If you believed you needed a big problem in your hands, think about what the people of Sydney, Australia cope with. They are handling pest control underwater generates that traveling on ships and threaten to undermine the organic aquatic life which sustains Australia.
These species comprise the woman crab / Asian encounter crab, acorn barnacle, colonial sea squirt, black striped mussel, and the European zebra mussel, and are one of a set of 56 put together by environmentalists who say that these mollusks are a threat to native Australian colonies. Just how much of a threat? Scientists consider these nuisances could kill off them since they overpopulate and overpower them, especially in high-traffic interfaces.

This is just what occurred with Japanese Steak, which can be so dense, it's overgrown the indigenous seaweed, travel over 5,000 miles in the North Pacific from Japan, according to the Herald in a recent post. The exact same thing has occurred with all the Northern Pacific Seastar, which has destroyed the Tasmanian scallop market.
