When one crucial part of the system- regardless of its size or seeming insignificance- is tampered with, all latter parts of the system must suffer, because each part relies on the preceding part of the system to occur naturally. Similarly, if a new element were to be introduced into the system, such as a new species of fish, an equal amount of damage could occur.
