Decimation of Ozone layer over a region

OZONE LAYER is the protective bubble around the earth that shields the harmful Ultra Violet raysWith every coolant system technologically built so far, we are depleting ozone layer bit by bit by releasing CFCs.

When a single atom can trigger and carry out depletion upto 2 years,Overriding the tiny paced depletion, we present the sudden and chronic erosion of the O3 layer!

Cl + O3 → ClO + O2

ClO + O3 → Cl + 2 O2 →.....

........

BIGGER PICTURE

UV Rays liberate them from their active compounds.

Possibilities??

• An alien spacecraft releases these harmful

compounds(radicals) in exorbitant amounts.

• Extra-terrestrial events along the lines of solar

flares and solar wind ,resulting in the release

of these decimating radicals.

• OR Simply release of a catalyzing substance from space that proliferatesthe existing depletion due to man-made sources!!!

Ozone can be destroyed by a number of free radical catalysts.(OH·) (NO·) (Cl·) (Br·)(F.).

SUPERSONIC AIRCRAFTS ARE KNOWN TO BE RELEASING NO.

OH RADICALS HAVE BEEN FOUND IN IN MANY STARS

LETS SEE THE CONSEQUENCES

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 bedisastrous to many people, especially the poor and indigenous.

IMAGINE THE EFFECT OF DECIMATION OF OZONE AND THE CONSEQUENCES

Whatever sunscreen solutions we have right now can only overcomethe problem of UVB radiations but not UVA.

The health risks are Basal and squamous cell carcinomas, malignant melanoma, cataract, etc, etc.

Disruption right at the foundation of the food chain, which leads to a cumulative effect on the ecosystem.

IF THE UV RADIATIONS FIND THEIR WAY TO THE EARTH, they will result in:-

Extremely high UVA radiations exposure leading to skin cancer.

Experts predict that an estimated 10 % reduction in the ozone layer will result in a 25 % increase in non-melanoma skin cancer rates

It also damages the DNA of marine bacteria and the larvae of starfish and urchins. And it even alters ocean chemistry, creating potentially dangerous substances in the water itself and cause biological damage by oxidizing biological molecules.
