14. deep sea mining presents many technical, political, and environmental prob-
lems. so, polymetallic sulfide deposits produced by the circulation of sea
water through the hot volcanic rocks in some undersea locations has created
significant mineral deposits of zinc, copper, lead, barium, silver, and gold some
known deposits may contain several millions of tons of ore and may be compa
rable with the largest massive sulfide deposits currently being mined on land
what obstacles hinder mining and recovery of these minerals? what aspects of
thining could lead to environmental damage when undersea mining, but not
when mining on land?
