Tech For Good: Solutions to stem space, noise and micro-plastic pollution

Whether it’s outer space or the deep sea, technology is being leveraged to make our human impulse to explore a more sustainable and cleaner proposition. On the latest episode of ‘Tech for Good’, CNN anchor and correspondent Kristie Lu Stout meets the minds behind the technologies battling space, ocean and noise pollution. You’ve heard of microplastics in our seas, but did you know that there are now half a million human-made objects flying around Earth’s orbit? Moriba Jah, a professor at the University of Texas at Austin and self-proclaimed “space environmentalist,” is on a mission to clean up space junk and ensure a future where space exploration is non-polluting. A startup in London is also tackling an unseen issue: tire particles emitted from cars every time they brake or turn a corner, which ultimately make their way into the ocean. It’s the second-largest microplastic pollutant in the ocean, after single-use plastics. Then we meet Gavin McCormick, an entrepreneur, who is leveraging satellite technology to counter greenhouse emissions. Lastly, we explore the invisible pollutant of noise, an excess of which is proven to be deleterious to mental and physical health, and meet the minds behind technology aimed at reducing noise pollution.
