18+ Best Sea Pollution Facts: You Need to Know

Sea Pollution refers to pollutants and trash that come from land sources and end up in the sea. This pollution results in widespread damage to sea life and to economic structures that depend on the infrastructure of the sea. 

Sea pollution occurs when agricultural, residential, and industrial wastes, excess carbon dioxide, particles, or invasive organisms enter the ocean and create harmful effects.

Thus, sea pollution may happen in many ways and eventually be really dangerous to marine animals. Hence, the entire oceanic ecosystem is threatened by different sources of pollution. 

So, in this article, we will explore some really amazing facts about sea pollution.

Facts About Sea Pollution

Plastic Waste Is A Big Reason:

Plastic is the most common component that is found in the seas. It harms the environment as it cannot be broken down easily and is sometimes mistaken for food by sea animals. 

Plastic waste in the seas may need hundreds of years to degrade, resulting in a buildup of plastic pollution that can harm marine life and ecosystems.

As plastic cannot degrade, it can break down into smaller pieces, known as microplastic, due to wave action and sun exposure. Then it can enter our ecosystem’s food chain and never disappears.

Plastic Garbage Is Increasing In The Ocean:

At least 8 million tons of plastic garbage enter the oceans every year. That is similar to emptying a garbage truck of harmful plastic into the sea every minute.

By the year 2050, it is estimated that there will be more plastic in the sea than fish by weight. Plastic pollution can even lead to the death of marine animals that ingest or become entangled in plastic waste.

The Oceans Contain A Lot of Plastic Debris:

There is so much waste at sea that debris has created a few giant garbage patches. The term “garbage patch” is mainly an area of debris ranging in size from microplastic debris to large bundles of derelict fishing gear and some other collected marine debris.

Large, rotating sea currents create these huge patches called gyres that usually pull plastic debris into one location, mainly to the gyre’s center. These debris-forming garbage patches can be seen from the surface of the sea all the way to the sea floor.

There are five great garbage patches:

There are five really huge garbage patches in the ocean. The largest of which is the Great Pacific Garbage Patch. The others are two in the Atlantic Ocean, one in the Indian Ocean, and another in the Pacific Ocean.

Almost 100,000 marine mammals and one million seabirds die yearly due to plastic pollution. Over 50 percent of the animals known as sea turtles have consumed plastic.

There is a lot of plastic in the ocean:

There is a lot more plastic in the ocean than the number of stars in a milky way.

Plastic waste or debris can absorb dangerous and toxic chemicals from ocean pollution and eventually poisons whatever it is. It poses a significant health threat to different sea creatures and the entire marine ecosystem.

The Largest Garbage Patch Is Larger than Texas In Size:

Among the five gyres of garbage patches in the ocean, the Great Pacific Garbage Patch is approximately twice the size of Texas. The gyre, known as the North Pacific Gyre off the coast of California, mainly contains an estimated 1.8 trillion pieces of harmful debris.

There, the number of floating pieces of plastic outnumbers the total ocean life by six to one in the immediate area.

Countries That Contribute A Lot To Sea Pollution:

Plastic in the ocean comes from China and Indonesia more than anywhere else. Also, they are responsible for one-third of plastic pollution. 80% of plastics contributing to sea pollution come from just 20 countries, including the United States.

Moreover, plastic is the most significant source of pollution in the ocean. When plastic materials start to degrade, which is almost 400 years for most plastic, the procedure mainly releases chemicals that further contaminate the sea.

Great Barrier Reef Is Under Threat:

The Great Barrier Reef, one of the significant marine ecosystems of the world, is under threat from sea pollution. This pollution includes plastic waste and coral bleaching caused by rising sea temperatures.

Most Coral Reefs, which are noteworthy habitats for various types of marine species, are also threatened by sea pollution and other human activities.

More than One Million Seabirds Are Killed:

More than one million seabirds are killed by ocean pollution each year. Three hundred thousand porpoises and dolphins die yearly from being entangled in discarded fishing nets and other items. 

In addition, one hundred thousand sea mammals are killed in the sea by pollution each year.

Land-Based Sources Also Pollute The Ocean:

Another important source of pollution in the sea is directly from land-based sources, like dirt, oil, farms, septic tanks, motor vehicles, and ranches, among various larger sources. Thousands of land waste and trash are dumped into the sea daily.

Even though most of the waste and trash dumped into the ocean is released hundreds of miles away from the land, it still eventually washes up on coastal areas and beaches, affecting everything in between.

Every marine animal or creature is affected by the chemicals created by men and then released into the water.

Oil Is A Significant Cause Of Sea Pollution:

Oil is another significant sea pollutant. Oil is one of the fastest sources of deterioration to the sea, being a lot more dangerous than waste and trash.

However, only a small percentage of oil, around 12%, is dumped into the sea, resulting from actual oil spills. The most amount of oil causing harm in the sea is a result of drainage from the land.

Oil Spills Can Suffocate Marine Creatures:

Oil spills can suffocate marine life to death. Also, this can lead to behavioral changes and also a breakdown in the thermal insulation of those animals that can survive.

It can even change the entire ecosystem of an affected area, like a deep ocean or a long coastline.

Microfibers Can Be Harmful To Sea Creatures:

Microfibers can even cause a lot of sea pollution. With each load of human laundry, more than 700,000 synthetic microfibers are washed into the waterways.

Unlike natural fibers, like wool or cotton, these synthetic microfibers can make up as much as 85 percent of all beach trash that usually does not break down.

Toxic metals are also dangerous:

Different types of toxic metals can destroy behavior, biochemistry, growth, and also reproduction in marine life.

Chemical pollutants such as heavy metals and pesticides can accumulate in the ocean and harm marine life. Moreover, harmful fertilizers from agricultural waste harm marine life to a great extent.

Ships may harm marine life:

Shipping and other maritime industries also pollute the ocean through different activities, such as dumping waste in the sea and ballast water discharge.

Overfishing and destructive fishing practices can also result in declining marine populations and eventually disrupt marine ecosystems.

Littering Plays A Vital Role In Sea Pollution:

Littering can also cause pollution in the sea, which can result in a substantial loss of life beneath the seas. In fact, billions of tons of litter generally end up in the seas yearly, with more than 250 million tons of debris generated.

This has resulted in a gradual loss of marine life and an increase in endangered animals and creatures.

Radioactive Waste Is Also A Significant Sea Pollutant:

Not all ocean pollutants come from trash, oil, and other solid wastes. Dumping radioactive waste from different nuclear reactors drained sewage, and the industrial race is also a heavy contributor to sea pollution.

Excessive Noise Is Also Harmful:

There is also a lot of noise in the ocean. The creation of noise pollution can take place through shipping and military activities. These activities can cause cellular damage to specific invertebrates, including anemones and jellyfish. 

These sea creatures are a significant food source for bigger sea animals like sharks, tunas, sea turtles, and many more.

So, we can say that the ocean and its creatures cannot thrive as a dumpsite for people. We must take major steps to address this issue, known as sea pollution, and offer ourselves a healthy and pollution-free life. To know more, you can visit our website.
