In this special edition of Witness History to mark COP26, 主播大秀 Environment correspondent Claire Marshall brings us five important moments in environmental history.

We hear from the women who fought to free their families from homes built on 20,000 tonnes of toxic waste. We travel to Kenya's Karura Forest to speak to the daughter of Wangari Maathai, the first African woman to win the Nobel Peace prize. Maathai dedicated much of her life trying to protect Kenya's forests. And we hear from 'the man who fed the world', as crop pioneer Norman Borlaug was dubbed. His 'green revolution' helped combat famine and malnutrition and enabled countries like India to become self-sufficient.

We also find out how Saddam Hussein ordered a huge engineering project to drain the largest wetland in the Middle East. And finally, we look back at the fight to ban lead in petrol in the United Kingdom, a move that followed a successful campaign showing that lead was poisoning children and leaving them permanently brain damaged.
