Explanation: 

Detailed explanation-1: -The most visible impacts of plastic debris are the ingestion, suffocation and entanglement of hundreds of marine species. Marine wildlife such as seabirds, whales, fish and turtles mistake plastic waste for prey; most then die of starvation as their stomachs become filled with plastic.

Detailed explanation-2: -Over a few decades, humans have managed to dump tons upon tons of garbage into the ocean. Of the most devastating elements of this pollution is that plastics takes thousands of years to decay. As a result, fish and wildlife are becoming intoxicated.

Detailed explanation-3: -Toxic Chemicals in Plastic These include endocrine disrupting chemicals (EDCs), which are linked to infertility, obesity, diabetes, prostate or breast cancer, among others. Other health conditions linked to additives include reproductive, growth, and cognitive impairment and neurodevelopment disorders.

Detailed explanation-4: -It is estimated that up to 13 million metric tons of plastic ends up in the ocean each year-the equivalent of a rubbish or garbage truck load’s worth every minute. Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and drowning.

Detailed explanation-5: -Marine Debris Overview Marine debris can injure or kill marine and coastal wildlife; damage and degrade habitats; interfere with navigational safety; cause economic loss to fishing and maritime industries; degrade the quality of life in coastal communities; and threaten human health and safety.
