Black carbon, the fine particulate matter born from distant industrial activities and unchecked emissions, is making its presence felt, leaving an indelible mark on the majestic peaks…

प्रकाश प्रदूषणले रातको आकाशलाई उज्यालो बनाउने र प्राकृतिक अन्धकारमा हस्तक्षेप गर्ने मानव गतिविधिहरूद्वारा उत्पादित अत्यधिक वा गलत दिशानिर्देशित कृत्रिम प्रकाशलाई जनाउँछ। यो सहरी र उपनगरीय क्षेत्रहरूमा कृत्रिम प्रकाशको अत्यधिक मात्राको कारणले गर्दा हुन्छ । जसले गर्दा वायुमण्डलमा प्रकाश छरिन्छ र रातको आकाशमा चमक सिर्जना गर्दछ। नेपालमा प्रकाश प्रदूषणले वातावरण र मानव समाज दुवैमा धेरै असर पारेको देखिन्छ । केहि प्रभावहरू…
