Facts about Ocean Pollution

Ocean pollution is a very severe problem and it’s not something to be taken lightly. This type of pollution is responsible for so much damage around the world, and it is only getting worse. There are a lot of people out there working to reverse and prevent further damage, but there’s still a long way to go, too. Here are some facts to keep in mind when you’re learning about ocean pollution and trying to figure out what you can do to make a difference in the fight against this major worldwide problem, too.

thermal pollution solutions
  • Ocean pollution happens when harmful substances enter ocean water. These substances can include waste, bacteria, viruses, other damaging organisms, chemicals, particles and more. This may also refer to thermal pollution, which raises the temperature of the water in a given location to unsafe levels for that area.
  • Plastic is the most common pollutant in the ocean. Plastic garbage that washes into the ocean begins leeching harmful chemicals into the water almost right away. Unfortunately, even though we know this, we continue to dump plastic into the water anyway, and this causes further harm. There is a lot of plastic present in the ocean as it is, and more and more is being dumped there every day.
  • Waste dumped into the ocean eventually washes up onto beaches. A company may think they’re getting away with something by dumping their wastewater out into the middle of the ocean, but that water has to go somewhere. It’s not just going to stay out there in the middle of nowhere forever. Eventually, it will find its way to beaches where humans are trying to relax, and it may impact economies and residential communities as it builds up there.
  • There is a large deposit of trash in the ocean that is twice as big as Texas. There are many trash deposits floating in the ocean like this, but this one is the largest. It is known as the Great Pacific Garbage Patch or the Pacific Trash Vortex. This “trash island” is trapped in the area due to the currents of the North Pacific Gyre, and so it stays there, drifting in the same location and severely polluting the water with chemicals, plastic, debris, and sludge indefinitely. It is also responsible for spreading invasive species in the area.
  • The ocean is also polluted by toxic metals. Metal substances present in the water come from runoff related to factories, power plants, and agriculture. As this water slowly reaches the ocean, it causes pollutants to build up there, including mercury, arsenic, and other very dangerous substances. There are some part of the ocean where this is significantly worse than others.
  • Oil spills are responsible for 12% of the ocean’s pollution. This may sound like a lot initially, but in fact, oil spills are one of the less problematic pollutants in the ocean today. We hear about them more often than other pollution issues because they appeal to human emotions, but oil spills happen because of accidents, so they aren’t really all that common in comparison to purposeful pollution that is caused by runoff, dumping, and wastewater issues.
  • Radiation is another common ocean pollutant. Nuclear power plants frequently deposit their nuclear waste in and around water sources, and this eventually reaches the ocean. Radioactive pollution in the ocean increases significantly when accidental tragedies happen to cause nuclear meltdowns at power plants as well. This is very uncommon, but there is still radioactive pollution present in the ocean from as far back as the Chernobyl incident.
  • The ocean already contains dead zones because of pollution. Algal blooms occur when pollution related to heavy metals and nutrients gets out of hand, and these are already rampant in the ocean. Over time, these blooms are no longer able to be stopped, and they kill off massive spaces of water in the ocean. These dead zones are getting more and more common, and they are affecting animal life as well as human life as they spread.


How big of a problem is ocean pollution, really? How soon do we need to take action against it? In short, we need to get started right now. We may already be too late to reverse all the damage that’s been done to our oceans, but it’s never too late to start working on preventing further damage in the future. Water pollution is one of the biggest problems facing the earth today, and so far, we haven’t done a lot to change that. However, groups have been working to improve the situation worldwide, and although it’s a slow process, we are making a difference.

ocean pollution facts

If you’re looking to get involved fighting back against this problem, you should absolutely get started as soon as you possibly can. You may feel that there’s not much you can do, being just one person, but this is not true at all. Every person can make a difference, and if you start making positive changes in the way you live, your friends and family are likely to follow too. The more we all work together, the better off our oceans will become, even if it takes time to get there. This is not a losing battle, but we have to get started fighting it right away.
