INTERNATIONAL DAY FOR THE PRESERVATION OF OZONE LAYER - SEPTEMBER 16
OZONE LAYER WAS DISCOVERED BY TWO PHYSICTS - HENZRI BUISSON AND CHARLES FABRY IN 1913 . OZONE IS A FORM OF OXYGEN AND IS ONE OF THE MANY LAYERS WITHIN THE EARTH'S ATMOSPHERE THAT HAS THE ABILITY TO ABSORB ALMOST 99 % OF THE SUN'S ULTRA VIOLET RADIATION OTHERWISE THIS ULTRA VIOLET LIGHT COULD POTENTIALLY DESTROY LIVING THINGS AND CREATURES ON EARTH. SCIENTISTS REVEALED THAT THIS LAYER IS GRADUALLY DEPLETING DUE TO HUMAN ACTIVITIES SUCH AS CARBON EMISSIONS FROM INDUSTRIALISED COUNTRIES. (CFC) CHLOROFLUROCARBON WAS DEVELOPED IN 1930 AS AN ALTERNATIVE TO AMMONIA FOR THE PURPOSE OF REFRIGERATION. CHLOROFLUROCARBON CONTAINS CARBON, CHLORINE AND FLUORINE WHICH IS ONE OF THE MAIN OZONE LAYER DEPLETING SUBSTANCE. WHEN CHLOROFLUROCARBON (CFC) GETS INTO STRATOSPHERE THE ULTRA VIOLET RADIATION FROM THE SUN BREAKS UP THE CFC's . THIS ACTION RELEASES CHLORINE ATOMS WHICH REACT WITH OZONE LAYER AND DESTROY THE GOOD OZONE MOLECULES IN THE STRATOSPHERE. ONE CHLO...
