Coastal zones are areas where land meets the ocean or sea. These regions are characterized by unique ecosystems that include beaches, wetlands, and estuaries. Coastal zones are important for biodiversity, providing habitats for various species of plants and animals, including marine life and shorebirds. Human activities, such as fishing, tourism, and urban development, often take place in coastal zones, making them vital for economies. However, these areas are also vulnerable to environmental issues like erosion, pollution, and the impacts of climate change, which can threaten both natural habitats and human communities.
