13 Effects of Sewage in The Sea

Sponsors Link

The pollution that occurs in the sea today is mostly caused by humans who often dispose of the remaining waste in the waterways. Where the waste is carried away and eventually ends in the sea. There is a lot of pollution that occurs, for example, oil spills, mixing sea water with industrial waste, fishing with explosives, and garbage carried by rivers and so on. Hence the effects of plastic on Sea Turtles.


Waste produced from hazardous materials can certainly damage the environment, including the environment in the sea. There are many effects of pollution that endanger marine life, for that please know the effects of sewage in the Sea that can affect the beauty of the sea as below:

1. Affects sea water

One of the effects of waste that pollutes seawater can turn seawater into cloudy, smelly, water temperatures to change and many more. If seawater changes due to waste, animals and another biota that live on the surface of the water will be threatened. Can be a cause of poisoning, disease, and habitat extinction. This clearly affected their survival at sea. Why is the Seawater salty? here is the explanation.

2. The color of the sea water changes

Impacts from other wastes can also cause changes in the color of water in the sea. Examples can make water more turbid and not feasible when seen, such as waste due to oil spills that can make seawater black, smelly, oily and dangerous for animals around it. Not to mention another waste that can change temperature, odor, and health like PH water becomes unhealthy. Therefore, if contaminated waste is not immediately handled, it will affect the habitat and the marine environment increasingly polluted.

3. Salinity or salt contained in Seawater

The next effects of sewage in the sea are the salinity and impact of salt in the sea. The waste that pollutes the ocean can increase the salt content of the seawater. If this happens, the impact can certainly threatened animals and other creatures that live on the seawater surface or below them. Habit and population will decline, as well as underwater environments such as plants, coral reefs, and fish seeds will be contaminated with waste. Hence the things you must know about Dead Sea.

4. Contamination of biota in the sea

The impact of waste that is disposed of or pollutes the ocean can, of course, destroy the biota in the sea whose life is indeed in the water. Waste contaminated with toxic or dangerous substances can disturb habitat, reproduction, seeds, and breeding of creatures. This if it often happens will eventually cause damage, and the population of marine animals will decline or over time will become extinct due to contamination of waste.

5. Damaging the population of marine biota

In addition, the waste factors that occur in the oceans have an effect on population damage to their habitat. The animal population in the sea depends on the condition of the seawater itself, if a lot of waste pollutes, of course, it will have an impact on damage, such as garbage waste will damage animal habitat, oil waste to destroy animals and other waste can also affect more serious factors. Animal extinction will continue to occur if pollution is not addressed properly and correctly. The reason why the Sea looks bluish and greenish.

6. Damage reproduction on biota in the sea

The effects of sewage in the Sea is that it can inhibit the reproduction process in animals and other creatures in the sea. Waste makes it difficult for animals to reproduce properly so that seeds such as eggs or breeding processes in fish and so on are disturbed. It can even cause it to fail, resulting in a decline in population. If this continues it can cause infertility in animals and come to extinction.

7. Making extinctions on marine animals

Many cases of waste pollution that occur in the oceans of this world. Not only from various industries but also from household waste such as plastic carried to the sea. The serious impact that can affect marine biota is that the population decreases and reaches the level of extinction. It can be imagined if the marine ecosystem is disturbed then the natural life chain will not be balanced. Fish needs and natural balance will be damaged, it can cause serious disasters in the future. The reasons why Sea water is salty.

8. Damage to coral reefs in the sea

Waste can also affect coral reefs in the sea. Damage to reefs is not only caused by humans but also due to pollution. The acidity level of seawater, Ph and so on can damage the development and existence of coral reefs. Coral reefs are one of the important elements for the life of marine animals. If it is damaged, the beauty and preservation of the marine biota will move away and there will be no more place for them to take refuge from predators.

9. Causes disease in animals in the sea

Next is the effects of sewage in the Sea, which causes disease for creatures in the sea. Examples of disability occur both for fish and also other animals. Wastes containing dangerous substances can also cause extinction, large animals such as sharks, whales, dolphins will be endangered. Animals become damaged organs, become injured, disabled and so on. Therefore the impact of waste is quite dangerous if it occurs in frequent time. Shocking facts on how plastics can end up in the Ocean.

10. Can be eaten and become toxic to marine animals

There are several wastes that can be a threat to animal food at sea. Many cases of plastic waste are eaten by large animals such as turtles, whales, sharks and there are still a few others. This is really sad because sea creatures also have the right to live healthily. Harmful human waste is a threat to their lives if left unchecked without precautionary measures.

Apart from the examples and explanations above regarding the effects of sewage in the Sea, here is another example that can be known:

  • Factory waste thrown into the sea contains heavy metals such as mercury, lead, arsenic, chromium, cadmium, zinc, and nickel. All these ingredients cannot be decomposed and will blend into the water. Fish swimming around polluted areas will contain heavy metals in them. And if humans eat polluted fish continuously, it can cause many serious diseases
  • Waste that pollutes the sea usually comes from the beach. Rubbish scattered around the beach will be carried into the sea by tide, so the sea becomes dirty. Non-biodegradable waste such as plastic and carbon can be consumed by fish, and cause the fish to be unhealthy for consumption. Hence water pollution, understanding, causes, and impacts.
  • The condition of the earth began to heat up due to global warming, making the sea no longer able to regulate temperature conditions. The living things most affected by changes in ocean acidity are coral reefs, and fish that depend on coral reefs.

This is the example and also explanation of the effects of sewage in the Sea. Make it insight and also knowledge to preserve the sea for the sake of natural safety in the future.
