Did you have a favorite plastic toy when you were a child? Did it break? Did your parents throw it away? Well, I know where it is. It’s floating(漂浮)in the Pacific Ocean. Well, let me explain how it 89 (get) there.
Many countries put their garbage in the Pacific. Most of the garbage sinks. But plastic floats and 90 (move). The North Pacific Gyre(环流) pulls things towards the middle. So, all the plastic ends up in the same place. One scientist says the area looks just like “plastic soup”.
This “plastic soup” 91 (discover) about ten years ago. Since that time the amount of plastic in his area 92 (increase) a lot. And this plastic will not just go away, it takes 400 years for plastic to degrade(分解). And, even worse, fish and sea birds are eating the plastic. They think it looks like food. The plastic doesn’t kill them directly, but the fish (who are not smart!) think they are full. So, they stop 93 (eat) and die of hunger. Dolphins and whales will also eat plastic and die.
Governments are starting to work together to clean up this area, but it will take many years. That’s why we should always try 94 (recycle) plastic... even our old toys.
