FAQs on Mind Map: Forest - Our Lifeline - Science Class 7 (Old NCERT)

1. What are the key benefits of forests for our environment?
Ans.Forests provide numerous benefits to the environment, including oxygen production through photosynthesis, carbon dioxide absorption, and habitat for a diverse range of species. They help maintain the water cycle, prevent soil erosion, and regulate temperature. Forests also contribute to biodiversity, which is crucial for ecosystem stability.
2. How do forests impact climate change?
Ans.Forests play a vital role in mitigating climate change by acting as carbon sinks. They absorb carbon dioxide from the atmosphere, thus reducing the greenhouse effect. Deforestation, on the other hand, releases stored carbon back into the atmosphere, contributing to global warming. Protecting and restoring forests is essential for climate change mitigation.
3. What are the threats faced by forests today?
Ans.Forests face several threats, including deforestation due to agriculture, logging, and urban development. Climate change also poses a significant risk, leading to forest degradation and increased susceptibility to pests and diseases. Other threats include wildfires and pollution, which can severely impact forest ecosystems.
4. How do forests contribute to human livelihoods?
Ans.Forests contribute to human livelihoods in various ways. They provide resources such as timber, medicinal plants, and food. Many communities rely on forests for their daily needs, including fuelwood and non-timber forest products. Additionally, forests offer recreational opportunities and promote ecotourism, which can enhance local economies.
5. What actions can be taken to protect and conserve forests?
Ans.To protect and conserve forests, individuals and communities can engage in sustainable practices such as reforestation, responsible logging, and supporting conservation policies. Raising awareness about the importance of forests and promoting sustainable land use can also help. Additionally, supporting organizations that work towards forest conservation can make a significant impact.
