  • 1. Will ClarkENC 1102-CRN 10844 April 4, 2013
  • 2. Ozone is a gas that develops naturally in our atmosphere.Most of it is concentrated in the ozone layer, a regionlocated in the stratosphere several miles above thesurface of the Earth. Although ozone represents only asmall part of the gas in the atmosphere, it is an extremelyimportant factor in protecting humans and other life onEarth from Ultraviolet light from the sun.
  • 3. Although there are many people who believethat the depletion of the ozone layer is notdirectly impacting their lives, the problemneeds to be considered as ozone depletion iscreating dangerous consequences.
  • 4. Big BusinessIn order for major corporations to create a mass amount of product to sell they mustuse industrial foundries and transportation that emit harmful gasses into the air thatcontinue to deplete our Ozone. “Certain industrial processes and consumer productsresult in the atmospheric emission of ozone-depleting gases. These gases containchlorine and bromine atoms, which are known to be harmful to the ozone layer.Important examples are the CFCs and hydrochlorofluorocarbons (HCFCs), human-produced gases once used in almost all refrigeration and air conditioning systems.These gases eventually reach the stratosphere, where they are broken apart to releaseozone-depleting chlorine atoms. Other examples are the halons,which are used in fireextinguishers and which contain ozone-depleting bromine atoms”.
  • 5. What the heck is the Ozone??Many people are not even aware of what isgoing on in our atmosphere. Not only that, butthey do not know what the Ozone even is, whatis destroying it, and how much it could affecttheir life.
  • 6. Why should we try and stop Ozone Depletion?• Health issues are arising from this.• Plant life, animal life, and overall production of food are being affected.• To keep our atmosphere from collapsing.
  • 7. Health issuesMany issues have come up from the depletion of the Ozone. With no Ozone to protect us from UltraViolet rays this leaves us exposed and vulnerable to the harmful rays. These harmful rays leave manyterrible effects on humans. Effects include skin cancer, eye cancer, damage to the immune system andothers.• Scientific Research Examples:• Effects on skin• • Malignant melanoma • Non-melanocytic skin cancer—basal cell carcinoma, squamous cell carcinoma • Sunburn • Chronic sun damage • Photodermatoses.• Effects on the eye• • Acute photokeratitis and photoconjunctivitis • Climatic droplet keratopathy • Pterygium • Cancer of the cornea and conjunctiva• • Lens opacity (cataract)—cortical, posterior subcapsular • Uveal melanoma • Acute solar retinopathy • Macular degeneration.• Effect on immunity and infection• • Suppression of cell mediated immunity • Increased susceptibility to infection • Impairment of prophylactic immunization • Activation of latent virus infection.
  • 8. Effects on the EcosystemThere is an ecological dimension to consider.Ultraviolet radiation impairs the molecularchemistry of photosynthesis both on land(terrestrial plants) and at sea (phytoplankton). Thiscould affect world food production, at leastmarginally, and thus contribute to nutritional andhealth problems in food- insecure populations (). Ifplants cannot produce properly animals will nolonger have food to eat. If animals do not eat theywill die hence humans will no longer have a sourceof food. The rays are destroying the earth and itsbountiful green food.
