Captain Green has to deal with one terrible enemy, plastic pollution. In a lively superhero book where the plot moves at a brisk pace, the author has managed, not only to entertain her reader, but to insert a lot of environmental information. It is mostly about our plastic problem, but it also explain the three Rs: reduce, reuse, and recycle in a very clear way. I think this is one of the better green children’s book for this age group that I’ve read. In 2021 the second book about Captain Green will be published which will have something to do with trees, I think. Definitely an author to keep an eye out for.
