* TakeThat: Perhaps as a counterpoint to the post-GlobalWarming scenario of the Greg Mendel books, Hamilton seemingly constructed Earth of Fallen Dragon for a single, hilarious joke on the [[PoliticalCorrectnessGoneMad politically correct]]. In the interests of efficiency and profit, the {{Mega Corp}}s which rule Earth have developed open-source fusion technology and nutritious, palatable [[FutureFoodIsArtificial artificial food]]. Result; zero emissions, no animal cruelty, and most of the landscape is GhibliHills. This means that the only people who still practice animal husbandry are countercultural types. After reaching Earth, Lawrence starts a relationship with a feisty hippie, and thoroughly enjoys the acrobatic sex. However, when she takes him home to meet her parents, things start to bug him; the air stinks, the house is cold and uncomfortable, and then the GranolaGirl tells him that not only is the sandwich he's eating made with "real beef" but that she ''slaughtered the cow herself'' - which causes him to throw up and run right back to the nice, clean, comfortable city where people don't drink contaminated water and eat rotting food.
