Oceanic nations refer to the countries and territories located in the Pacific Ocean. This region includes a diverse range of islands and archipelagos, such as Australia, New Zealand, and the numerous islands of Polynesia, Micronesia, and Melanesia. These nations vary in size, culture, and population, with some being large landmasses while others are small, remote islands. Many Oceanic nations are known for their unique ecosystems and rich marine biodiversity. They often rely on the ocean for their livelihoods, including fishing and tourism. Additionally, these nations face challenges such as climate change and rising sea levels, which threaten their environments and communities.
