प्रश्न १: प्रकृति में आए असंतुलन का क्या परिणाम हुआ?

उत्तर : प्रकृति में आए असंतुलन का यह परिणाम हुआ कि कोई भी प्रदूषण के प्रभाव से अछूता नहीं रहा | पक्षियों ने बस्तियों से भागना शुरू कर दिया | गर्मियों में ज़्यादा गर्मी, बेवक्त की बरसातें, भूकंप, सैलाब, तूफ़ान, ज़लज़ले और नित नए रोगों के रूप में हम इस असंतुलन के प्रभाव को स्पष्ट देख सकते हैं | प्रकृति की सहनशक्ति की एक सीमा होती है और जब उसके साथ अत्यधिक छेड़छाड़ की जाती है, तो प्रकृति में असंतुलन पड़ जाता है | इससे पर्यावरण पर बुरा प्रभाव पड़ता है |
