The entire population of the earth could easily become seasteaders, and not even leave shallow tropical waters.
The Tuamotus Archipelago, part of French Polynesia, covers a surface area the size of Western Europe. Yet land area is only 328 square miles hosting a population of about 18,000 people.
Similarly, the Mascarene Plateau is a submarine plateau in the Indian Ocean, north and east of Madagascar. The plateau extends approximately 2,000 km (1,200 mi), from the Seychelles in the north to Réunion in the south. The plateau covers an area of over 115,000 km2 (44,000 sq mi) of shallow water, with depths ranging from 8–150 m (30–490 ft), plunging to 4,000 m (13,000 ft) to the abyssal plain at its edges.
