The Guardian in England reports that there is a Greta Thunberg Effect--"a boom in books aimed at empowering young people to save the planet." Thunberg is a sixteen-year-old Swedish climate change activist.
I wonder if this Greta Thunberg Effect is only in England, since The Guardian is an English publication. Greta Thunberg is on her way to America as I write this, so we'll see if she makes an impact in childlit here.
Okay, I'm going to admit that I'd only heard of Thunberg because she's one of the women on the cover of the September issue of British Vogue, guest edited by our own duchess, Meghan Markle.
