## Marine Ecosystem Impacts and Biodiversity Threats

Direct Wildlife Impact Evidence:

Marine plastic pollution affects over 800 species through ingestion, entanglement, and habitat destruction, with sea turtles mistaking plastic bags for jellyfish, seabirds feeding plastic debris to their chicks, and marine mammals becoming entangled in fishing nets and packaging materials that cause injury, starvation, and death.

Research documents that 90% of seabirds have plastic in their stomachs, compared to 5% in the 1960s, demonstrating the dramatic increase in marine plastic contamination over the past five decades and its accelerating impact on avian populations.

Large marine species including whales, dolphins, and sea turtles face particular risks from plastic ingestion, with autopsy studies revealing stomach blockages from accumulated plastic debris that prevent normal feeding and digestion, leading to malnutrition and death.

Microplastic Contamination and Food Chain Impacts:

Microplastics smaller than 5mm diameter have infiltrated marine food webs at all levels, from zooplankton to apex predators, creating bioaccumulation pathways that concentrate plastic particles and associated toxins as they move up trophic levels.

Scientific studies detect microplastics in commercial fish species consumed by humans, including tuna, salmon, and shellfish, with potential implications for human health though long-term effects remain under investigation by health authorities worldwide.

Marine microplastics act as vectors for persistent organic pollutants (POPs) including PCBs and DDT, concentrating these toxic compounds at levels up to 10,000 times higher than surrounding seawater and transferring them to organisms that ingest contaminated plastic particles.

Habitat Degradation and Ecosystem Disruption:

Plastic pollution alters marine habitats by covering seafloor surfaces, reducing light penetration in water columns, and creating artificial surfaces that disrupt natural ecosystem processes and species interactions.

Coral reefs face increased disease susceptibility when exposed to plastic pollution, with studies showing 89% disease likelihood for plastic-contact corals compared to 4% for plastic-free corals, threatening already vulnerable reef ecosystems.

Coastal ecosystems suffer from plastic accumulation that smothers marine vegetation, blocks drainage systems, and creates breeding grounds for disease vectors, affecting both marine life and human communities dependent on coastal resources.
