Access NCERT Solutions for Class - 8 Science Chapter 7 – पौधों और जानवरों का संरक्षण

1. निम्नलिखित में अंतर स्पष्ट कीजिए-

वन्यप्राणी उद्यान एवं जेवमण्डलीय आरक्षित क्षेत्र

उत्तर:

(क) वन्यप्राणी अभ्यारण्य ऐसी जगह हैं जो केवल वन्य जंतुओं को सुरक्षा प्रदान करता है।

(ख) यहां प्राय हर लुप्तप्राय प्राणी को सुरक्षा दिया जाता है एवं अवैध शिकार, दरिंदगी तथा उनके वातावरण के साथ दख़ल अंदाजी को निषेध गया है।

(ग) यहां के रास्ते पर्यटकों रहता प्रयोगकेंद्रों के लिए खोले जा सकते हैं।

2. वनोन्मूलन का निम्न पर क्या प्रभाव पड़ता है, चर्चा कीजिए-

(क) वन्यप्राणी

उत्तर: वनोन्मूलन का सबसे ज़्यादा प्रभाव वन्य प्राणियों पर ही पड़ता है। हर एक प्राणी हर दूसरे प्राणी पर निर्भर करता है। और वानोन्मूलन की वजह से प्राणियों कि मृत्यु की संख्या बढ़ जाति है। उच्च स्तरीय अथवा ऊंच कोशिका तंत्र वाले प्राणी एवं निचले कोशिका तंत्र वाले प्राणी हमेशा एक

दूसरे पर निर्भर करते हैंए और वे सब पेड़ों और पोधों पर अपने भोजन और

जीवन जापान हेतु निर्भर करते हैं। और वनोन्मूलान इन्न सब प्राणियों के जीवन को नष्ट कर देता है।

(ख) पर्यावरण

उत्तर: वानोन्मूलान पर्यावरण पर भी भारी प्रभाव डालता है। पेड़ पौधों की कटाई की वजह से ज़मीन ढीली पड़ जाती है, तथा कार्बन डाइऑक्साइड कीमात्रा वायुमंडल में बढ़ने लगती है, जिसकी ग्रीनहाउस गैसों का उत्सर्जन होता है। । मिट्टी की जलाधरण क्षमता घटने लगती है, जिसके कारण बाढ़ का ख़तरा बढ़ जाता है। परिणामस्वरूप सारे वन्य में मृदा के अन्य गुण जेसे पोषक तत्वों, गठन इत्यादि प्रभावित होते हैं।

(ग) अगली पीढ़ी

उत्तर: वनोनमूलन की वजह से हमारे आनेवाले पीढ़ी पर बेहद बुरा असर पड़ेंगे। ऑक्सीजन की मात्रा कम होने लगेंगी एवं ग्रीनहाउस गैसों का कब्जा पड़ जाएगा वायुमंडल पर। परिणामस्वरूप वैश्विक तापमान और गर्माहट बढ़ जाएगी और खानपान के उपलब्धता में अव्यवस्था आने लगेंगी। उपजाऊ ज़मीन की की तलाशी में ज़िन्दगी कर जाएगी और, दूसरी तरफ, हिमनद के तरालने से बाढ़ आने की संभावना बढ़ जाएंगी। इंसानों की ज़िन्दगी को भी ख़तरा पड़ जाएगा, और उन्हें बचाने के लिए कोई नहीं रहेगा।

3. संरक्षित वन भी वन्य जंतुओं के लिए पूर्ण रूप से सुरक्षित नहीं, क्यों?

उत्तर:सुरक्षित वन वह हैं जिनको लुप्तप्राय प्रजातियों तथा अन्य प्राणियों की सुरक्षा के लिए बनाई गई, उनको विलुप्त होने से बचाने के लिए। वनों के आसपास आदिवासियों का बसेरा होता है, और अक्सर वही लोग सुरक्षा सीमा की उलंघन करते हुए वनों में घुस जाते है, एवं अपने मतलब के लिए मनचाहे पेड़ पोधो और प्राणियों कि विनाश में लग जाते हैं। उनके फल, फूल, लकड़ी तथा मांश, चमड़ी और हड्डियों की संग्रह की जाती है जो बाजारों में अच्छे कीमतों में बिकते हैं। कुछ इलाकों की आदिवासी उतने हानिकारक होते हैं कि बाहरी इलाकों के लोगों के लिए बाधी बन जाते हैं, एवं इंसानों के लिए व संकट बन जाते हैं। उन जगहों को श्रेणियों में बांटा गया है, जहां सबसे भीतर वाले श्रेणियों में किसी भी इंसान का जाना है, तथा सबसे बाहर वाले हिस्सों में पर्यटकों को आने में कोई लांछन नहीं लगाई जाती। ऐसे हालात में सुरक्षित बन के होते हुए भी ख़तरा बढ़ जाता है।
