About 71% of the Earth's surface is covered in oceans.
Around the world sewerage, chemical waste and oil are discharged into the sea.
Millions of pieces of litter are dumped into the sea each day. An estimate a couple of year's ago stated that there were 46,000 pieces of discarded plastic floating on every square mile of ocean; responsible for killing a million seabirds each year.
Disposing of waste this way may have once seemed to be a drop in the ocean but the rubbish is now all too visible to ignore.
