I'm trying to remember the title of an illustrated children's book I read years ago.
The story features a race of efficient people who put everything into their technology. They build machines, build vehicles, and work all the time. I think the phrase "quickly and well" is repeated throughout the story, as in "they built the ramps quickly and well." Their natural environment is completely destroyed, but they ignore it. Over time they evolve wheels in place of their feet, and pollution-masks in place of their faces. Eventually, their pollution spreads out across space, and some sort of superhero from beyond Neptune (and possibly his dog) detects the pollution and comes to change things.
I think the book is from late 1970s or early 1980s. I think it's printed like a comic book: about 48 8.5" x 11" pages, printed on heavy glossy paper, and possibly done in a two-color process (red and black on white). The art was very simple and stylized. It might be a Canadian publication.
