Marine food chain will be influenced by plastic products

Earlier, biologists have found remains in the whales, sea turtles and other large marine body Plastic products . The study found that due to plankton wrong eating marine litter, causing the digestive system is blocked, and as a major food source for marine life, marine litter can not be decomposed marine organisms into the body , affecting the marine food chain.
Scientists first discovered copepod plankton would devour plastic particles, they mainly feed on algae, chemical and tactile sensors cannot distinguish the food is eaten. Video data captured display, copepods biological paddling leg toward the microscopic level of polystyrene microspheres swim, and swallowed them, these polystyrene microspheres gradually deposited in their bodies.

When a large plastic garbage into the marine environment, wildlife and this will have serious implications for the ecosystem. Scientists assessment shows that every year about 800 tons of plastic is poured into the sea, fishing nets and plastic bags for some large marine life brings threats to survival.
However, even after these plastic garbage decomposition, still constitute a hazard to the marine environment. Plymouth Marine Laboratory researcher Matthew – Cole (Matthew Cole) Dr. depth study of the marine ecosystem , ” miniature plastic ” , study pointed out that until now miniature plastic substances harmful plankton still being ignored. The study, published in “Environmental Science and Technology” magazine recently published.

Plankton is an important part of the marine food chain, it is located at the bottom of the food chain, is a lot of marine life food source. As more and more marine litter, increasing the likelihood of plankton eating plastic material. Marine debris plastic plankton will have a negative impact, followed by a further impact on the marine food chain. We must accelerate the pace of polystyrene recycling to protect the environment.
