EWT Celebrated Int day for the preservation of Ozone layer Skin cancer is 50% increase by depletion of ozone layer Islamabad: Environmental Watch Trust (EWT) celebrated International day for the preservation of Ozone layer. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometers above Earth, though the thickness varies seasonally & geographically. Worldwide ozone day has been celebrated on 16th September and for this year the United Nations Environment Programme (UNEP) give Theme - Ozone Layer Protection: The Mission Goes On. This year’s theme seeks to galvanize all stakeholders to increase their efforts to address the challenges. Chairperson Environmental Watch Trust Shumaila Javed Bhatti said that Ban ki moon Secretary-Generals Message on the International Day for the Preservation of the Ozone Layer eye opener “Recent scientific findings reveal the importance of the Montreal Protocol. Without the Protocol and associated agreements, atmospheric levels of ozone-depleting substances could have increased ten-fold by 2050. Concerted action has prevented millions of cases of skin cancer. Shumaila Javed Bhatti in her opening remarks further said, Bad news is that If we Correlation between Ozone depletion and skin diseases from the scientific record and research it clearly indicate that skin cancer is 50% increase by depletion of ozone layer But Good news is The phase-out of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the earth. PRESIDENT Pakistan Association of Green Agricultural Journalists (PAGAJ) Raja Javed Ali Bhatti said that In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114). States were invited to devote the Day to promote activities in accordance with the objectives of the Protocol and its amendments. The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet. Pakistan Association of Green Agricultural Journalists (PAGAJ) is and will remain media partner in all environment friendly activities to save our mother earth. Dr Tanveer Hussain Chairman Department of Forestry, Range and Wildlife Management Islamia University of Bahawalpur said while we cant stop the effects of global warming completely we can reduce the scale of pollution being released so that future generations can enjoy the planet. If we can decrease the demand for wood being felled in the rainforests we can save vast expanses of oxygen creating trees. It is estimated that each tree can hold 13 pounds of carbon each year. This mounts up to over two and half tones per year that would otherwise be entering the atmosphere. Trees could also be used economically to reduce costs of air conditioning. Where possible trees could be introduced to provide shade over buildings cooling them naturally. Not only would the trees be releasing more oxygen into the atmosphere but there would also be a reduction in Carbon dioxide emissions as less fuel is used on powering air conditioning systems. Muhammad Safeer Department of Forestry, Range and Wildlife Management Islamia University of Bahawalpur said The Montreal Protocol has so far been successful in meeting some of its targets on phasing out ozone-depleting substances. As a result, the abundance of ozone-depleting substances in the atmosphere is declining and the ozone layer is expected to recover around the middle of this century. There are, however, some remaining challenges to the phase-out of ozone-depleting substances.The Department of Forestry Range and Wildlife Management, The Islamia University of Bahawalpur has conducted seminars on protection of Ozone.Dr. Tanveer Hussain, Dr. Muhammad Rafay, Dr. Muhammad Abdullah and students also delivers the lectures on the importance of Ozone, protection of ozone, effects of ozone depletion in our daily life, causes of ozone depletion and how can we protect the Ozone layer. Chief Guest Prof .Dr.Mohammad Yaqoob Soomro Mehran University, SZAB Campus Khairpur Mir said God has created earth and other planets with his own mastery. One of the most important miracles of God is the Ozone layer, it is a protective layer from the intensive ultra-violate (UV) rays for the human being and other life exist on the crust of earth. Engr. Sajjad Ali Mangi Lecturer at Mehran University, SZAB Campus Khairpur Mir In his keynote address said “Actually ozone layer refers to a region of Earths stratosphere that absorbs most of the Suns UV radiation. It contains high concentrations of ozone (O3) relative to other parts of the atmosphere, although it is still very small relative to other gases in the stratosphere. The ozone layer contains < 10 ppm of ozone, while the average ozone concentration in Earths atmosphere as a whole is only about 0.3 ppm. Ozone depletion causes increases in UV rays’s effects on aquatic ecosystems by, decreasing the abundance of phytoplankton – affects the food stock for fishes and the absorption of CO2. Decreasing the diversity of aquatic organisms – reduces food stock and also destroys several fish and amphibians. Damage to plant cell DNA molecules - makes plants more susceptible to pathogens and pests. Reductions in photosynthetic capacity in the plant - results in slower growth and smaller leaves. Causes mutations in mammalian cells and destroys membranes. Harmful effects of UV rays on people. Skin cancer. Premature aging of the skin (different from normal chronological aging). Cataracts and eye disorders (corneal sunburn and blindness). Immune system damage. There are different chemicals are responsible for the destruction of the ozone layer most commons are chlorofluorocarbons (CFC’s), man-made, non-toxic and inert in the troposphere. Chlorofluorocarbons (CFCs) are created and used in refrigerators and air conditioners. These CFCs are not harmful to humans and have been a benefit to us. Once released into the atmosphere, chlorofluorocarbons are bombarded and destroyed by ultraviolet rays. In the process chlorine is released to destroy the ozone molecules. It is observed that each year 75 – 85 % ozone layer damaged by the human activity because CFC production day by day increases. At the end EWT Certificates and shield were also distributed among the participant’s and organizers. *********************************************
