imprisoned by the military dictatorship on false charges of treason and incitement to murder, following a trial condemned by the international community as a sham.

On 10 November 1995, the men were executed by hanging.
