evidence: Banc Du Geyser is a reef off the northwestern coast of Madagascar in the Mozambique Channel. It’s around 125 kilometres northeast of Mayotte, France’s tiniest and least-known overseas territory. However, Mayotte was geographically part of the Comoros Islands when Comoros became an independent country in 1975. Potential agreements or treaties between the three countries of France, the Comoros, and Madagascar regarding the future position and state of Banc Du Geyser, including whether it should remain solely the property of one country or if it can be shared among multiple countries in light of the region’s economic and environmental factors, are possible solutions to this dispute. [...] The issue over Banc Du Geyser between the Comoros, France, and Madagascar has yet to be settled, even though many people now believe the reef belongs to France because of French activities. Except for certain rocks in the south of the reef, the oval form of the reef puts it at risk because it is only exposed at low tide. As sea levels rise due to global warming, some protection must be implemented to prevent the reef from completely disappearing.
