See The Air is one of the best blogs on the Internet on the topics of air quality, pollution and the science and data behind COVID19. The owner of the site, Sotirios, has written three excellent books:
Nicholas - a children's book that raises awareness on the issue of pollution and air quality.
Nicholas, the Science Book - a follow up to the successful Nicholas children's book.
See the Air - a wealth of knowledge of the impact of air pollution on our health and how to mitigate it.
