Coastal countries are nations that have coastlines along oceans, seas, or large lakes. These countries often benefit from access to marine resources, trade routes, and tourism opportunities. Examples of coastal countries include Australia, Brazil, and Japan, each with unique coastal ecosystems and cultures. The geography of coastal countries can vary widely, featuring sandy beaches, rocky cliffs, and estuaries. Many coastal areas are home to diverse wildlife and are important for fishing industries. Additionally, coastal countries may face challenges such as climate change, which can lead to rising sea levels and increased storm activity.
