 The original "Man After Man" concept, mankind destroying an established ecosystem, was later used by Dixon for another project where mankind colonized an alien planet with a complex and unique ecosystem.This project, published as the book "Greenworld" in 2010 (though so far only released in Japan) follows human colonization of the planet Greenworld over the course of a thousand years, showing how mankind affects its ecosystem.Like its predecessors "After Man" and "The New Dinosaurs", "Man After Man" received generally positive reviews, though the science of the book was criticised in a greater extent than that featured in the preceding works.
