Which of the following statements about protected areas established to preserve biodiversity is true? (A) About 25% of Earth's land area is now protected. (B) National parks are the only type of protected area. (C) Management of a protected area does not need to be coordinated with management of the surrounding area. (D) It is especially important to protect biodiversity hot spots

Verified step by step guidance

1. Identify the key terms: Protected areas are regions designated for the preservation of natural resources, including biodiversity. Biodiversity hot spots are areas with a high number of endemic species that are under significant threat from humans.
2. Evaluate statement (A): Research current statistics on the percentage of Earth's land that is protected. As of recent data, less than 25% of Earth's land area is protected, making statement (A) incorrect.
3. Evaluate statement (B): Understand that protected areas include more than just national parks. They also encompass nature reserves, conservation areas, and other designated regions, making statement (B) incorrect.
4. Evaluate statement (C): Recognize that the management of protected areas often involves coordination with the surrounding areas to effectively preserve biodiversity, making statement (C) incorrect.
5. Evaluate statement (D): Acknowledge that biodiversity hot spots, due to their richness and vulnerability, are critical areas to protect. Protecting these areas helps preserve a significant number of species, making statement (D) true.

Key Concepts

Biodiversity and Protected Areas

Biodiversity refers to the variety of life on Earth, encompassing different species, ecosystems, and genetic diversity. Protected areas are designated regions aimed at conserving this biodiversity by limiting human activities that can lead to habitat destruction and species extinction. These areas can include national parks, wildlife reserves, and marine protected areas, each serving a critical role in maintaining ecological balance.

Types of Protected Areas

Protected areas come in various forms, including national parks, wildlife sanctuaries, nature reserves, and marine protected areas. While national parks are well-known, they are not the only type of protected area. Each type has specific regulations and management practices tailored to the unique ecological and cultural values they aim to preserve.

Biodiversity Hotspots

Biodiversity hotspots are regions that are both rich in endemic species and significantly threatened by human activities. Protecting these areas is crucial because they contain a high number of species that are not found anywhere else, making their conservation vital for global biodiversity. Effective management of these hotspots often requires coordinated efforts that extend beyond the protected area to include surrounding landscapes.
