The Potential Effects Of A Depleted Ozone Layer
"And God said, let there be light and there was light and then God saw the
light, that it was good " ( Genesis 1: 3-4 ). Undoubtedly, light is good.
Without light man could not survive. Light is the ultimate cosmic force in this
universe allowing man to progress and flourish. In the form of heat, light from
the sun warms the Earth. Light, also, is the single most important factor
influencing the growth and development of plants. Photosynthesis, a process by

accelerates the pace at which man must decide what to do with the dilemma of a
booming and more importantly hungry population. Conceedingly, plants, as any
element of life, have been known to adapt to contemporary and dangerous changes
in its surroundings but it cannot be dismissed that " UV radiation can also
