What do scientists call plastics when they break down into tiny pieces?
Microtrash
Microplastics
Microparticles

According to the article, humans are also ingesting plastic that has ended up in the ocean. How is this possible.
The tiny plastic particles in the ocean end up coming through the faucets in our sinks once the salt water is converted to fresh water.
The fish in the ocean eat the plastics and humans eat the fish, causing the toxic chemicals from the plastics to spread from the fish to humans.
Humans are mistaking plastics in the ocean for food just as the marine life and sea birds are.
All of the above.
Which continent does most of the plastic go to?
North America
South America
Europe
Asia

A catchment is...

They make the natural landscape green and lush.
Rivers and lakes help keep us cool in Summer.
It is where our drinking water comes from and where all food is grown.
This is the part where solid wastes are allowed to settle down and light floatable wastes rise
