FAQs on Mindmap: Forest - Our Lifeline - Science Class 7

1. What is the importance of forests in our lives?
Ans. Forests play a vital role in our lives as they provide us with numerous benefits. They are the primary source of oxygen, help in regulating the climate, support biodiversity, provide livelihoods for communities, and offer recreational opportunities.
2. How do forests contribute to the regulation of the climate?
Ans. Forests help in regulating the climate through a process called carbon sequestration. They absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass. This helps in reducing the concentration of greenhouse gases, which in turn mitigates climate change.
3. What is the impact of deforestation on our lifeline?
Ans. Deforestation poses a significant threat to our lifeline as it leads to the loss of forest cover. This results in decreased oxygen production, increased carbon dioxide emissions, habitat destruction, soil erosion, and disruption of the water cycle. All these factors have adverse effects on our environment and overall well-being.
4. How can forests support biodiversity?
Ans. Forests are home to a wide range of plant and animal species, making them hotspots of biodiversity. They provide habitats and food sources for numerous organisms, including endangered species. By conserving forests, we can protect biodiversity and ensure the survival of various ecosystems.
5. What are some ways to protect and conserve forests?
Ans. There are several ways to protect and conserve forests. These include promoting sustainable logging practices, implementing reforestation programs, raising awareness about the importance of forests, supporting local communities in sustainable forest management, and enforcing laws against illegal logging and deforestation.
