Explanations
Travis explains how killing off one animal from the past can change the entire future. If one mouse dies, it can lead to the death of a fox, then a lion, then a caveman who will starve because he couldn't hunt a tiger, and that will lead to a nonexistent human civilization. -
Red Paint
Lesperance explains how they don't alter the future by killing the dinosaurs because he keeps track of their habits, routines, and life span long before the kill and marks them with red paint. If they didn't kill of the creature, it would have already died a few minutes later by a tree or drown in a tar pit. -
