Nurdles make up 10 percent of the ocean's plastic trash. What is a nurdle?
a small piece of plastic
A nurdle is a small piece of plastic formed by photodegradation. Plastic doesn't chemically change as it decays -- it breaks down into smaller and smaller pieces over time. Also, a nurdle can refer to the basic form of plastic used to make other products.
a Styrofoam pellet
a noodle-shaped marine animal

Nurdles are a threat to marine life because:
Animals that swallow them become more buoyant and can't stay underwater.
The nurdles contain concentrated toxins that can poison the animals.
Nurdles act like sponges in the ocean and absorb toxins. The toxins are concentrated in the nurdle and can be detrimental to marine life.
Animals that eat nurdles think they are full and eventually starve.
