Coastal regions are areas where land meets the ocean or sea. These regions are characterized by unique ecosystems, including beaches, cliffs, and wetlands. They often support diverse wildlife and plant species, making them important for biodiversity. Coastal areas are also popular for recreational activities like swimming, fishing, and boating. Many coastal regions are economically significant due to tourism and fishing industries. Cities such as Miami and San Francisco thrive on their coastal locations, attracting visitors and providing jobs. Additionally, coastal areas are vulnerable to environmental issues like erosion and rising sea levels, which can impact both ecosystems and human communities.
