[Challenge:Future] O3 Redemption

  1. 1. Surya JaisankarRakshith KunchumG.AnirudhIIT ROORKEEINDIA
  2. 2. Decimation of Ozone layer over a regionOZONE LAYER is the protective bubble around the earththat shields the harmful Ultra Violet raysWith every coolant system technologically built sofar, we are depleting ozone layer bit by bit by releasingCFCs. BIGGER PICTUREWhen a single atom can trigger and carry out depletionupto 2 years,Overriding the tiny paced depletion, we present thesudden and chronic erosion of the O3 layer!Cl + O3 → ClO + O2ClO + O3 → Cl + 2 O2 →.............
  3. 3. Ozone can be destroyed by a number of free radical catalysts.(OH·) (NO·) (Cl·) (Br·)(F.).UV Rays liberate them from their active compounds. Possibilities??• An alien spacecraft releases these harmful compounds(radicals) in exorbitant amounts.SUPERSONIC AIRCRAFTS ARE KNOWN TO BE RELEASING NO.• Extra-terrestrial events along the lines of solar flares and solar wind ,resulting in the release of these decimating radicals.OH RADICALS HAVE BEEN FOUND IN IN MANY STARS• OR Simply release of a catalyzing substance from space that proliferates the existing depletion due to man-made sources!!! LETS SEE THE CONSEQUENCES
  4. 4. IF THE UV RADIATIONS FIND THEIR WAY TO THE EARTH, they will result in:- Disruption right at the foundation of the food chain, which leads to a cumulative effect on the ecosystem.UV radiations kill Phytoplankton. Less phytoplankton means less foodfor the sea animals to eat. It is estimated just a 16 % ozone depletionindirectly leads to a loss of about 7 million tons of fish per year. Thehuman food supply already strained due to demands of an everincreasing population, reductions resulting from UV damage may be disastrous to many people, especially the poor and indigenous. IMAGINE THE EFFECT OF DECIMATION OF OZONE AND THE CONSEQUENCES Extremely high UVA radiations exposure leading to skin cancer.Whatever sunscreen solutions we have right now can only overcomethe problem of UVB radiations but not UVA.The health risks areBasal and squamous cell carcinomas, malignant melanoma, cataract, etc, etc.
  5. 5. Experts predict that an estimated 10 % reduction in the ozone layerwill result in a 25 % increase in non-melanoma skin cancer ratesIt also damages the DNA of marine bacteria and the larvae ofstarfish and urchins. And it even alters oceanchemistry, creating potentially dangerous substances in thewater itself and cause biological damage by oxidizingbiological molecules.
