Explanation:

In the book "A Sound of Thunder" Travis worked for a time machine and believes that balance between the past and the future is by discussing how small changes can have big consequences.

He said that nothing should be touched that if for example, a mouse is killed, it ultimately affects other rats and the fox that might have eaten the rat. Also, the lion that may have eaten the fox is also affected. He believed that change will bring about a greater change in the future.

Everything is vital and changing one thing will affect others. Nothing is small, everything matters and all have a role to play.
