ENV100Y5- Lecture 1- Introduction
Definition of Environment:
Biotic (living things)
Animals, plants, forests, soils, etc.
Abiotic (non-living things)
Continents, rocks, papers, clouds etc.
Our built environment
Roads, buildings, factories etc.
Social relationships and institutions
Governments, universities, religions, cultures etc.
Difference between environmental science and environmentalism:
Environmental science
Pursuit of knowledge about the natural world
How the natural world works
How nature resources and processes support life (human and other)
How human activities affect the environment
Scientists try to remain objective
A social movement dedicated to protect the natural world
Interdisciplinary nature of environmental science:
Environmental science requires many disciplines such as geology, ecology, ethics and
many more in order to deal with environmental problems for example, needing experts to
manage a large oil spill near a beach.
Environment encompasses biotic, abiotic, built, and social/cultural environments, and the
interactions that involve them.
Science informs our attempts to solve and prevent problems.
Environmental science helps us understand how the environment works and our
relationship with the environment.
Environmental science is necessarily interdisciplinary.
In this course, all of these concepts are reflected.

ENV100Y5- Lecture 2- Introduction to Environmental Science
What is Science and how does it work?
A systematic process for learning about the world and testing our understanding of it.
The accumulated body of knowledge that arises from this dynamic process.
The Scientific method: (what is it?)
Testing ideas through observation, questioning and experimentation
Idea that the universe works according to natural law
Events arise from causes, and cause other events.
We use logic, systematic testing, and our senses to understand natural law
The Scientific method: (key element of science)
Make observations and ask questions.
Formulate hypotheses (explanations)
Use hypotheses to generate predictions (specific statements that can be tested)
Interpret test results (support or reject hypothesis)
The Scientific method is part of a larger process
The process includes peer review, publication and debates
Uncertainty is a fundamental part of the scientific process
A consistently supported hypothesis becomes a theory
ENV100Y5- Lecture 3- Introduction to Environmental Science (Continuation)
People differ in their perception of environmental problems:
Interdisciplinary communication is difficult
Communications about environmental issues is further complicated by differences in
language and worldview
Perception is influenced by worldviews:
Policy/Legal/Government vs. Scientific
Academic vs. Applied
Profane/Secular vs. Religious/Sacred
Affluence vs. Poverty
Industrialized vs. Developing Nations
Anthropocentric vs. Ecocentric
Ecosphere vs. Technosphere
Economy vs. Ecology
