Around half of all ocean pollution is caused by sewage and waste water. Each year, the world generates perhaps 5–10 billion tons of industrial waste, much of which is pumped untreated into rivers, oceans, and other waterways.
So many people dumb there trash on in the rivers or oceans and sea animals get hurt or maybe they die! That is why people are so lazy of putting things in the trash can.
Hope I helped. If I did help, make me that Brainliest.
