The correct option for promoting biodiversity within an ecological management plan is
B. Establishing protected areas and wildlife corridors.
Detailed Explanation
-
Understanding Biodiversity: Biodiversity refers to the variety of life in a particular habitat or ecosystem. It includes the diversity of species, genetic diversity within species, and the variety of ecosystems. High biodiversity is crucial for ecosystem resilience, providing services such as pollination, nutrient cycling, and climate regulation.
-
Why Option B is Correct:
- Protected Areas: Establishing protected areas, such as national parks and reserves, helps conserve habitats and the species that live within them. These areas are often free from human exploitation, allowing ecosystems to function naturally and species to thrive.
-
Wildlife Corridors: Wildlife corridors are strips of natural habitat that connect isolated populations. They allow animals to migrate, find mates, and access resources, which is essential for maintaining genetic diversity and reducing the risks of inbreeding. Corridors also help species adapt to changing environmental conditions, such as climate change.
-
Why Other Options are Incorrect:
- Option A: Implementing monoculture farming practices: Monoculture involves growing a single crop over a large area. This practice reduces biodiversity because it eliminates the variety of plants and animals that would otherwise coexist in a more diverse ecosystem. Monocultures are also more susceptible to pests and diseases, which can lead to crop failures and further loss of biodiversity.
- Option C: Increasing urban development in natural habitats: Urban development typically leads to habitat destruction, fragmentation, and pollution, all of which negatively impact biodiversity. As natural habitats are converted into urban areas, many species lose their homes, leading to declines in populations and even extinction.
- Option D: Reducing government regulations on land use: Regulations are often put in place to protect natural habitats and biodiversity. Reducing these regulations can lead to over-exploitation of resources, habitat destruction, and increased pollution, all of which threaten biodiversity. Without regulations, there is a higher risk of unsustainable practices that can degrade ecosystems.
Summary of Key Points
- Biodiversity is essential for ecosystem health and resilience.
- Protected areas and wildlife corridors are effective strategies for conserving biodiversity.
- Monoculture farming and urban development harm biodiversity by destroying habitats.
- Reducing regulations can lead to unsustainable land use practices that threaten ecosystems.
Revision Summary
- Biodiversity includes species diversity, genetic diversity, and ecosystem variety.
- Protected areas and wildlife corridors are crucial for maintaining and promoting biodiversity.
- Monoculture farming and urban development negatively impact biodiversity.
- Government regulations help protect natural habitats and biodiversity.
