Natural reserves are protected areas of land or water that are set aside to conserve wildlife and their habitats. These areas help preserve biodiversity, which is the variety of life on Earth, including plants, animals, and ecosystems. By safeguarding these environments, natural reserves play a crucial role in maintaining ecological balance and providing a safe haven for endangered species like the California condor or the Amur leopard. In addition to protecting wildlife, natural reserves offer opportunities for research, education, and recreation. They allow people to connect with nature through activities like hiking, birdwatching, and photography. By visiting these areas, individuals can learn about the importance of conservation and the need to protect our planet's precious resources.
