A report has been published by scientists explaining their findings that how much garbage is floating in the world's oceans. Over 5 trillion pieces of plastic debris, weighing 269,000 tons are spread worldwide.

It was expected by researchers that they will find out a big amount of microplastics. That is plastics that the sun and waves have broken down into smaller pieces minor and the number of microplastics were an order of magnitude smaller than anticipated. From this latest study, observations of other researchers' have been proved that there is a huge difference between expected and observed microplastic weight and plenty in the world's oceans.

These small pieces of plastic do not decompose easily. Instead fish, turtles and other animals eat these tiny pieces. Also, several of these small pieces have sunk below the surface of the ocean, and also pieces can float in the water column where it is difficult for surveys to reach. There are also chances that they have settled to the bottom where snails and other bottom feeders can consume them.

As animals eat plastic, they also consume all the poison that was used to produce plastic, such as BPA, with all the pollutants in the water that plastics soak up when they float in the ocean. It was shown by the study that the concentration of poisonous chemicals, like PCB and DDT, can be greater up to a million times in plastic remains than found in seawater.

As these chemicals are inherently poisonous, so they can cause serious physiological harm to animals. As big fish consume little fish, more organisms consume plastic particles indirectly by their prey organisms, and concentrate the chemicals up the food chain.
