Zanzibar's white-sand beaches and turquoise reefs may look like paradise, but tourism here is a double-edged sword. Inland, spice plantations and coastal forests support endemic species like the red colobus monkey, yet along the coast, unchecked resort development and growing visitor pressure are straining fragile ecosystems.
Just off Zanzibar, Chumbe Island shows what careful stewardship can achieve. Its reefs are some of the healthiest in East Africa, home to over 500 species of fish, sea turtles, and bright corals. Inland, coastal forest shelters rare plants and birds, while an eco-lodge runs entirely on solar energy and rainwater.
