Only a 12-year-old girl can save the planet. She devised a way to remove microplastics from the ocean and the sea



Anna Du attends only the 7th grade at Massachusetts Elementary School and can already enjoy great success. He managed to build a robot that could identify microplastic at sea. They are a problem not only for marine animals but for the entire ecosystem. Scientists raise a warning finger and say that by 2050 more fish than fish will swim in the sea, which is really alarming.

This is one of the reasons why Anna decided not to look at everything. She noticed that it was extremely difficult to remove the special microplastics that are deposited on the bottom of the ocean. That's why he created a robot that is just right for this activity. The robot is reminiscent of a small vehicle made of PVC pipes and fishing weights that moves in the sea and is capable of identifying microplastics by infrared radiation.

How is it possible that a 12 year old girl does something like this? She acquired all the knowledge she needed in her local library and watched videos on IouTube. But she was interested in the science of early childhood, and her parents were involved in various events when Ana was only five years old.

Many experts surrendered to the girl, including Casey Machao from the Oceanographic Institute Voods Hole. For The Smithsonian, she said that although the device looks simple, Anna deserves praise. She set up a functional prototype that would help solve a serious human problem.

Casei Machao is dedicated to collecting and evaluating data from the polar regions and is pleased that one of the robots that participated in her work inspired Anu to create his own prototype. Her robot even took part in the Broadcom Masters competition, and Anna set him up with an idea in the top 30 contestants.

The competition was attended by many experts and the best engineers and scientists in the field assessed the ideas. Although Ana did not win the first prize, she has no head and hope to become an engineer once for a while to help create things that will make the world a little better.
