Why do islands have so many coconut trees on them?

Islands often have many coconut trees because these palms thrive in coastal environments and sandy soils typical of tropical regions. Coconuts can float and travel long distances on ocean currents, allowing them to colonize isolated islands. Additionally, their ability to tolerate saltwater and withstand harsh winds makes them well-suited for island ecosystems. The trees also provide food, shelter, and materials for island inhabitants, further promoting their growth.
