Human metabolism alone produces 2 billion tonnes of CO2 a year, study estimates

مطالعے کے مطابق انسانی جسم کی سرگرمی سے سالانہ 2 ارب ٹن کاربن ڈائی آکسائیڈ پیدا ہوتی ہے

अध्ययन के अनुसार मानव चयापचय से ही सालाना 2 अरब टन CO2 निकलता है

Human metabolism alone produces 2 billion tonnes of CO2 a year, study estimates

Key points

اہم نکات

मुख्य बातें

  • A global study estimates that human metabolism itself produces about 2 billion metric tonnes of carbon dioxide a year, simply from people breathing and living.
  • The figure is separate from emissions from cars, factories and power plants, and it shows how large the human footprint is even before fossil fuels are counted.
  • Researchers say the finding puts the scale of human activity in perspective, though breathing itself is part of the natural carbon cycle rather than the main driver of climate change.
  • ایک عالمی مطالعے کے مطابق صرف انسانی جسم کی سرگرمی اور سانس لینے سے سالانہ تقریباً 2 ارب میٹرک ٹن کاربن ڈائی آکسائیڈ پیدا ہوتی ہے۔ یہ تعداد گاڑیوں، کارخانوں اور بجلی گھروں کی آلودگی سے الگ ہے، اور یہ بتاتی ہے کہ انسانی سرگرمی کا حجم کتنا بڑا ہے۔ محققین کا کہنا ہے کہ یہ نتیجہ انسانی سرگرمی کے پیمانے کو سمجھنے میں مدد دیتا ہے، اگرچہ سانس لینا قدرتی کاربن چکر کا حصہ ہے، موسمیاتی تبدیلی کی اصل وجہ نہیں۔
  • एक वैश्विक अध्ययन के अनुसार केवल मानव शरीर की गतिविधि और सांस लेने से सालाना लगभग 2 अरब मीट्रिक टन कार्बन डाइऑक्साइड निकलता है। यह आंकड़ा गाड़ियों, कारखानों और बिजली संयंत्रों के उत्सर्जन से अलग है, और यह बताता है कि मानव गतिविधि का पैमाना कितना बड़ा है। शोधकर्ताओं का कहना है कि यह निष्कर्ष मानव गतिविधि के पैमाने को समझने में मदद देता है, हालांकि सांस लेना प्राकृतिक कार्बन चक्र का हिस्सा है, जलवायु परिवर्तन का मुख्य कारण नहीं।
