Bionic robo-fish able to remove microplastics from seas revealed by scientists – video

Scientists have designed a tiny robot fish that is programmed to remove microplastics from seas and oceans by swimming around and adsorbing them. Microplastics are the billions of tiny plastic particles which fragment from bigger plastic things used every day. They are one of the 21st century's biggest environmental problems because once they are dispersed into the environment they are very hard to get rid of, harming the environment and animal and human health.
