Things I didn't learn because they 'didn't have enough time to talk about it in the video': the environmental aspects of harvesting this sand. I am amused when YouTube video presenters claim they didn't have enough time in their film to include a key important aspect. In the days of broadcast TV programmes would have a fixed time slot and some content might have to be edited out or not covered. Rarely did any presenters say 'not enough time' though. But on YouTube where there is 'plenty of time' and a video does not have to be a particular length, people do claim 'not enough time', to make you watch ~10 minutes to learn nothing much beyond how you must like and subscribe to their channel.
