Carol Emshwiller's "No Time Like the Present" (short story, butterfly effect, free)

A light general read about "we" vs "them" - a town has received a lot of racially different-looking & wealthy immigrants recently, & we see the reactions of natives to newcomers. In between, we keep seeing hints of a couple of much hashed genre themes - environmental dystopia & butterfly effect.

1. Ray Bradbury's "A Sound of Thunder" (download text/MP3): Story that invented "butterfly effect". Or rather, had someone else coin the phrase based on events in the story. This Emshwiller story makes a specific reference to the Bradbury story ("It’s gotta be even worse than that butterfly back in the Jurassic era.")
