Marine parks are protected areas in oceans and seas designed to conserve marine life and habitats. They help preserve biodiversity by providing safe environments for various species, including fish, corals, and marine mammals. These parks often restrict activities like fishing and pollution to maintain healthy ecosystems. Visitors to marine parks can enjoy activities such as snorkeling and diving, which allow them to observe the beauty of underwater life. Many marine parks also focus on education and research, helping people understand the importance of protecting our oceans and the role of marine conservation in sustaining marine ecosystems.
