Africa-Press – Mauritius. <\/strong><\/span>The hole above the Earth\u2019s ozone layer on the Antarctic \u201cwill have adverse impacts on the planet and human life,\u201d an expert told Anadolu as the hole is among the largest recorded, about three times the size of Brazil.<\/p>\n

The ozone layer acts as a natural shield, efficiently filtering harmful solar radiation, particularly ultraviolet (UV) rays. The hole\u2019s size variability is influenced by a strong wind band around Antarctica, a result of Earth\u2019s rotation and temperature differences.<\/p>\n

The band acts as a barrier, isolating air masses over polar latitudes. Professor Parisa Ariya, an expert in chemistry and atmospheric and oceanic sciences at McGill University, told Anadolu how the substances catalytically destroy ozone, posing risks to human health and the environment.<\/p>\n

Ariya said human-made emitted gaseous and halogenated molecules have caused a significant decrease in the ozone layer, \u201cand thereby, the ozone layer\u2019s capability to filter the harsh radiation and expose us to stronger radiation with adverse health effects.
\nIn 1987, two years after the discovery of the ozone layer, heads of state and government gathered to sign the Montreal Protocol on Substances that Deplete the Ozone Layer, banning the use of chlorofluorocarbons (CFCs) \u2014 chemicals that deplete the protective layer.<\/p>\n

Despite the signing of the Montreal Protocol, Ariya insists that vigilance and updated protocols are imperative. \u201cWe need to be more aware of these developments and have safeguards by evolving even further the original Montreal Protocol,\u201d she said.<\/p>\n

Ozone, also identified as a \u201cgreenhouse gas,\u201d plays a crucial role in regulating climate by trapping heat, said Ariya. Scientific advancements, including satellite technology and spectrometers, enable accurate monitoring of ozone levels.<\/p>\n

Ariya reported steady recovery trends but urged continuous vigilance and observation to ensure sustained progress. She emphasized that some of the halogenated compounds that are not yet banned and are used, for instance, in Asia, notably China, for agriculture and other purposes, are emitting and will have adverse effects on the planet and humans.<\/p>\n

She stressed that several sustainable alternatives exist, however, vigilance is crucial to prevent the release of hazardous materials. Ariya urged a drastic reduction in emissions affecting climate change, air quality and health.<\/p>\n

To protect the ozone layer, Ariya urged targeted efforts in cities where a significant portion of pollutants is emitted. Advocacy for cleaner cities, sustainable transport and lifestyle changes are essential in reducing human effects.<\/p>\n

Ariya stressed the importance of long-term protection by bringing stakeholders together. \u201cWe must remain vigilant and observe for a long time to ensure it will steadily recover in the long term,\u201d she said.<\/p>\n

\u201cWe also have to adjust the regulation appropriately with the change of emitters and other processes that are linked to ozone transformation in the future.\u201d<\/p>\n
