About 18 million tons of plastic enter the ocean annually, putting marine life at a life-and-death test
Statistics show that approximately 18 million tons of plastic flow into the oceans each year, severely threatening marine ecosystems (sources: UNEP, Ocean Blue Project, GVI, Condor Ferries, Frontiers in, Our World in Data). This plastic includes large debris, microplastics, and discarded fishing gear, causing multiple harms to marine life.
Staggering numbers of seabird and marine animal deaths
About 1 million seabirds die annually from plastic ingestion or misfeeding. Studies indicate that currently about one-third of seabirds contain plastic in their bodies, and by 2050 this figure could rise to 99% (sources: Wikipedia, Ocean Blue Project, Pew Environment).
Additionally, around 100,000 marine animals—including whales, sea turtles, seals, etc.—die each year due to plastic entanglement or ingestion, and this number continues to rise.
How does plastic kill?
Ingestion: Many marine animals mistake plastic bags and films for food like jellyfish. Plastic blocks their stomachs, preventing feeding, leading to malnutrition or starvation. Seabirds frequently swallow plastic fragments and feed them to their chicks, causing high chick mortality.
Entanglement: Ghost fishing gear such as abandoned nets and ropes in the ocean still trap fish, seals, turtles, and other animals, causing suffocation, limb loss, or death from blood loss.
Internal damage: Plastic fragments entering organisms cause chronic inflammation and tissue damage. Some studies even found pathological features similar to Alzheimer’s disease in the brains of some seabird chicks (source: The Guardian).
Ecological crisis faced by wildlife
Species Threatened: Over 700 endangered or threatened species are affected by plastic pollution, including flagship species like the Hawaiian monk seal and Pacific loggerhead turtle (sources: Ocean Blue Project, Biodiversity Center, UNEP).
Ecosystem Imbalance: Plastic pollution not only affects individual survival but also disrupts reproduction, migration, and habitat behaviors. For example, seabirds mistakenly feed plastic to their chicks, greatly reducing chick survival rates and hindering population renewal.

Background Perspective
Global annual plastic production is about 390 million tons, with roughly 18 million tons entering the oceans. Plastic waste accounts for 80% of global marine debris. Among this, discarded fishing gear makes up two-thirds of large marine plastic debris.
Urgent Challenges
Mass deaths of seabirds, sea turtles, and whales caused by plastic pollution are not only ecological issues but are deeply impacting fishery resources, coastal tourism economies, and even the international food chain. The spreading plastic crisis is hindering sustainable development plans in coastal nations.
