The Most Unpolluted Waters are..
the waters in the deep northern
Pacific.
q The man-released CFC and the chemical
tritium and C14, which were
released through atmospheric atomic bomb test in the 1950s and 1960s, entered
the
deep ocean in the northern Atlantic and are still
moving southward slowly.
q Those pollutions just cross the equator in
the Atlantic è They
have not reached the deep northern Pacific yet!!
