We turn air into food, so why can’t we get carbon to leave the atmosphere – or helium to stay? In this episode of the podcast Huh? Science Explained, we’re diving into the gassy soup that surrounds Earth, and looking at the substances that stay in our atmosphere, the substances that leave, and the substances that we’d really like to remove.
Huh? Science Explained is a LiSTNR podcast.
