The Effects of Improper Waste Disposal on Marine Life: Why Does it Matter and How can We Prevent It?
AI summary Read the abstract
This review outlined how improperly disposed plastic waste enters the ocean, breaks into microplastics that harbor toxicants like BPA and POPs, and harms marine life from sea turtles to filter feeders, with cascading effects on food safety and human health.
Improperly disposed of waste, specifically plastic, can end up in the ocean and negatively impact marine life, and in turn, negatively impact human health. Marine life, such as turtles, have faced serious health consequences and even death from entanglement in abandoned fishing gear and consuming plastics. Larger plastic particles can break down into smaller particles known as microplastics which can harbor harmful substances (such as Bisphenol A and persistent organic pollutants) and can cause several negative health effects when consumed by marine life such as loss of nutrition, starvation, and death. Microplastics have been found in 75% of commercial fish. The chemicals that microplastics harbor could accumulate and be magnified in higher levels of the food chain, which often includes the fish that humans consume. The consequences of microplastics on human health have not been well researched, but the particles have been found in a human placenta, indicating that microplastics can translocate through humans like they translocate in fish. Taking action to reduce the number of plastics in our oceans through plastic bag bans, recycling, and organizations like the ocean cleanup, is an important step in protecting the health of marine and human life. More research must be done on the topic of microplastics to truly understand its effects on human health as it could have current or future consequences that are unknown.

Marine plastic pollution: ecological risks, environmental distribution, and sustainable mitigation perspectives
AI summary Read the abstract
This review pulls together existing research on how plastic waste, from big debris down to tiny microplastics, is building up in our oceans and harming marine life through ingestion, toxic exposure, and habitat damage. This matters for people too, since contaminated seafood and disrupted ecosystems can affect food safety and public health. The authors stress that better waste management and global cooperation are needed to fix it.
Effects of marine microplastic on marine life and the food webs – A detailed review
AI summary Read the abstract
This review provides a comprehensive look at microplastic pollution in marine environments, covering sources, impacts on marine life, and risks to human health through the seafood supply chain. Microplastics cause physical harm like gut blockages in marine animals and can carry toxic chemicals that accumulate up the food chain. The authors emphasize that with global plastic production still rising, urgent policy action and better waste management are needed to protect both ocean ecosystems and human health.

This review summarizes how millions of tons of plastic waste enter the oceans each year and break into microplastics that absorb pollutants, heavy metals, and chemical additives. These contaminated particles pose risks to human health when they enter the food chain through seafood consumption.
Microplastics in our oceans and marine health
AI summary Read the abstract
This general review examined the scale of microplastic ocean contamination and its risks to marine life and human health, covering ingestion pathways, food web transfer, and the current regulatory landscape. The authors argue that public education, plastic use reduction, and stronger waste governance are essential to preventing further marine contamination.
The Effects of Plastic and Microplastic Waste on the Marine Environment and the Ocean
AI summary Read the abstract
This review summarizes the scale of plastic pollution in the world's oceans, where nearly 280 million tons of plastic are produced annually and much of it ends up in marine environments, affecting at least 267 species. Microplastics enter the marine food chain when sea creatures ingest them, ultimately reaching humans through seafood consumption, with potential health consequences that add to the economic and ecological damage.
