Important Questions on Class 6 Science Chapter 16

Which kind of garbage is not converted into compost by the redworms?
Non bio-degradable waste like pieces of synthetic cloth, polythene bags, broken glass, aluminium wrappers, nails and broken toys cannot be converted into compost by the redworms.
क्या आपने अपने कंपोस्ट-गड्ढे में लाल केंचुओं के अतिरिक्त किसी अन्य जीव को भी देखा है? यदि हाँ, तो उसका नाम जानने का प्रयास कीजिए।
लाल केंचुओं के अलावा मकड़ियों, छोटे कीड़े, मक्खियों और बड़े कीड़े आदि को गड्ढे में देखा जा सकता है। खाद भी रोगाणुओं से समृद्ध होती है जिसे बिना आंखों के नहीं देखा जा सकता है।
क्या कचरे का निपटान केवल सरकार का ही उत्तरदायित्व है?
कचरा निपटान न केवल सरकार का उत्तरदायित्व है बल्कि प्रत्येक नागरिक की जिम्मेदारी है। अगर हम इतना कचरा पैदा करते रहेंगे तो बड़े पैमाने पर बीमारियां बढ़ेंगी। प्लास्टिक, पॉलीबैग जैसे गैर-बायोडिग्रेडेबल अपशिष्ट भी पर्यावरण के लिए हानिकारक कारकों को जोड़ते हैं। हमें कचरे के उत्पादन को कम करने के तरीकों को सुनिश्चित करना चाहिए। जहां भी संभव हो, हमें अपने दैनिक उपयोग में पुनरावर्तनीय सामग्री का उपयोग करना चाहिए।
Is it possible to reduce the problems relating to disposal of garbage?
Yes it is possible to reduce the problems relating to disposal of garbage to a large extent. We should use those materials which are recyclable and avoid or reduce the use of non-biodegradable materials. While throwing out garbage in trash can, we should separate biodegradable waste from non-biodegradable and throw them in separate bins.
What do you do with the leftover food at home?
We use to feed animals (roaming on the road or in street) with leftover food.
If you and your friends are given the choice of eating in a plastic plate or a banana leaf platter at a party, which one would you prefer and why?
Banana leaf is a better choice. It is bio-degradable and can be disposed easily. On the other hand, eating in plastic plate is not good as plastic is non-biodegradable, it will not dispose-off easily.
एक ऐसा उदाहरण दीजिए जिसमें पैकेजिंग की मात्रा कम की जा सकती थी।
पैकेजिंग सामग्री का पुन: उपयोग करके, हम पैकेजिंग सामग्री को कम कर सकते हैं।
पैकेजिंग से कचरे की मात्रा किस प्रकार बढ़ जाती है, इस विषय पर एक कहानी लिखिए।
पैकेजिंग का मूल उद्देश्य उत्पाद को छेड़छाड़ से बचाना और उसकी ताजगी बनाए रखना है। हालांकि, अधिकांश पैकेजिंग सामग्री का उपयोग उत्पाद को सुंदर बनाने तथा आकर्षक दिखने के लिए किया जाता है। दुर्भाग्य से पैकेजिंग सामग्री का एक बड़ा हिस्सा बेकार चला जाता है और कूड़ेदान में फेंक दिया जाता है। उदाहरण के लिए, अधिकांश स्थानों पर कचरे के डिब्बे चिप्स, बिस्कुट, आदि के कूड़े से भरे हुए हैं। यह अनावश्यक रूप से कचरे की मात्रा को बढ़ाता है। यह अनावश्यक पैकेजिंग के कारण उत्पाद की लागत में भी वृद्धि करता है। हमें गंभीरता से विचार करना चाहिए कि अनावश्यक पैकेजिंग को कैसे कम किया जाए।
Do you think it is better to use compost instead of chemical fertilisers? Why?
No doubt compost is better to use than chemical fertilizers due to following reasons:
Compost is much easier to prepare.
Compost is environment friendly whereas fertilizers can harm our health and the environment.
Compost does not pollute our environment.
Compost decomposes bio-degradable waste into natural soil. It conserves our environment.
