Environmental Science
the use of scientific approaches to understand the complex systems in which we live. It is the systematic study of our environment and our place in it
The scientific method
an orderly approach to asking questions, collecting observations, and interpreting those observations to find an answer to a question.
Quantitative reasoning
understanding how to compare numbers and interpret graphs, to perceive what they show about problems that matter.
Uncertainty
we know there are limits to our knowledge. Understanding how much we don’t know, ironically, can improve or confidence in what we do.
Ecosystem services
- services or resources** provided by *_environmental systems (nature, not humans) -_ often ignored, but they support all our economic activities, nature doeesn’t put a price on them.
- provisioning of resources, such as the fuel we burn
- *supporting service**
- water purification,
- production of food and atmospheric oxygen by plants
- decomposing of waste by fungi and bacteria
regulating services
- maintenance of temperatures suitable for life by the earth’s atmosphere and carbon capture by green plants - which maintains a stable atmospheric composition.
cultural services - nonmaterial benefits (recreation, aesthetic, etc)
Critical and analytical thinking
the practice of stepping back to examine what you think and why you think it
or why someone believes a particular idea
acknowledging uncertainty is one part of critical thinking.
Sustainability

Biggest 3 problems

The Flint Water Crisis (Lake Huron and Detroit River)

PIPES - were installed in 1901-1920 and they contained LEAD - they did not treat the water for coming into conatct with lead pipes -> LEAD POISONING for Flint’s population.
- Air Quality

Empiricism
We can learn about the world by careful observation of empirical (real, observable) phenomena;
we can expect to understand fundamental processes and natural laws by observation.
Uniformitarianism
Basic patteerns and processes are uniform across time and space;
the forces at work today are the same as those that shaped the world in the past, and they will continue to do so in the future
Parsimony
When 2 plausible explanations are reasonable, the simpler (more parsimonious) one is preferable.
