The zebra mussel is causing a very large threat
to North America's industrial, agricultural and
municipal water supplies, and it could become a
costly nuisance for freshwater shipping, boating,
fishing, and claming as well. First found in the
Great Lakes in 1988, the zebra mussel could
become more widespread than the German carp and
cause way more economic damage than the
Mediterranean fruit fly.
