FAQs on Biodiversity and Conservation - Introduction Video Lecture - Geography Class 11 - Humanities/Arts

1. What is biodiversity and why is it important?
Ans. Biodiversity refers to the variety of life on Earth, including the different species, ecosystems, and genetic diversity. It is important because it provides essential ecosystem services such as clean air and water, soil fertility, and climate regulation. Biodiversity also plays a crucial role in maintaining the balance of ecosystems and promoting resilience against environmental changes.
2. How does human activity impact biodiversity?
Ans. Human activities such as deforestation, habitat destruction, pollution, overexploitation of resources, and climate change have significant impacts on biodiversity. These activities can lead to the loss of species, destruction of habitats, and disruption of ecosystems. Human-induced changes in biodiversity can have cascading effects on the functioning of ecosystems and can ultimately threaten our own well-being.
3. What is conservation and why is it important for biodiversity?
Ans. Conservation refers to the protection, management, and restoration of the natural environment and wildlife. It is important for biodiversity because it helps in preserving the variety of species, ecosystems, and genetic diversity on Earth. Conservation efforts aim to prevent the extinction of species, maintain ecological balance, and sustain ecosystem services for the benefit of present and future generations.
4. What are some strategies for conserving biodiversity?
Ans. Strategies for conserving biodiversity include the establishment of protected areas such as national parks and reserves, sustainable management of natural resources, habitat restoration and creation, promoting sustainable practices in agriculture and forestry, raising awareness and education, and implementing policies and legislation for conservation. Collaboration between governments, organizations, and individuals is crucial for the effective conservation of biodiversity.
5. How can individuals contribute to biodiversity conservation?
Ans. Individuals can contribute to biodiversity conservation in various ways. Some actions include reducing their ecological footprint by practicing sustainable consumption and lifestyles, supporting local and organic food production, planting native species in gardens, conserving water and energy, volunteering for conservation organizations, and advocating for biodiversity protection through awareness campaigns and supporting policies that prioritize conservation efforts.
