Born on fire, held by water. International Day of the Tropics
Observed each 29 June, the International Day of the Tropics spotlights a vast region stretching between the Tropics of Cancer and Capricorn, where warmth and rainfall shape daily life. This zone covers about 40% of Earth's surface area, yet supports around 80% of global biodiversity, making it central to planetary health and culture.
In French Polynesia, Bora Bora offers a clear snapshot of that complexity. The island is the eroded core of an ancient volcano, its dark basalt peaks—Mount Otemanu and Mount Pahia—rising from shallow turquoise waters. Around it, a barrier reef encloses calm water, forming a lagoon as volcanic rock slowly subsides and the reef grows upwards. Locally called Pora Pora in Tahitian, meaning 'firstborn,' the island reflects both geological time and living culture, where language, ocean systems and landforms remain closely linked.
