The BBC has reported concerns over the preservation of Robben Island, South Africa's notorious former island prison. The island, where Nelson Mandela was held for the majority of his 27 years behind bars, is now a World Heritage site and tourist destination. However, feral rabbits are both threatening the local wildlife and undermining historic buildings. The City of Cape Town and the Western Cape provincial government said that if poor management of the island continued, it risked losing its World Heritage status.
