EARTH BECOME A HEALTHY PLANET ON 2030
September 16: On December 19, 1994, the UN General Assembly proclaimed September 16 to be the International Day for the Preservation of the Ozone Layer, commemorating the date when the Montreal Protocol on Substances that Deplete the Ozone Layer was signed in 1987. The day was first celebrated on September 16, 1995. The theme for this year is “OZONE LAYER 32 YEARS OF HEALING”The International Day for the Preservation of the Ozone Layer is observed on 16 September every year since 1995. This date has been chosen by the United Nations General Assembly in its resolution to remember the signing of the Montreal Protocol in 1987. The ozone layer is a natural part of our atmosphere.It acts like a protective sun screen by blocking harmful ultraviolet rays from the sun.Certain chemicals—such as CFCs, HCFC, and halons—can damage the ozone layer.These can cause holes to form in thelayer and allow more UV rays to reach the earth’s surface.As a result of ozone depletion there will be increase in earth’s temperature, melting of glaciers, cancerous diseases, rise in the level of ocean and many more.Our Queen Azhi Jetsun Pema-the ozone diplomat of Bhutan is still working very hard to have a well protected ozone layer. Therefore in fulfilling her Majesty’s dream of keeping ozone layer safe, there are many and simple ways in which we cansave our ozone layer chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. These chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants. CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer. ENVIRONMENTAL EFFECTS OF OZONE DEPLETION Effects on Aquatic Ecosystems Effects on Biogeochemical Cycles Effects on Air Quality Ozone and UV ChangesOzone and UV Changes Materials Damage Effects on Terrestrial EcosystemsEffects on Terrestrial Ecosystems amage to DNA and leads to mutation damage to skin cells ageing of skin cause various types of cancers snow blindness cataract simple ways in which we can save our ozone layer. Avoid buying and using aerosols and sprays made up of CFC. Avoid using fire extinguishers which destroy the ozone layer. .Choose to buy a refrigerator or AC without CFC. Use alternative means of transport: buses, bicycles, or simply walk or carpool. Follow 4R’s policy-reduce, reuse, refuse and recycle things at home and school Buy energy saving gadgets and bulbs All of us can contribute to the protection of the environment. Solutions to Ozone Layer Depletion Depletion to ozone layer depletion does not affect a region or a country. In fact whole world is vulnerable to its after affects. The increase in the levels of UV rays lead to high rate of skin cancer and eye related problems. Lets have a look at some of the solutions to ozone layer depletion. Avoid products that results in ozone depletion If you are out for shopping, don’t buy aerosol products with chlorofluorocarbons. Do check your fire extinguishers if “halon” or “halogenated hydrocarbon” is the main ingredient. Dispose of old air conditioning units, refrigerators that use chlorofluorocarbons to function. This could release the toxic chemicals into the atmosphere. Advocate for ozone protection Fertilizers and pesticides are extensively used in agriculture and are also a source of nitrous oxide production which is the main culprit in depletion of ozone layer. Encourage local political representatives to raise a campaign to put forth laws governing fertilizer use. Ozone layer depletion is something that could prove hazardous for the entire human community. Speak to your friends, family members, colleagues and encourage them to drive less, eat local, to dispose of fire extinguishers and air conditioning units containing ODS (ozone depleting substances).
