A report claims that Chinese scientists have created a robot fish to help eliminate microplastics in the oceans.
Plastics can be absorbed by the devices, including microscopic pieces of plastic, paint and straws. Plastics smaller than grains of rice are found in almost all fish species and have made it up the food chain until they reach humans.
“It is of great significance to develop a robot to accurately collect and sample detrimental microplastic pollutants from the aquatic environment,”The Guardian was told by Yuyan Wang (a researcher at Sichuan University’s Polymer Research Institute) that he is one of the leading authors of this study. “To the best of our knowledge, this is the first example of such soft robots.”

They are just one-half inches long and propelled using a light laser system. “heal”If they are damaged in the process of eating plastics from the ocean, then they will be responsible.
Guardian called it the “fish” “bionic,”Chemically bond to the microplastics with antibiotics, dyes and heavy metallics.
The robot fish is a prototype and will not be used in ocean patrols. The robot fish can also only move on the surface. However, they plan to develop a version capable of going underwater.
“I think nanotechnology holds great promise for trace absorption, collection, and detection of pollutants, improving intervention efficiency while reducing operating costs,” Wang said.
The presence of microplastics has been documented in almost all the oceans, rivers, and lakes on Earth, as well as in Arctic snow. The amount of plastic finding its way into the ocean is expected to triple to 39 million tons per year by 2040 if current trends continue. Plastic is typically 3/8 inches or less in size once it has reached the sea.
An international effort is underway to create a treaty that will stop the pollution of plastics, similar to the Paris climate accord.
Recent research by packaging firm RAJA revealed that India and China both dump nearly 220,000 tons of plastic per year into the ocean. The U.S. ranked eighth with around 2,645 tons, despite being America’s largest plastics manufacturer. The U.S. was not the only country responsible for plastics found in the ocean. Other nations that were more involved include Brazil, Mexico and Thailand.
