Imagine you are taking a walk on thebeautiful beach. Just then, your feet step over something and you hear a crack(噼啪声) —an emptyplastic bottle. Things like this are happening more often because of searubbish.
Studies show that 80% of all the waste isfrom the land. The waste is mainly plastics (塑料制品)which are really hard to degrade (降解). So the rubbishwill remain there for a long time. Some of the pollution is causedaccidentally. For example, about 10,000 product-filled boxes are lost at seaevery year from business ships. Sometimes people just throw things into thewater from boats or land. Many large rubbish areas are formed in the NorthPacific Ocean.
Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and Atmospheric Administration (NOAA)are taking action to help clean the sea. Since 2006,76 projects have clearedout 3,814 metric tons (公吨) of rubbish from the sea.Methods of rubbish cleaning include using machines to remove (移除) the waste away from the surface of sea water. Besides, specialnets are set by the mouths of rivers to stop the rubbish before it reaches thesea. If everyone does his part, sea rubbish seems like a problem that can besolved.
