Conservation of Plants and Animals — Question 22
Back to all questionsQuestion 7
How can you contribute to the maintenance of green wealth of your locality? Make a list of actions to be taken by you.
We can contribute to the maintenance of green wealth of our locality by participating in following actions:
- Planting Trees — Participating in tree planting initiatives in our community in order to make our locality greener.
- Conserve Water — We can practice water conservation techniques such as fixing leaks, using water-efficient appliances, and collecting rainwater for irrigation to support healthy plant growth.
- Reduce, Reuse, Recycle — We can minimize waste generation by reducing consumption, reusing materials, and recycling whenever possible to lessen the burden on landfills and reduce environmental impact.
- Reduce Energy Consumption — Simple habit of switching off lights, fans and other appliances when not in use can help to conserve a lot of energy.
- Creating awareness — Educating and creating awareness regarding environment will help us to minimize environmental damage.
Chapter Overview: Conservation of Plants and Animals
This environmental chapter covers deforestation and its consequences, the importance of biodiversity, types of protected areas (biosphere reserves, national parks, wildlife sanctuaries), and concepts like endemic species, Red Data Book, and migration. Reforestation and paper recycling link conservation to everyday action.
Board Exam Weightage: 5-7 marks | Difficulty: Moderate
Key Formulas & Concepts
| Concept | Details |
|---|---|
| Biosphere Reserve | Large protected area: conservation + research + development (e.g., Pachmarhi, Sundarbans) |
| National Park | Strictly protected area: no human activity allowed (e.g., Jim Corbett, Kaziranga) |
| Wildlife Sanctuary | Animals protected, limited human activity like grazing allowed (e.g., Bharatpur, Periyar) |
| Red Data Book | Record of endangered species maintained by IUCN |
Must-Know Concepts
- Deforestation leads to soil erosion, desertification, floods, global warming, biodiversity loss
- India is one of 12 mega-biodiversity countries
- Endemic species are found only in a specific area; endangered species are at risk of extinction
- Reforestation = replanting where forest existed; Afforestation = planting where forest never was
- Siberian crane migrates from Siberia to Bharatpur (India) in winter
- Recycling 1 tonne of paper saves about 17 trees
Protected Areas Comparison
| Feature | Biosphere Reserve | National Park | Wildlife Sanctuary |
|---|---|---|---|
| Size | Largest | Medium | Smallest |
| Purpose | Conservation + Research + Development | Strict wildlife protection | Animal protection in natural habitat |
| Human Activity | Limited (buffer zone) | Not allowed | Limited (grazing allowed) |
| Example | Pachmarhi (MP), Nilgiri | Jim Corbett (UK), Gir (GJ) | Bharatpur (RJ), Periyar (KL) |
Common Mistakes to Avoid
- Confusing biosphere reserve, national park, and wildlife sanctuary
- Mixing up endemic (exclusive to area) and endangered (at risk of extinction)
- Confusing reforestation (re-planting) and afforestation (new planting)
- Thinking Red Data Book lists ALL species (only endangered ones)
Scoring Tips
- Make a comparison table of protected areas with examples for each
- Use memory aids: Endemic = Exclusive location; Endangered = at risk of Ending
- Memorise 5 national parks and 5 wildlife sanctuaries with states
- Practice drawing the cause-consequence chain of deforestation
