Environment: the total of our

  • All the things around us with whichsurroundings

we interact:

  • Living things ( biotic )
    • animals, plants, forests, fungi, etc.
  • Nonliving things ( abiotic )
    • continents, oceans, clouds, soil, rocks
  • Our built environment
    • buildings, human-created living centers

Humans and the world around us

  • We depend completely on the environment for

survival

  • wealth, health, mobility, leisure time
  • but natural systems have been degraded
  • i.e., pollution, erosion and species extinction
  • Environmental science is the study of:
  • how the natural world works
  • how the environment affects humans and vice-versa

Global human population growth

  • 7.033 billion humans (passed 7B in April, just 5 months ago)
  • Why so many?
    • Agricultural revolution
      • stable food supplies
    • Industrial revolution
      • urbanized society powered by fossil fuels
      • sanitation, medicine, more food

Thomas Malthus and human population

  • Thomas Malthus
    • population growth must be restricted…or it will outstrip food production - starvation, war, disease

The “ecological footprint”

  • The environmental

impact of a person or

population

  • humans have surpassed the Earth’s capacity

Ecological footprints are not all

equal

  • The ecological

footprints of countries

vary greatly

  • the U.S. footprint almost 5 times greater than world’s average
  • developing countries have much smaller footprints than 15 developed countries docsity.com

Environmental science ≠ environmentalism

  • Environmental science…
    • pursuit of knowledge about the natural world
    • scientists remain objective
  • Environmentalism…
    • social movement dedicated to protecting the natural world
    • resort to extremes

• Science : The nature of science

  • systematic process for learning about the world and testing our understanding of it - observation and testing
  • accumulated body of knowledge is a result
  • Science is important
  • sort fact from fiction
  • develop solutions to the problems

The scientific method•Makes observations… asks questions

of some phenomenon

  • Formulates a hypothesis
    • statement that attempts to explain the scientific question
  • Hypothesis used to generate predictions
    • specific statements that can be directly tested.
  • Results either support or reject the hypothesis

The scientific process is part of a larger process

  • The scientific process includes peer review , publication , and debate
  • A consistently supported hypothesis becomes a theory
    • a well-tested and widely accepted explanation
  • With enough data, a paradigm shift can occur
    • a change in the dominant view
