A big part of the Pacific Ocean is choking on a huge sea of plastic garbage. Some scientists think it’s as large as the UnitedStates, but almost no one noticed it until 1997. Then, an adventurer named Charles Moore made a shocking discovery, and scientists
learned the ugly truth.
Moore was the captain of a sailboat that had just completed a race. He planned to sail home from Hawaii to California. Theusual route went south, then east. The winds are strong there, and boats move quickly. Moore, however, was not in a hurry. He
decided to sail directly east—a slow route with weak winds. This region gets few visitors, so Moore was sailing into almost unknownwaters.
What Moore found in the lonely North Pacific was a shock. Floating under the ocean’s surface was a “soup” of plastic garbage.
It was thick with billions of tiny plastic pieces the size of apple seeds. They made a clicking sound against the sides of the boat as
it sailed along. Everyday plastic objects, such as shopping bags and water bottles, were trapped among the tiny pieces. In the(1)middle of the ocean, a thousand miles from the nearest town, the sea of garbage [ Moore as stretched could as see far ] .
Moore and Curtis Ebbesmeyer, a researcher, began calling this area the Great Garbage Patch. Ebbesmeyer was an expert inocean garbage.

In the 1990s, he studied shipping accidents that spilled big loads of sports shoes and plastic bath toys into the ocean.
AOcean currents pushed the shoes and toys along. The movement of the objects revealed where currents flow in some parts of thePacific.
Oceanographers are not surprised that garbage collects in the North Pacific. A pattern of winds and currents, called the North
Pacific Gyre, gathers this garbage.

Water in the gyre goes round and round in a clockwise pattern, and anything that gets into theBmiddle of it is trapped. This natural process has continued for millions of years. Organic garbage, such as food, tree branches, andpaper, gets broken down by bacteria and chemicals. It returns toits original parts and re-enters the environment. The difference(2)is that now most of the garbage is plastic, and plastic is inorganic. Bacteria and chemicals in the seawater cannot break
it down.
(3)
Plastic will therefore stay in the environment for hundreds or even thousands of years.
Some oceanographers doubted Moore’s reports. Why didn’t satellite pictures show the patch? Where did all this plastic comefrom? Is it really a problem? If so, how do we solve it? Moore learned some answers during return trips to the Great Garbage Patch.
Satellites don’t see the plastic because most of it hides under the ocean’s surface. Some of the plastic comes from ships, but most of
it is washed into the ocean from cities beside the Pacific.
The Great Garbage Patch is a real problem because the plastic in it is harmful to animals. To fish and birds, a piece of plastic canlook like food. The animal eats it, and the plastic gets stuck inside. This makes it harder for an animal to eat real food. Toxins fromocean water also get into the body of an animal because toxins stick to the plastic. These poisonous chemicals can kill the animal ormake (4) it sick.
