Conservation protects and manages natural resources and biodiversity. It includes setting aside national parks, restoring wetlands, protecting endangered species, and managing forests for long-term health. The field has roots in the 19th century, when hunters and naturalists grew alarmed at the disappearance of wildlife in North America and Europe. Yellowstone became the world's first national park in 1872. Since then, conservation has expanded from preserving scenic landscapes to addressing climate change, habitat fragmentation, and the rights of Indigenous peoples who live in and manage many of the world's remaining wild areas.

Conservation takes many forms. Protected areas keep development out. Restoration projects bring back degraded ecosystems. Laws regulate hunting, fishing, logging, and pollution. Community-based conservation involves local people in managing the resources they depend on. Each approach has trade-offs. Strict protection can displace communities. Sustainable use can fail if oversight is weak. The most effective projects often combine scientific monitoring with local knowledge and clear legal frameworks.

Common strategies

• Protected areas and wildlife corridors.
• Habitat restoration and reforestation.
• Species recovery programs.
• Community-based natural resource management.

Conservation is not about locking nature away. It is about keeping ecosystems functioning while people live and work within them.
