Plastic pollution is an ever-growing and alarming issue affecting our ocean today. 8 million tons of plastic enter the ocean every year, equivalent to one truckload per minute. Plastic in the ocean can travel far and wide, even reaching remote places like Antarctica and Mariana Trench.
Plastic waste harms marine life by being mistaken for food. Plastic production leads to ocean pollution and harms our planet’s inhabitants.
Changing our attitude towards plastic can greatly reduce its impact on water. We can use reusable or biodegradable materials to fight plastic pollution, recycle more efficiently, reduce consumption, and educate consumers. In this article, we want to dive deeply into this matter.
The Impact Of Plastic On Marine Life
The impact of plastic waste on marine life is significant and far-reaching. In addition to the physical entanglement of animals in ghost gear, plastic lodged in the oceans can be ingested by marine wildlife up the food chain.
Seabirds, turtles, whales, and even tiny polyps in corals mistake plastic particles for plankton or other prey as they appear similar in color and shape.
When these animals consume the plastic, it can result in serious injuries, infections, or blockages which can cause fatality. Not only does this mean too much death of individual organisms, but also a disruption to entire ecosystems as whole species are wiped out by consuming contaminated food sources.
| Harmful Effects of Plastic on Marine Life | Details |
|---|---|
| Ingestion | Marine animals mistake plastic debris for food, leading to blockages in the digestive system, malnutrition, internal injuries, and suffocation. |
| Entanglement | Marine animals, such as turtles and seabirds, can become entangled in plastic waste, causing injuries, amputations, infections, and death. |
| Chemical Pollution | Plastics contain toxic chemicals that can leach into the water, affecting marine organisms’ reproductive systems, growth, and health. |
| Habitat Destruction | Plastic waste can damage and smother critical habitats like coral reefs and seagrass beds, disrupting ecosystems and leading to a loss of biodiversity. |
| Microplastics | Plastic breaks down into tiny particles called microplastics, which marine organisms ingest, potentially impacting the entire food chain. |
Why Is Plastic So Harmful To Marine Life?
Plastic is harmful to marine life for several reasons:
- Ingestion: Marine animals often mistake plastic debris for food. This can lead to serious health issues and even death. Plastic ingestion can cause blockages in the digestive system, preventing animals from properly digesting food and absorbing nutrients. It can also lead to malnutrition, internal injuries, and suffocation.
- Entanglement: Many marine animals, including turtles, seals, and seabirds, can become entangled in plastic waste, such as fishing nets, plastic bags, and six-pack rings. This entanglement can result in injuries, amputations, infections, and death. The trapped animals may be unable to swim, find food, or escape predators.
- Chemical Pollution: Plastics contain harmful chemicals, such as bisphenol A (BPA) and phthalates, which can leach into the water. These chemicals can be toxic to marine life, affecting their reproductive systems, growth, and overall health. Additionally, plastic is a magnet for other pollutants in the water, increasing the concentration of toxins in marine habitats.
- Habitat Destruction: Plastic waste in marine environments can smother and damage coral reefs, seagrass beds, and other critical habitats. Plastic debris can disrupt the natural balance of these ecosystems, leading to a decline in biodiversity and the loss of important breeding and feeding grounds for marine species.
- Microplastics: Plastic does not biodegrade; instead, it breaks down into smaller fragments called microplastics. These tiny particles, often invisible to the naked eye, are pervasive in marine ecosystems. Marine organisms, including plankton, filter feeders, and shellfish, mistake microplastics for food, which can then enter the food chain. This means that even the smallest marine organisms can be affected, with potential consequences for the entire marine food web, including humans who consume seafood.
To mitigate the harm caused by plastic to marine life, it is crucial to reduce plastic consumption, properly dispose of plastic waste, and promote recycling and using biodegradable alternatives.
Adopting sustainable practices and supporting initiatives to reduce plastic pollution can help protect our oceans and the diverse marine life they sustain.
How Does Plastic Destroy Marine Habitats?
Plastic can destroy marine habitats in several ways:
- Physical Damage: Large plastic debris, such as discarded fishing nets, ropes, and bags, can smother and damage marine habitats like coral reefs, seagrass beds, and rocky outcrops. These habitats provide essential shelter, breeding grounds, and food sources for many marine species. When plastic waste covers these habitats, it prevents sunlight from reaching the organisms beneath, inhibiting photosynthesis and affecting the growth and survival of marine plants and animals.
- Chemical Leaching: Plastics contain harmful chemicals, such as bisphenol A (BPA) and phthalates, which can leach into the water. When plastic debris is present in marine habitats, these chemicals can contaminate the surrounding water, affecting the water quality and posing a threat to the organisms that rely on it. These toxic chemicals can disrupt marine life’s reproductive systems, growth, and health.
- Altered Ecosystem Dynamics: Plastic pollution can disrupt marine ecosystems’ natural balance and functioning. It can create physical barriers and alter the water flow, affecting the distribution of nutrients and food sources. This disruption can lead to changes in species composition, reduced biodiversity, and imbalances in predator-prey relationships. Additionally, introducing non-native species through plastic debris can further destabilize ecosystems.
- Habitat Fragmentation: When plastic waste accumulates and forms barriers or floating islands, it can fragment habitats and restrict the movement of marine organisms. Species that rely on migrations, such as fish and marine mammals, may encounter difficulties navigating these barriers, limiting access to essential habitats and resources. This fragmentation can have long-lasting impacts on the connectivity and resilience of marine ecosystems.
- Indirect Effects on Food Chains: Plastics, especially microplastics, can be ingested by smaller organisms at the base of the food chain, such as plankton and filter feeders. As these organisms consume plastic particles, they may suffer from reduced feeding efficiency, impaired growth, and increased mortality. This can have cascading effects on higher trophic levels, impacting the entire food chain and potentially leading to population declines of marine species.
It is crucial to address plastic pollution and its impact on marine habitats through concerted efforts to reduce plastic consumption, improve waste management practices, and promote sustainable alternatives. Protecting and restoring marine habitats are essential for maintaining healthy and thriving marine ecosystems.
Where Does All Those Plastic Come From?
Although plastic has become an invaluable part of modern life, its production and disposal are not without consequences. Globally, more than 300 million tons of plastic waste are produced yearly, which only continues to rise. Of this staggering total, shockingly, only 9% has been recycled; the rest is either incinerated or discarded, often ending up in landfills.
A major factor contributing to this excessive waste is the prevalence of single-use plastics such as straws, carrier bags, and water bottles.
These items are designed to be used for a very short time before they’re thrown away – easily adding to the amount of waste entering landfills and inevitably polluting our environment through over-fill or leakage. It’s estimated that more than 8 million tons of plastic are in our oceans yearly. It’s time to rethink our consumption habits if we want meaningful change.
