Biodiversity preservation refers to the protection and maintenance of the variety of life on Earth, including different species of plants, animals, and microorganisms. This diversity is crucial for ecosystem health, providing essential services such as clean air, water, and food. Efforts to preserve biodiversity often involve creating protected areas, restoring habitats, and implementing sustainable practices. Conservation strategies may also include laws and regulations to prevent overexploitation of resources and protect endangered species like the California condor or Sumatran tiger. Public awareness and education about the importance of biodiversity are vital for encouraging community involvement in preservation efforts.
