LIFE & CAREER SKILLS

The hull, or outside, of a ship is said to be fouled

when plants and animals attach to it. For years,

few people connected hull fouling to invasive

species. Most scientists assumed that aquatic

invaders traveled only in ballast water.

Then some scientists began to look more

closely at fouled hulls. They found that millions of

organisms could be riding on the hull of a single

ship. These new observations made many people

change their minds. Now some experts believe

that fouled hulls carry more invaders than ballast

water does. How do you think this new theory will

affect human efforts to control aquatic invaders?
