Naturalists are individuals who study and observe the natural world, focusing on plants, animals, and ecosystems. They often conduct field research, documenting their findings to better understand biodiversity and the relationships between different species. Naturalists may work in various settings, including national parks, wildlife reserves, and research institutions. Many naturalists are also passionate about conservation, advocating for the protection of habitats and endangered species. They may engage in educational outreach, sharing their knowledge with the public to promote awareness of environmental issues. Notable naturalists include Charles Darwin and John Muir, who made significant contributions to our understanding of nature.
