A naturalist is a person who studies or has a deep interest in nature, particularly in the observation of plants, animals, and ecosystems. They often focus on understanding the relationships between different species and their environments. Naturalists can work in various fields, including biology, ecology, and conservation, and they may conduct research, lead educational programs, or engage in wildlife preservation efforts. Naturalists often use their skills to promote awareness about environmental issues and the importance of biodiversity. Famous naturalists like Charles Darwin and John Muir have made significant contributions to our understanding of the natural world, influencing both science and conservation practices.
