Plankton in the ocean depends on eating plastic for a living

[China Jiuzhi Plastics Network] A long time ago, people found residual plastic products in the digestive tract of sea turtles, seabirds and whales. Recent research shows that marine debris can block the micro-plankton digestive system. However, these plankton are the food sources of many large marine organisms.
For the first time, scientists have discovered that copepoed plankton swallows plastic particles, which usually feed on algae. The video data showed that the copepod creature swam the legs toward the microscopic grade of polystyrene microspheres and swallowed them into the body. These polystyrene microspheres will gradually deposit in the copepod plankton. . Usually, copepods mainly feed on algae, which use chemical and tactile receptors to distinguish which foods are edible and which ones are not.
The results of this study are thought-provoking, and a large amount of plastic waste enters the marine environment, which will have a serious impact on wildlife and ecosystems. Scientists report that about 8 million tons of plastics are dumped into the ocean each year, and fishing nets and plastic bags pose a threat to the survival of some large marine life.
However, even after the plastic waste is decomposed, the decomposition of a large number of plastic bags into debris still poses a hazard to the marine environment. Dr. Matthew Cole, a researcher at the Plymouth Marine Laboratory in the UK, has studied the marine ecosystem “micro-plastics” and wrote a research report that until now the micro-plastics were still neglected for plankton. The study was published in the recently published journal Environmental Science and Technology. Cole and colleagues found that at least 13 species of plankton can swallow polystyrene microspheres of different sizes, including important marine larvae such as crabs and oysters. They also found that the tiny plastic material adhered to the upper part of the planktonic organism and the attached body.
Cole pointed out that adding micro-plastic materials to the copepod spurs of natural algae can show that they gradually reduce the amount of algae intake. Our research report suggests that marine micro-plastic debris will have a negative impact on plankton function and health. Plankton is an important part of the marine food chain and is the food source for most large filter-feeding organisms and many crustaceans.
