The coastal region refers to the areas where land meets the ocean or sea. These regions are characterized by unique ecosystems, including beaches, cliffs, and wetlands. Coastal areas often support diverse wildlife and are important for fishing, tourism, and recreation. They can also be vulnerable to natural events like storms and rising sea levels. Coastal regions are found all over the world, from the Gulf of Mexico in North America to the Great Barrier Reef in Australia. Many cities, such as Los Angeles and Rio de Janeiro, are located in these areas, benefiting from their scenic views and economic opportunities.
