FAQs on Loss of Biodiversity Video Lecture - Biology Class 12 - NEET

1. What is biodiversity loss?
Ans. Biodiversity loss refers to the decline in the variety and abundance of different species in a particular ecosystem or on a global scale. It occurs when species become extinct, their populations decrease significantly, or their habitats are destroyed or degraded.
2. What are the main causes of biodiversity loss?
Ans. The main causes of biodiversity loss include habitat destruction and fragmentation, pollution, climate change, invasive species, and overexploitation of natural resources. These factors often interact and exacerbate the loss of biodiversity.
3. How does biodiversity loss affect ecosystems and the environment?
Ans. Biodiversity loss has significant impacts on ecosystems and the environment. It disrupts the delicate balance of ecological interactions, leading to the loss of important ecosystem services such as pollination, nutrient cycling, and pest control. It also weakens the resilience of ecosystems to adapt to environmental changes, making them more vulnerable to disturbances.
4. What are the consequences of biodiversity loss for humans?
Ans. Biodiversity loss can have severe consequences for humans. It affects food security, as many crops depend on pollinators and healthy ecosystems for their growth. It also impacts the availability of clean water, as intact ecosystems play a crucial role in regulating water quality and quantity. Additionally, the loss of biodiversity can lead to the emergence of zoonotic diseases and the loss of potential sources for new medicines and genetic resources.
5. How can we address or mitigate biodiversity loss?
Ans. Addressing biodiversity loss requires a combination of conservation efforts and sustainable practices. This includes protecting and restoring habitats, implementing effective management strategies for protected areas, reducing pollution and greenhouse gas emissions, promoting sustainable agriculture and fisheries, and raising awareness about the importance of biodiversity conservation. Collaboration between governments, organizations, and individuals is essential to achieve meaningful results in mitigating biodiversity loss.
