Problem 3
Explain why there are no scientific "laws" to explain the structure and function of ecosystems.

Many natural phenomena are highly variable, particularly ones that are biological or ecological. What are the implications of this variability for understanding and predicting the causes and consequences of environmental changes? How do environmental scientists cope with this challenge of a variable natural world?
