FAQs on Biodiversity - Environment & Ecology - UPSC Video Lecture - Environment for UPSC CSE
| 1. What is biodiversity and why is it important for the environment? |  |
Ans. Biodiversity refers to the variety of living organisms found in a particular habitat or ecosystem. It encompasses the diversity of species, genes, and ecosystems. Biodiversity is crucial for the environment as it plays a vital role in maintaining the balance of ecosystems, providing ecosystem services such as pollination, nutrient cycling, and water purification. It also contributes to the resilience of ecosystems in the face of environmental changes.
| 2. How does biodiversity loss impact the environment and human society? | |
Ans. Biodiversity loss has severe repercussions for both the environment and human society. It disrupts ecosystems, leading to the loss of important ecological functions and services. This can result in decreased crop yields, increased vulnerability to pests and diseases, and reduced availability of clean water. Biodiversity loss also impacts cultural and economic aspects, such as the loss of traditional knowledge, impacts on tourism, and potential loss of potential sources for new medicines.
| 3. What are the main drivers of biodiversity loss? | |
Ans. Biodiversity loss is primarily driven by human activities. Some of the main drivers include habitat destruction and fragmentation, pollution, invasive species, overexploitation of natural resources, and climate change. These activities result in the degradation and destruction of habitats, leading to the loss of species and disruption of ecosystems.
| 4. How can we conserve biodiversity? | |
Ans. Conservation of biodiversity requires a multi-faceted approach. It involves protecting and managing habitats, establishing protected areas, implementing sustainable land-use practices, promoting the sustainable use of natural resources, and controlling invasive species. Additionally, raising awareness about the importance of biodiversity and engaging local communities in conservation efforts are crucial. International cooperation and policies are also necessary to address global biodiversity conservation challenges.
| 5. What are some examples of successful biodiversity conservation initiatives? | |
Ans. There have been numerous successful biodiversity conservation initiatives around the world. For example, the establishment of national parks and protected areas has helped in safeguarding diverse ecosystems and their species. Conservation programs focusing on endangered species like the conservation of giant pandas in China or the recovery of the black-footed ferret in North America have shown positive results. Additionally, community-based conservation projects, such as the establishment of community-managed forests, have proven to be effective in protecting biodiversity while supporting local livelihoods.
