National parks are designed to protect areas of significance for which of the following purposes?

National parks are primarily established to safeguard natural landscapes, ecosystems, and biodiversity, promoting the understanding and appreciation of nature among the public. The integration of educational, recreational, and scientific use is critical to their purpose. National parks serve as living laboratories for scientific research, offering opportunities to study ecology, conservation, and environmental processes. They are also places where individuals and families can engage in recreational activities, such as hiking, camping, and wildlife observation, fostering a connection between people and the natural world.

The educational aspect is equally significant, as national parks often promote environmental awareness through programs, visitor centers, and guided tours. Through these initiatives, parks help disseminate knowledge about conservation efforts and environmental sustainability, encouraging visitors to value and protect natural resources.

In contrast, the other choices do not align with the fundamental purpose of national parks. While tourism can be a component of national parks to generate awareness and funding, commercial development, urban expansion, and agricultural development typically conflict with the conservation-focused mission of these protected areas.
