The most visible and disturbing impacts of marine plastics are the
ingestion, suffocation and entanglement of hundreds of marine species
. Marine wildlife such as seabirds, whales, fishes and turtles, mistake plastic waste for prey, and most die of starvation as their stomachs are filled with plastic debris.
What are the causes and effects of marine pollution?
The non-point sources like
wind-blown debris, agricultural runoff, and dust
become the major source of pollution. Apart from these, factors like land runoff, direct discharge, atmospheric pollution, pollution caused by ships, and deep sea mining of natural resources contribute heavily.
What are the effects of marine pollution?
Pollutants in the ocean make their way back to humans. Small organisms ingest toxins and are eaten by larger predators, many of which are seafood that we eventually eat. When the toxins in contaminated animals get deposited in human tissue, it can lead to
long-term health conditions, cancer and birth defects
.

What are the long term effects of marine pollution?
Long-term effects can include
reproductive system failure, behavioral changes, cancer, and death
. When oil is spilled into the ocean, it sits on the water surface and keeps the sunlight from getting to marine plants affecting the photosynthesis process.
What is the biggest cause of marine pollution?
Most ocean pollution begins on land.
Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called
nonpoint source pollution
, which occurs as a result of runoff.
