The effects of increased ultraviolet radiation 1991

  The effects of increased ultraviolet radiation on underwater life are said to be unimaginable. Dr. Denib Karentz of the University of California, USA, placed UV-sensitive E. coli bacteria in the ocean around Antarctica for observation and reported that as the ozone hole became larger and the amount of UV light transmitted increased, the E. coli bacteria died one after another. And this, he says, suggests that plankton and other organisms in the ocean are more sensitive to ultraviolet radiation.

  Experimental data has shown that a 20% increase in ultraviolet radiation causes a 20% decrease in grain yield. It is also projected that $2 billion in damage to materials such as plastics and paints will occur each year.
