3. OZON LAYER DEPLATION
• OZON LAYER DEPLATION ,IS
SIMPLY THE REDUCTION OF THE
AMOUNT OF OZON IN THE
STRATOPHERE. UNLIKE
POLLUTION, WHICH HAS MANY
TYPES AND CAUSES, OZONE
DEPLETION HAS BEEN PINNED
DOWN TO ONE MAJOR HUMN
ACTIVITY.

4. WHY SHOULD WE PROTECT OZON LAYER?
OZON LAYER ACT AS A FILTER THE SHORTER
WAWELENGTH AND HIGHLY HAZARDOUS ULTRAVIOLET
RADIATION (UVR) FROM THE SUN, PROTECTING LIFE ON
EARTH FROM ITS POTENTIALLY HARMFUL EFFECTS.

5. CAUSE OF OZON LAYER DEPLATION
➢THE MAIN CAUSE OF OZON
LAYER DEPLECTION IS
DETERMINED AS EXCESSIVE
RELEASE OF CHLORINE
AND BROMINE FROM MAN-
MADE COMPOUNDS SUCH
AS CHLOROFLURO
CARBONS (CFCs).
➢EMISIONS OF CFCs HAVE
ACCOUNTED FOR ROUGHLY
80% OF STARTOPHERIC
OZON DEPLECTION.

6. HOW TO PROTECT OZON LAYER DEPLETION
1. DESIST FROM USING PESTICIDES.
2. DISCOURAGE DRIVING OF PRIVATE VEHICLES.
3. UTILIZE ENVIRONMENTLLY FRIENDLY CLEANING PRODUCTS.
4. PROHIBIT THE USE OF HARMFUL NITROUS OXIDE.

7. BUY AIR-CONDITIONING AND REFRIGERATION
EQUIPMENT THAT DO NOT USE HCFC AS
REFRIGERANT.
