Detailed explanation-1: -A preliminary study was conducted to assess microplastics in postmortem samples of internal tissues of companion animals. Suspected microplastics were observed in the internal tissues of cats and dogs.

Detailed explanation-2: -Scientists have been finding these plastic bits in all kinds of animals, from tiny crustaceans to birds and whales. Their size is a concern. Small animals low on the food chain eat them. When larger animals feed on the small animals, they can end up also consuming large amounts of plastic.

Detailed explanation-3: -Marine microplastics will affect many aspects of the marine fish and marine food chain. The microplastics can have a toxic effect on fish and other aquatic life, including reducing food intake, delaying growth, causing oxidative damage and abnormal behavior.

Detailed explanation-4: -Most microplastics start their journey on land and are carried by rivers and wind to the ocean, where they are caught in the global ocean circulation system. Microplastics have been found on beaches around the world, even in our protected areas, and have been documented in sea ice in the Arctic and on the ocean floor.
