World Ozone Day 16 SEP 2021

"World Ozone Day:2021 The slogan of the day, ‘Keeping us, our food and vaccines cool.'’, reminds us that not only is ozone crucial for life on Earth but that we must continue to protect the ozone layer for future generations."

World Ozone Day is observed on September 16, every year. It is celebrated to spread awareness among people about the depletion of the Ozone Layer and search for possible solutions to preserve it. On this day, people from all over the world are expected to join the Montreal protocol to join the talks and seminars. A number of commonly used chemicals have been found to be extremely damaging to the ozone layer.

Life on Earth would not be possible without sunlight. But the energy emanating from the sun would be too much for life on Earth to thrive were it not for the ozone layer. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation.

The Ozone layer or also known as the Ozone shield, a delicate layer of gas, in the Earth’s stratosphere absorbs most of the Sun’s ultraviolet rays. These rays can cause numerous skin diseases.

World Ozone Day: History

On December 19, 1994, the United Nations General Assembly proclaimed September 16 the International Day for the Preservation of the Ozone Layer, commemorating the date, in 1987, on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed.

On September 16, 1987, the United Nations and 45 other countries signed the Montreal Protocol, on substances that deplete the Ozone layer. Every year, this day is celebrated as the International Day for the Preservation of the Ozone layer.

The purpose of the Montreal Protocol is to protect the Ozone layer by reducing the production of substances that are supposed to be responsible for Ozone layer depletion.

This year, we celebrate 36 years of the Vienna Convention and 35 years of global ozone layer protection.

The Ozone layer is a piece of the atmosphere that has high ozone concentrations. Ozone is a gas that is made of three oxygen atoms O3. Depending on where the ozone layer is, it can either harm life or protect life on Earth.

Most of the ozone stays within the stratosphere whereby it acts as a shield, protecting the surface of the Earth from the harmful ultraviolet radiation of the sun. If this shield was to weaken, we would all be more susceptible to impaired immune systems, cataracts, and skin cancer.

हिंदी दिवस 14 सितंबर

 हिंदी दिवस 14 सितंबर 

हर साल हिंदी दिवस 14 सितंबर को मनाया जाता है। इस दिन ही देवनागरी लिपि में
हिंदी को भारत की आधिकारिक भाषा के रूप में अपनाया गया था। साल 1953
में पहली बार हिंदी दिवस का आयोजन हुआ था।

तभी से यह सिलसिला बना हुआ है। हिंदी दिवस को मनाने का उद्देश्य हिंदी
भाषा की स्थिति और विकास पर मंथन को ध्यान में रखना है। देश में करीब 77 प्रतिशत से
भी ज्यादा लोग हिंदी बोलते हैं।

भारत की मुख्य भाषा हिंदी को कब मिली पहचान-

14 सितंबर 1949 को व्यौहार राजेंद्र सिम्हा के 50 वें जन्मदिन पर हिंदी को आधिकारिक भाषा (Official Language) के रूप में अपनाया गया और इसके बाद
प्रचार-प्रसार को आगे बढ़ाने के प्रयासों में तेजी आई. भारत के संविधान द्वारा 26 जनवरी 1950 को
यह निर्णय लागू किया गया था 
भारतीय संविधान के अनुच्छेद 343 (Article 343) के तहत देवनागरी लिपि (Devanagari Script) में
लिखी गई हिंदी (120 से अधिक भाषाओं में प्रयुक्त होने वाली लिपि) को आधिकारिक भाषा के रूप में अपनाया गया था . 

सरकारी कार्यालयों और शिक्षण संस्थानों में 15 दिन तक हिंदी पखवाड़ा मनाया जाता है।
14 सितंबर 1949 को संविधान सभा की ओर से हिंदी को आजाद भारत की मुख्य भाषा का
दर्जा प्राप्त हुआ था। इसका उल्लेख संविधान के अनुच्छेद 343 (1) में किया गया है। अनुच्छेद के
अनुसार भारत की राजभाषा ‘हिंदी’ और लिपि ‘देवनागरी’ है।

क्यों मनाया जाता है हिंदी दिवस-

हिंदी दिवस के मौके पर देशभर के स्कूलों, कॉलेज और शैक्षणिक संस्थानों में कई तरह की प्रतियोगिताओं का आयोजन किया जाता है। हिंदी पूरे विश्व में चौथी सबसे ज्यादा बोली जाने
वाली भाषा है। वहीं दूसरी ओर भारत में अन्य कई भाषाएं विलुप्त हो रही हैं। जो चिंतन का विषय है।
ऐसे में हिंदी की महत्ता बताने और प्रचार-प्रसार के लिए हिंदी दिवस को मनाया जाता है।

गृह मंत्रालय ने 25 मार्च 2015 के अपने आदेश में हिंदी दिवस पर प्रतिवर्ष दिए जाने वाले दो पुरस्कारों
के नाम बदल दिए थे. 1986 में स्थापित इंदिरा गांधी राजभाषा पुरस्कार को बदलकर राजभाषा कीर्ति
पुरस्कार’ और राजीव गांधी राष्ट्रीय ज्ञान-विज्ञान मौलिक लेखन पुरस्कार को बदलकर राजभाषा गौरव
पुरस्कार कर दिया गया था.
