I love YouTube as anyone reading this site knows. I especially like it when various people unwittingly produce HS education material. We have all been in training sessions that have some Z list actor and a dodgy script video. These sort of presentations are largely counter productive. In the old days they were accompanied with equally lousy music. Well here is a crash course in pollutants and industry, for free and with an interesting format.
YouTubers have to entertain, there is no revenue without subscribers. This allows a bit of creativity and that engages groups.
I will be the first to suggest that they are not seen as a be all and end all on any issue. I do suggest that they are great for introducing any HS subject.
This one runs through the top 11 ( according to the creators) pollutant threats.
