The climate crisis looms large for young people. We see teenagers like Greta Thunberg inspiring kids around the world to take part in political activism. Then, there are solution-seekers like Fionn Ferreira, an 18 year-old Irish wunderkind, who won the grand prize at the 2019 Google Science Fair for creating a method to remove microplastics from the ocean.

Pretty much everybody already knows about the issue of climate change and the problem of plastics in the ocean, so the writer really doesn’t need to explain much about the problem.

Ferreira's project used a novel, but effective methodology for removing ocean plastics. He used magnets to attract microplastics from water. The project found that a magnetic liquid called ferrofluid attracted the tiny plastic particles and removed them from the water. After nearly a thousand tests, his device successfully removed about 88 percent of the microplastics from water samples, according to The Irish Times.

His idea came to him after finding a rock covered in oil near his remote coastal town in Ireland's southwest. He noticed tiny bits of plastic stuck to the oil. The tiny size of microplastics has befuddled scientists looking for ways to remove them from the environment. But Ferreira thought of something.

Those microplastics, which are less than 5mm long, come from beauty products, various textiles and larger bits of plastic that break down. Since they are so small, they escape water filtration systems and end up polluting waterways. Once in rivers and oceans, marine animals of all sizes end up ingesting them.

Both microplastics and ferrofluids have similar properties, so they attract. For his experiments, shown in this video, Ferreira added ferrofluids to water and then stirred in a solution chock full of microplastics. When the microplastics found the ferrofluids, they adhered together. Ferreira then dipped a magnet to the solution, which attracted the combined ferrofluids and microplastics. It left behind clear water, as CNN reported.

Christopher Sloan (Dec 13 2019 3:14PM) : Anticipating readers' objections more

Probably beyond the scope of such a short article, but the writer doesn’t really bring up topics that would be impediments to the project. For example, there’s no mention of how much this might cost, or how this would work in open water, or how the plastic would then be stored after it was caught by the magnet. Still, it’s a great idea and just in its early stages, so those kinds of issues probably won’t be addressed for a while.
