Plastic pollution is a significant threat to the ocean and the marine species that inhabit it. However, some scientists argue that it may be better not to remove plastic from the seas. Why is this the case?
How Plastic Pollutes the Ocean
Due to its inefficiency in degrading naturally, plastic poses a serious ecological problem for several reasons:
- Degradability (resists natural decomposition, taking hundreds of years to fully degrade)
- Massive usage and ubiquity (most daily products and items contain plastic)
- Poor waste management or neglect (there is no effective system for collecting and recycling plastic waste; many items end up in nature)
- Microplastics (particles smaller than 5 millimeters are found in large quantities in the ocean and are ingested by marine organisms)
- Impact on marine flora and fauna (causes serious injuries, digestive issues, and fatalities due to suffocation or poisoning).
To combat plastic pollution in the oceans, it is critical to reduce its production and promote reusable plastic materials, even though these cannot be completely recycled at the end of their lifecycle (discover the percentage of plastic that has actually been recycled since 1950).

Why Do Some Scientists Believe We Shouldn’t Remove Plastic from the Oceans?
A small group of researchers contends that cleaning the oceans could endanger certain marine species that have adapted to plastic… The dilemma is significant.
While plastic disrupts the food chain for many species, scientists involved in the study have demonstrated that other organisms, such as the neuston*, owe their proliferation to it. These organisms, which dwell on the water’s surface, seem to have adapted well to pollution, including species like the sea dragon Glaucus and the snail Janthina.
*Neuston refers to all organisms associated with the water’s surface, at the interface between water and the atmosphere (including algae, mollusks, and cnidarians).
We can observe a massive quantity of neuston on the well-known 7th continent of waste, where this mass of microplastic particles evolves rapidly with the waves in the Pacific. Some biologists warn that cleaning the oceans might jeopardize this group of species. Rebecca Helm, an American ecologist, boldly states:
Some ocean cleanup projects could rob the world of an entire ecosystem we don’t understand and may never be able to recover.

In conclusion, plastic pollution is a severe problem for the ocean and its inhabitants, representing a significant ecological challenge. Plastic, which resists natural degradation, invades our oceans due to its widespread use and poor waste management. Microplastics, in particular, create serious issues for marine life, leading to injuries, digestive problems, and even death.
Nevertheless, some scientists are presenting a fascinating dilemma: removing plastic from the oceans could potentially harm marine species that have adapted to this polluted environment. Neuston, a collective of organisms that live at the ocean’s surface, seem to thrive in the presence of plastic; species like the Glaucus sea dragon and Janthina snails have found niches within these conditions.
The 7th continent of garbage, a vast accumulation of microplastic particles, has evolved into a habitat for these organisms. Biologists like Rebecca Helm caution that ocean cleanup initiatives could destroy a unique ecosystem that is not yet fully understood.
This situation presents a complex dilemma: should we clean up the oceans at the risk of disrupting ecosystems that have adapted, or should we leave the plastic undisturbed, risking harm to other species and the overall health of oceanic environments? This debate highlights the necessity for further research to identify balanced solutions that safeguard both the environment and marine biodiversity.
The Plastic Pollution Predicament: Cleansing our Oceans or Protecting Marine Ecosystems?
How Plastic Pollutes the Ocean
Plastic pollution has emerged as a **major ecological issue** threatening marine biodiversity. Its characteristics make it particularly harmful to ocean health:
- Degradability: Plastic resists natural decomposition and can take hundreds of years to break down completely.
- Massive Utilization: Plastics are present in most everyday products, contributing significantly to environmental pollution.
- Poor Waste Management: Inefficient systems for collecting and recycling plastic result in vast amounts of plastic ending up in nature.
- Microplastics: These tiny plastic particles, measuring less than 5 millimeters, infiltrate marine ecosystems and are ingested by a wide array of marine organisms.
- Impact on Marine Flora and Fauna: The ingestion of plastic can cause severe injuries, digestive problems, and, in some cases, death by suffocation or poisoning.
To combat **plastic pollution** in the world’s oceans, it is crucial to reduce plastic production and promote the use of **reusable materials**. Unfortunately, while such materials are beneficial, they also cannot be fully recycled after their lifecycle (you can discover the percentage of plastic that has been recycled since 1950).
Why Do Some Scientists Think We Shouldn’t Remove Plastic from the Oceans?
A controversial perspective exists: a minority of researchers argue that removing plastic could inadvertently harm certain marine species that have adapted to this pollution. The dilemma poses significant questions for ecologists and conservationists alike.
Plastic disrupts the food chain of many species, yet certain organisms, such as the neuston, appear to have flourished in plastic-dominated environments. For instance, organisms like the Glaucus sea dragon and Janthina snails have developed successful survival strategies amid pollution.
The neuston refers to all organisms that live at the water’s surface, interacting with both the water and the atmosphere (including algae, mollusks, and cnidarians).
Notably, a significant concentration of neuston is reported at the infamous 7th continent of waste, a massive accumulation of plastic waste in the Pacific Ocean. Researchers analyze how cleaning efforts could inadvertently threaten this unique habitat.
Rebecca Helm, an American ecologist, warns:
“Some ocean cleanup projects could rob the world of an entire ecosystem we don’t understand and may never be able to recover.”
The Complex Dilemma: Clean the Oceans or Preserve Adapted Ecosystems?
The debate highlights a profound ethical and ecological dilemma: should marine cleanup efforts be pursued at the risk of destabilizing adapted ecosystems, or should we continue to tolerate the environmental devastation inflicted by plastic waste?
Potential Benefits of Marine Plastic Ecology
Understanding these implications raises fascinating questions about **marine ecology**:
- Could cleaning the oceans destroy an ecosystem that has adapted to utilize plastic waste as a resource?
- Should marine conservation efforts pivot towards managing plastic pollution rather than completely removing it?
- Can hybrid approaches be developed that balance ecosystem preservation with effective pollution management?
Case Studies on Ocean Cleanup Projects
Various cleanup projects have commenced, notably the Ocean Cleanup project aimed at intercepting plastic waste in rivers before it reaches the ocean. The methodology involves:
- Utilizing barriers to catch plastic debris.
- Employing specialized ships to retrieve large amounts of waste.
- Implementing community engagement efforts to raise awareness of pollution.
Examples of Cleanup Efforts
| Project Name | Location | Objective |
|---|---|---|
| Ocean Cleanup | Great Pacific Garbage Patch | Removal of floating plastic debris |
| River Interception | Various river locations | Prevent plastic from entering oceans |
| Plastic Bank | Global | Incentivizing recycling and waste collection |
Practical Tips for Individuals: Reducing Plastic Waste
While large-scale cleanup efforts play a vital role, individuals can also contribute to alleviating plastic pollution:
- Use reusable bags, bottles, and containers.
- Support companies that prioritize sustainable packaging.
- Participate in local clean-up efforts or organize community clean-up days.
- Stay informed about plastic waste initiatives in your area.
The Road Ahead: Balancing Cleanup and Conservation
Ultimately, the challenge of plastic pollution in the oceans requires a multifaceted approach. It’s critical to continue research into the ecological consequences of marine cleanup and observe how affected species respond to changes in their environment. Addressing the challenge is essential for marine conservation, protecting vulnerable ecosystems, and ensuring the health of our planet’s oceans.
