Only a 12-year-old girl can save the planet. She invented a way to remove microplastics from oceans and seas


Anna Du attends only 7th grade at Massachusetts Primary School and can already enjoy great success. He was able to build a robot that can identify microplastics in the sea. They pose a problem not only for marine animals but for the whole ecosystem. Scientists are raising a finger of warning and say that by 2050, more fish than fish will swim in the seas, which is really alarming.

That's one of the reasons why Anna decided not just to look at all of this. She noted that it is extremely difficult to remove especially the micro-plastics that are deposited on the bottom of the ocean. Therefore, he created a robot that is precisely suitable for this activity. The robot resembles a small vehicle made of PVC pipes and fishing weights that move in the sea and is able to identify microplastics using infrared radiation.

How is it possible for a 12-year-old to do something like that? She gained all the necessary knowledge in her local library and watched hours of videos on YouTube. But she had been interested in science since childhood, and her parents were involved in various events when Anna was only five years old.

Many experts surrendered to the girl, including Casey Machao of the Woods Hole Oceanographic Institute. For The Smithsonian, she said that although the device appears to be simple, Anna deserves praise. She set up a functional prototype to help solve the grave problem of humanity.

Casey Machao is dedicated to collecting and evaluating data from polar regions, and is delighted that one of the robots involved in her work has inspired Anna to create her own prototype. Her robot even participated in the Broadcom Masters competition, and Anna put it with the idea among the 30 best competitors.

The competition was attended by many qualified people and ideas were evaluated by the best engineers and scientists in the area. Although Anna did not win the first prize, she has no head and hopes to become an engineer from time to time to help build things that will make the world a little better.
