# Forest example for complex system
A forest is a good analogy to understand the Observer effect may impact a complex system.
A complex system is defined a such:
- Dynamic connections
- Animals, trees, plants all need each other to live.
- Entangled causes and effects
- Chopping one tree may not grind the forest from a halt, and you may have an unforeseen consequences elsewhere.
- Fuzzy boundaries
- What does the boundary of a forest end?
- Unpredictable patterns
- It's hard to guess what will happen next. One part of forest has lots of tall trees, another has more bushes. A forest may change in an unexpected way.
