outside their normal behavior. 22 As a result of extensive war measures, large quantities of radioactive materials
have been dumped into this area. The consequences produced by these materials, when in touch with a living organism,
are unpredictable. For example, the clownfish in the Borneo area are losing their immunity to the defensive extracts of
certain plants in the area, thus breaking the symbiotic relationship these animals and plants have shared for
centuries. 23
Last year the first serious omen of disaster was spotted near the Atlantic coast of Northern America. 24 The
humpback whale in question had fins as large as the rest of its body. This species lives solely on plankton and has
started to grow teeth as a result of changes in the gene pool induced by radioactive plankton. The teeth are uncannily
similar to the teeth of a great white shark, except for being five times larger. 25 Whereas these whales once were 12
meters long, they now reach a length of 15 meters.
