(FILES) A general view of "Boca do Inferno£ (Hell's Mouth) beach near Sao Tome, capital of Sao Tome and Principe, on August 9, 2026. On the paradise island of Principe, a lush jungle haven in the turquoise waters of the Gulf of Guinea, a South African multimillionaire is offering locals a financial dividend to preserve the natural beauty on which his luxury tourism business depends. The initiative is the brainchild of tech entrepreneur Mark Shuttleworth, who for over a decade has been promoting a model of exclusive ecotourism aimed at an ultra-wealthy foreign clientele.
