Sustainability and the future of our world
- Human population growth exacerbates all environmental problems
- The growth rate has slowed, but we still add more than 200,000 people to the
planet each day
The Nature of Science
-Science:
- A systematic process for learning about the world and testing our understanding
of it
- A dynamic process of observation, testing, and discovery
- The accumulated body of knowledge that results from this process
- Science is essential for
- Sorting fact from fiction
- Developing solutions to the problems we face
Science: Critically Examining Evidence
- Some scientists design tests: ideas supported by evidence
- Explanations must:
- Be testable
- Resist repeated attempts to disprove it
- Accepted ideas can be applied in policy, management and legal decisions (e.g. adding
dispersants to oil spills)
The Scientific Method
- Assumptions:
- The universe works according to unchanging natural laws
- Nature is Lawful, not random
- Behavior is Determined, and not due to free will
- The laws of nature are Understandable (although often very complicated!)
- A technique for testing ideas with observations
- Events arise from causes, and cause other events
- We use our senses and reason to understand nature’s laws
Observations -> Questions -> Hypothesis -> Predictions -> Test -> Results (Fail to reject
hypothesis -> Predictions)(Reject hypothesis -> Hypothesis)
Choosing an Article
- Pick area of interest
- Textbook or the “Environmental News” link on Sakai for ideas
- Peer Reviewed
