Save our oceans

The ugly journey of our trash

The fish came back with just minor deformations. Scientist and the government told us that eating fish had no influence on our health
Water level is still rising and even the predators came back

Ten common causes of water pollution

Sewage and wastewater: Out of sight, out of mind? Divers will tell you that sewage contains all kinds of horrific nasties, from sanitary products, condoms, paper, and plastics, to bacteria and viruses that can make you extremely ill.

Soaps and washing detergents: Phosphates in detergents can fertilize rivers and seas, causing algal blooms that use up oxygen and kill fish life.

Oil poured down the drain: You might think oil tankers make the most oil pollution, but quite a lot of oil enters water simply by being tipped (or washing) down the drain.

Invasive species: Often carried around the world by ships, they suddenly appear in rivers, lakes, and seas where they have no predators, quickly wiping out their natural rivals.

Atmospheric deposition: This is air pollution that returns to Earth as land and water pollution, including acid rain that falls into oceans, rivers, and seas, chemical discharges from chimneys (smokestacks), and fly ash from waste incinerators.

Highway and street runoff: Cars obviously wear out as they drive down roads—but it's less obvious that they wear out and leave toxic residues on the roads themselves. Heavy storms wash poisoned sludge off roads into surrounding land where it drains into rivers or groundwater.

Agricultural runoff: Fertilizers, weedkillers, and other farm chemicals wash into rivers and groundwater, causing algal blooms and potentially contaminating drinking water.

Litter: Plastic bottles and bags can last up to 500 years in the environment without biodegrading (breaking down naturally). If you've ever done a beach clean and studied the waste you collect, you will have noticed that the vast majority of it is small, random bits of plastic.

Oil production: Most oil is produced offshore and transported by ships, so it's no surprise that the oil industry is a big polluter. Despite the huge media attention they gain, tanker accidents account for only about 10 percent of the total amount of oil that enters the oceans. Unfortunately, they often create a huge amount of pollution in one place, overwhelming the local ecosystem.

Ship pollution: Several decades after important international agreements to stop marine pollution were signed, oil leakage and waste disposal from ships (including cruise ships, warships, and tankers) remains a significant cause of ocean pollution.
