all our seas and oceans are polluted, but the barents and kara seas,south of the arctic ocean, are more polluted than all the others. it is amazing how much waste has been dumped
there. it is known that 14 nuclear reactors,one nuclear submarine with fuel and thousands of barrels of chemicals have been sunk there. it's not certain what yhis has done t the environment,but norwegian scientists believe that in some places there is enough radioactive material in the arctic food chain to destroy whole families of sea life.
