In "A Sound of Thunder," Ray Bradbury presents a future society in which time travel is possible. In order to prevent any altering of future events by visiting the past, precautions are taken. Time Safari, Inc, the company that runs dinosaur hunting safaris, takes strict measures not to affect anything in the past that may have an impact on the future.
The first precaution that they take is that everyone participating in the safari must not step off of the anti-gravity path that they have installed. This is to ensure that not one blade of grass is disturbed by their presence because the effect could be exponential through time.
The second precaution involves the manner in which they kill the dinosaurs. A preliminary trip is made to identify which dinosaur is about to die. Then, the safari goes back to that exact time and location and kills the dinosaur exactly when and where it would have died naturally. This allows all the same bacteria and scavengers to access the carcass as it did millions of years ago. The bullets are even removed from the dinosaur so nothing new is introduced into the process.
The third precaution is that no trophies are allowed to be taken back to the present time. This is, again, so the dinosaurs decompose the same way they did millions of years ago avoiding a ripple effect through time. The safari participants are only allowed to take home a picture of themselves with their kill.
