How is Plastic Ruining The Oceans In The Worst Way Possible?

Plastic has become an integral part of our daily life. From furniture to grocery bags, vehicle parts to toys, plastic is an unavoidable element available in various forms.

According to a study, a single plastic particle can absorb one million times more toxic chemicals than the water surrounding it.

Plastic isn’t biodegradable, accentuating the threat of lingering plastic for years and generations.

According to estimates, people worldwide throw away almost four million tons of trash daily, of which 12.8% is plastic, polluting land, air and water.

While plastic thrown into landfills contaminates the soil and groundwater with harmful chemicals and microorganisms, the marine pollution caused by plastic is immeasurable.

Just like on land, even in marine areas, the effects of plastic on marine life have started to be felt. The studies reveal that around 10 million tonnes of plastic waste are washed into the ocean annually.

The United Nations Environment Programme estimates there could already be as many as 51 trillion microplastic particles in the oceans.

While some of the plastic waste in the oceans comes from land, predominantly due to mismanaged waste disposal, the ships and offshore oil and gas platforms also contribute to it.

In recent times, considering the increase in the disposal of plastic in the ocean, it has become imperative to take all possible measures to combat this problem by understanding the consequences of plastic in the sea.

But before one can do so, one must understand the repercussions of plastic in the sea, which is necessary to take protective measures even more sensibly.

Among all the threats to the marine environment, the threat from plastic is one of the most dangerous ones.

Some of the ruinations of the oceanic domain caused by plastic waste can be explained as follows:

Garbage in the ocean – namely plastic – jeopardises the natural ambience of marine life. It disrupts the entire bio-geo cycle, causing unwanted problems to the marine ecosystem. Plastic from microfibers and microbeads released from wash-off products and cosmetics like face wash and toothpaste is also extremely harmful to aquatic flora and fauna.

Plastic threatens life underwater in several ways, from smaller fishes to massive mammals and amphibians. Reports say that around one million seabirds and 100,000 marine mammals are killed every due to plastic ingestion. Unfortunately, several marine species are on the verge of extinction because of such ocean pollution.

Consumption of plastic by sea creatures causes severe digestive problems, mainly untreated. Many sea animals eat plastic, mistaking it for food. It decreases the capacity of their stomachs, causing starvation. Reports suggest that plastic consumption by all types of fish amounts to several tons yearly. In addition to causing intestinal injury and death of these fish, this also spreads the risk across the food chain to bigger fish and marine mammals.

According to scientists, coral reefs that come into contact with plastic trash have an 89 per cent chance of contracting a disease.

Sea turtles are the other unfortunate victims of ocean plastics apart from fish. Like fish and other marine beings, Sea turtles consume plastic litter as food, leading to a blockage in the gut, ulceration, and eventually death. Studies have found that half of the sea turtles worldwide have ingested plastic.

Sea turtles and seals are the most common victims of ‘Ghost Nets’ in the ocean. Like plastic bags, bottles, or other junk, fishing gear, fishing nets, and plastic crates also cause oceanic ruination. These plastic wastes harm marine life by choking life forms and also entanglement.

These nets are known as ghost nets or ghost gear, while the process of marine creatures tangled in them is called ‘Ghost Fishing.’ Regarding the stray plastic crates, a reference was made to a plastic crate choking a penguin in the movie “Happy Feet.”

Plastic waste in the oceans also threatens the lives of birds and other beings that depend on the oceanic life forms for their food requirements. Most of the time, these beings suffer because of ingesting plastic or suffocation, especially birds, by merely being tricked by the brighter colours of plastic junk.

The birds also often get caught in the debris and die due to suffocation. According to several research studies, 44% of all seabird species, along with cetaceans, oysters, mussels, corals, and sea turtles, have been documented to have plastic debris in or around their bodies.

Plastic pollution in the seas affects human beings in different ways. In addition to the risks from polluted marine waters, ingestion of plastic by fish and other aquatic beings also, in turn, causes harm to people who consume marine food. Plastic contains a lot of substances which might otherwise be hazardous.

When fishing activities are carried out, there is every chance that fish infected with such harmful substances might find their way into our households, causing health problems to the end consumers. Studies have found that toxins in plastics cause several health issues, including cancers, immune system problems, and congenital disabilities.

The amount of garbage in the seas also pollutes the oceanic waters, and plastic harms marine life in several ways. Disposing of hazardous materials, including toxic substances such as Bisphenol A, commonly found in many plastic commodities, pollutes the water badly.

Since Bisphenol A isn’t diluted in water, it results in grave environmental problems. Similarly, debris uses oxygen as it degrades, resulting in a low oxygen level in the seas. As oxygen levels go down, they badly affect the survival of marine animals, including whales, dolphins, and penguins.

The ruination of the ocean doesn’t only include the high seas. It also consists of the shores and beaches infested with plastic. The plastic waste can float for miles on the water, be submerged on the seabed, or be commonly found on the seashore.

Such congested areas become easy threats to birds and other land animals caught in the chokehold of plastic. Irrespective of the location, the ecosystem gets hugely impaired because of such marine debris.

Ocean garbage in the form of plastic also leads to the invasion of non-indigenous species and organisms in naturally occurring marine colonies, thus posing a threat to the functioning of ecosystems. The billions of micro-plastic particles floating in the ocean are all potential carriers of non-indigenous invasive species.

Oceanic currents, particularly gyres, sometimes accumulate plastic within their spiral and concentrate in different ocean areas. The Great Pacific Garbage Patch, located in the North Pacific Ocean off the coast of California, is an example of such marine debris.

Researchers say this is the world’s largest ocean garbage site, and this floating garbage site is almost twice the size of Texas. Learn how the Ocean Cleanup system will be fighting this.

Plastic in the sea is a result of human callousness. Since annual plastic consumption has increased globally, plastic waste in the waters has also increased drastically.

In addition to the ill effects on the marine ecosystem, plastic pollution also negatively impacts the economy as it affects sectors such as tourism, fisheries, and aquaculture.

However, many efforts are underway to reduce plastic pollution in the seas, including cleaning up beaches and waterbodies and preventing the entry of plastic into the ocean in the first place. Many organisations are fighting to save the oceans.

Countries should discourage using single-use plastics like plastic straws, food wrappers, plastic bottles, and bottle caps, which are disposed of after use. Instead, one should opt for large-scale plastic recycling to prevent our planet from being littered with tons of plastic. As our world is grappling with global warming and climate change, we must change our lifestyle and limit our consumption to safeguard our earth.

Many countries have restricted or banned several plastic products to battle plastic pollution, particularly in the ocean. Enumerable sewage treatment efforts worldwide and increasing awareness about the negative impacts of plastic could help us retain our oceans.

  1. Anish, I would think this article is getting more popular! Do you have a more concise list of the particular problems that plastics pose to the oceans? Just a simple, but pretty complete list is all I’m looking for. Definitions can be separate or linked.

    Thanks for putting the info out there! We are working on creating more compostables and composting in the world and want to see single-use plastic eliminated and ensure that we stop the flow of plastics into the environment.

  2. We should rise up against the Conservatives. Climate change is a threat. I should be in school but instead I am here. YOU HAVE RUINED MY CHILDHOOD!!!

  3. This is a great article about plastic in the ocean it tells me everything I wanna know about the plastic in the ocean.

  4. Naturally as an artist using marineplasticdebris , at this stage we can only do beachcombing pickups thus reducing further photodegration into microplastics.

  5. Very helpful and Informative….thankyou for sharing and good luck for further more good work…. looking forward

  6. Are you familiar with www. washedashore. org we make art from some of the marine debris that washes up on Oregon. Our goal is to run out of our craft materials, but don’t see that happening for a long time.
