Navigating the nexus: climate dynamics and microplastics pollution in coastal ecosystems

Area of Science:

• Environmental Science
• Marine Biology
• Public Health

Background:

• Microplastic (MP) pollution is a growing global concern, entering ecosystems and food chains, posing risks to environmental and human health.
• Coastal areas are particularly vulnerable due to the complex interplay of climate dynamics, pollution sources, and ecosystem health.
• Human activities, including improper waste disposal, are primary contributors to microplastic contamination in marine environments.

Purpose of the Study:

• To provide a holistic understanding of the interconnected factors shaping coastal ecosystems.
• To synthesize current research on climate change impacts, microplastic pathways, and pollution effects on coastal regions.
• To highlight the cascading health and socio-economic consequences of coastal pollution.

Main Methods:

• Comprehensive literature review synthesizing interdisciplinary research.
• Analysis of climate pattern changes and their influence on microplastic prevalence.
• Exploration of pathways for microplastic infiltration into marine environments.

Main Results:

• Climate change significantly increases microplastic prevalence in coastal regions, accelerating their spread and ecosystem deterioration.
• Rising sea levels, ocean acidification, and extreme weather events contribute to habitat loss, biodiversity decline, and economic repercussions.
• Feedback mechanisms intensify pollution impacts, underscoring the need for environmental conservation.

Conclusions:

• Climate change and microplastic pollution create a synergistic threat to coastal ecosystems and human well-being.
• Innovative strategies, including remote sensing, AI monitoring, bioremediation, and global policy cooperation, are essential.
• Addressing the complex interactions between human activities, industry, and biodiversity is critical for sustainable coastal management.
