Island countries are nations that are primarily located on islands or consist of multiple islands. These countries can be found in various oceans and seas around the world, and they often have unique ecosystems and cultures due to their geographical isolation. Examples of island countries include Japan, Australia, and Madagascar. Many island countries rely heavily on tourism, fishing, and agriculture for their economies. Their natural beauty, including beaches and coral reefs, attracts visitors from around the globe. Additionally, island nations often face challenges such as climate change, which can lead to rising sea levels and extreme weather events, threatening their habitats and livelihoods.
