Why are models important in environmental science?
Modeling is an important component of all environmental work at EPA. It helps inform both decisions and policies. Models improve the understanding of natural systems and how they react to changing conditions, such as exposure to hazardous substances and the temporal and dose effects from the exposure.
When did environmental degradation start?

What are the four models used in environmental science?
A formal representation of the behavior of system processes, often in mathematical or statistical terms. The basis can also be physical or conceptual.” The types of the environmental models used by the EPA include fate and transport models, emissions and activities models, exposure models, and impact models.
Why do we study environmental history?
The principal goal of environmental history is to deepen our understanding of how humans has been affected by the natural environment in the past and also how they have affected that environment and with what results.
What is the importance of environmental philosophy?
