Health Effects due to ozone depletion

    Health Effects due to ozone depletion
    • Skin Cancer (melanoma and nonmelanoma)
    • Premature aging of the skin and other skin problems
    • Cataracts and other eye damage
    • Immune system suppression
    • Increased eye burning due to photochemical smog in troposphere
    • Decreased yield of crops
    • Damage to aquatic life and alteration in ocean food webs
    • Increased global warming

    Other Skin Damage

    • Other UV-related skin disorders include actinic keratoses and premature aging of the skin. Actinic keratoses are skin growths that occur on body areas exposed to the sun. The face, hands, forearms, and the "V" of the neck are especially susceptible to this type of lesion. Although premalignant, actinic keratoses are a risk factor for squamous cell carcinoma. Look for raised, reddish, rough-textured growths and seek prompt medical attention if you discover them.

    • Chronic exposure to the sun also causes premature aging, which over time can make the skin become thick, wrinkled, and leathery. Since it occurs gradually, often manifesting itself many years after the majority of a person's sun exposure, premature aging is often regarded as an unavoidable, normal part of growing older. With proper protection from UV radiation, however, most premature aging of the skin can be avoided.

    Cataracts and Other Eye Damage

    • Cataracts are a form of eye damage in which a loss of transparency in the lens of the eye clouds vision. If left untreated, cataracts can lead to blindness. Research has shown that UV radiation increases the likelihood of certain cataracts. Although curable with modern eye surgery, cataracts diminish the eyesight of millions of Americans and cost billions of dollars in medical care each year.

    • Other kinds of eye damage include pterygium (i.e., tissue growth that can block vision), skin cancer around the eyes, and degeneration of the macula (i.e., the part of the retina where visual perception is most acute). All of these problems can be lessened with proper eye protection from UV radiation. World Ozone day is being celebrated every year by 16th of September.
