And when flushed into strange waters, these organisms can take over, with devastating effect. An infestation of zebra mussels began to radically change the Great Lakes ecosystem in the 1980s, and the MSX virus depleted the oyster population of Chesapeake Bay in the 1950s. Scientists have traced both disruptions to ballast water...

The British claim, and those that are sure to follow, amounts to a long-shot move that enables resorting to a future temptation. For the sake...
