Plastics in the environment as potential threat to life: an overview
Summary
This overview examined the broad environmental impacts of plastic pollution across oceans, soil, freshwater, and sediments. Researchers highlighted that wildlife including seabirds, fish, and crustaceans are affected by plastic entanglement and pollutants carried by microplastics. The study suggests that plastics can be potentially harmful to humans and other mammals, and emphasizes the need for mitigation strategies.
Plastics have become inevitable for human beings in their daily life. Million tons of plastic waste is entering in oceans, soil, freshwater, and sediments. Invasion of plastics in different ecosystems is causing severe problems to inhabitants. Wild animals such as seabirds, fishes, crustaceans, and other invertebrates are mostly effected by plastic entanglements and organic pollutants absorbed and carried by plastics/microplastics. Plastics can also be potentially harmful to human beings and other mammals. Keeping in view the possible harms of plastics, some mitigation strategies must be adopted which may include the use of bioplastics and some natural polymers such as squid-ring teeth protein. This review focuses on the possible sources of intrusion and fate of plastics in different ecosystems, their potential deleterious effects on wildlife, and the measures that can be taken to minimize and avoid the plastic use.

The Detrimental Impacts of Plastic Pollution on Wildlife
This review examines the harmful effects of plastic pollution on wildlife across marine, coastal, and terrestrial habitats, including entanglement, ingestion, and chemical exposure. Researchers found that over 2,000 species are affected by plastic debris, with microplastics presenting a particular concern because they can accumulate toxic chemicals and enter food chains. The study calls for stronger policy measures and public awareness to reduce plastic waste and protect biodiversity.
Plastic pollution in the marine environment
This review provides a comprehensive overview of plastic pollution in coastal and marine environments, covering everything from how plastics enter the ocean to their effects on marine life. Researchers compiled global data showing microplastic concentrations ranging widely across different water bodies and sediments, with marine organisms accumulating significant amounts. The study underscores that plastic pollution causes ecological damage through entanglement, ingestion toxicity, and the transport of invasive species.
Plastics - a curse for fauna-over viewing the situation
This review examines the pervasive threat of plastic pollution to fauna across terrestrial, aquatic, and marine environments, noting that roughly 40% of ocean surface is covered with plastic debris with approximately 8 billion tonnes entering annually. The authors survey documented impacts of both macroplastics and microplastics on soil fauna, marine organisms, and wildlife from polar regions to high-altitude environments.
Overview of microplastic pollution and its influence on the health of organisms
This review summarizes microplastic pollution across marine, freshwater, and soil environments and its effects on organisms ranging from plankton to mammals. Microplastics disrupt feeding behavior, trigger oxidative stress, alter gut bacteria, and impair reproduction in exposed species. The authors note that microplastics also enter the human body through food, water, and air, posing potential health risks that require further research.
A Review of Microplastic Pollution: Harmful Effect on Environment and Animals, Remediation Strategies
This review provides a broad overview of microplastic pollution, covering its sources, environmental distribution, and harmful effects on wildlife and ecosystems. Researchers summarize current knowledge about how microplastics enter food chains and interact with other pollutants. The study also evaluates existing cleanup and remediation strategies for addressing microplastic contamination across different environments.
