    Imagineyou are taking a walk on the beautiful beach. Just then, your feet step oversomething and you hear a crack (噼啪声) —an empty plastic bottle. Things like thisare happening more often because of sea rubbish.

    Studiesshow that 80%of all the waste is from the land. The waste is mainly plastics (塑料制品) which are really hard todegrade (降解). So the rubbish will remain there for along time. Some of the pollution is caused accidentally. For example, about10,000 product-filled boxes are lost at sea every year from business ships.Sometimes people just throw things into the water from boats or land. Manylarge rubbish areas are formed in the North Pacific Ocean.

   Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and AtmosphericAssociation (NOAA) are taking action to help clean the sea. Since 2006, 76projects have cleared out 3,814 metric tons (公吨) ofrubbish from the sea. Methods of rubbish cleaning include using machines toremove (移除) the waste away from the surface of seawater. Besides, special nets are set by the mouths of rivers to stop therubbish before it reaches the sea. If everyone does his part, sea rubbish seemslike a problem that can be solved.
