World Ozone Day 2023

World Ozone Day 2023

But, as we mark the UN's International Day for the Preservation of the Ozone Layer tomorrow (16 September), we can't afford to be complacent – the 'hole' discovered in the ozone layer above the Antarctic during the 1980s is still there and challenges, both old and new, continue to threaten the recovery of our planet's invisible shield against ultraviolet (UV) rays.

ಸೆಪ್ಟೆಂಬರ್ 16-ವಿಶ್ವ ಓಝೋನ್ ಪದರ ರಕ್ಷಣಾ ದಿನ ವಿಶ್ವ ಓಝೋನ್ ದಿನ (World Ozone Layer Protection Day)

ಓಝೋನ್ ಪರದೆಯು ಸೂರ್ಯನ ಅಪಾಯಕಾರಿ ಕಿರಣಗಳನ್ನು ನೇರವಾಗಿ ಭೂಮಿಗೆ ಬೀಳದಂತೆ ನೋಡಿಕೊಳ್ಳುತ್ತದೆ.* *ಓಝೋನ್ ಪರದೆ ಇಲ್ಲವೆಂದರೆ ಭೂಮಿಯಲ್ಲಿರುವ ಜೀವಕೋಶಗಳು ಹೆಚ್ಚು ದಿನಗಳು ಬದುಕಲು ಸಾಧ್ಯವಿಲ್ಲ. ಇತ್ತೀಚಿನ ಆಧುನಿಕ ಜೀವನ ಶೈಲಿಯಿಂದಾಗಿ ಓಝೋನ್ ಪರದೆಯು ತನ್ನ ಗುಣಮಟ್ಟವನ್ನು ಕಳೆದುಕೊಳ್ಳುತ್ತಿದೆ.* 

*ಓಝೋನ್ ಇದ್ದರೆ ನಮ್ಮೆಲ್ಲರ ಉಳಿವು;ಅದಿಲ್ಲವಾದರೆ ನಮ್ಮೆಲ್ಲರ ಅಳಿವು ಶತಸಿದ್ಧ.ಹಾಗಾಗಿ ಓಝೋನ್ ಪದರವನ್ನು ರಕ್ಷಿಸಲು ಮತ್ತು ಭೂಮಿಯ ಮೇಲಿನ ಜೀವಿಗಳ ಜೀವವನ್ನು ಉಳಿಸಲು ಪ್ರತಿಜ್ಞೆ ಮಾಡುವ ಮೂಲಕ ಓಝೋನ್ ಬಗ್ಗೆ ಜಾಗೃತಿ ಮೂಡಿಸುವ ಸಲುವಾಗಿ ವಿಶ್ವದಾದ್ಯಂತ ಪ್ರತಿ ವರ್ಷ ಸೆಪ್ಟೆಂಬರ್ 16ರಂದು "ವಿಶ್ವ ಓಝೋನ್" ದಿನವೆಂದು ಆಚರಿಸಲಾಗುತ್ತದೆ.*

_#ಇತಿಹಾಸ:_

*ಡಿಸೆಂಬರ್ 19, 1994 ರಂದು ವಿಶ್ವಸಂಸ್ಥೆಯ ಸಾಮಾನ್ಯ ಸಭೆ ಸೆಪ್ಟೆಂಬರ್ 16 ರಂದು ಓಝೋನ್ ಪದರದ ಸಂರಕ್ಷಣೆಗಾಗಿ ಅಂತರರಾಷ್ಟ್ರೀಯ ದಿನವನ್ನು ಘೋಷಿಸಿತು. 1987 ರಲ್ಲಿ ಓಝೋನ್ ಪದರವನ್ನು ನಾಶಪಡಿಸುವ ವಸ್ತುಗಳ ಮೇಲಿನ ಮಾಂಟ್ರಿಯಲ್ ಪ್ರೋಟೋಕಾಲ್ಗೆ ಸಹಿ ಹಾಕಲಾಯಿತು.ಸೆಪ್ಟೆಂಬರ್ 16, 1987 ರಂದು, ವಿಶ್ವಸಂಸ್ಥೆ ಮತ್ತು ಇತರ 45 ದೇಶಗಳು ಮಾಂಟ್ರಿಯಲ್ ಶಿಷ್ಟಾಚಾರಕ್ಕೆ ಸಹಿ ಹಾಕಿದವು.

The ozone layer is an important part of our atmosphere, absorbing almost all of the sun’s harmful ultraviolet (UV) radiation.

Long-term exposure to high levels of UV-B, or any exposure to UV-C, is harmful to human health and damaging to most animals, plants and microbes. In short, the ozone layer plays a crucial role in protecting all life on Earth.

In the 1970s, scientists first hypothesised that the ozone molecules (O3) which form the ozone layer could be destroyed by the chlorine from chlorofluorocarbons (CFCs), man-made chemicals which were used in thousands of products around the world, from air-conditioners and refrigerators to aerosol sprays, asthma inhalers and building insulation.

Over the following years, evidence supporting their concerns grew and when scientists discovered a hole in the ozone layer above the Antarctic in the mid-1980s, the international community was spurred into action. The Montreal Protocol was signed in 1987, with the explicit aim of protecting the ozone layer by phasing out ODS.

To this day, the Montreal Protocol is the only United Nations environmental treaty to be ratified by every country in the world and it is defined by a catalogue of successes.

99 per cent of the ODS controlled under the Protocol have been phased out

the ozone layer is recovering and, if the Protocol continues to be fully implemented, should return to 1980 levels by 2066

hundreds of millions of people worldwide will be protected from skin cancers and eye cataracts, resulting in about $1.8 trillion in global health benefits

as ODS are potent greenhouse gases, their phase-out has already avoided hundreds of billions of tonnes of carbon-dioxide equivalent emissions.

in 2016, the Montreal Protocol formally became a climate treaty with the adoption of the Kigali Amendment, a global agreement to phase down production and consumption of hydrofluorocarbons (HFCs). HFCs do not deplete ozone but are climate-harming gases used as substitutes for ODS. Successful implementation of the Kigali Amendment will avoid up to a half a degree of warming by the end of the century.
