What is resource?
  • (From Wikipedia)
  • Resource may refer to
  • Resource (economics), commodities and human
    resources used in the production of goods and
    services, including
  • Natural resource, a commodity that is valuable in
    its relatively natural form.
  • Human resources (HR) or human capital, valuable
    human work power.
  • Resource (project management), economic resources
    used in planning of tasks. (not relevant to our
    discussion)

  • Resource is
  • Anything that is both naturally occurring and of
    use to humans.
  • Examples of resources include water, soil, air,
    oil, mineral, vegetation including wood, plants
    or animals as food.

7
Competition for resources
  • Like any resources, many environmental resources
    are limited in nature. (e.g. crude oil)
  • Living organisms including humans usually compete
    for limited resources. (e.g. animals competing
    for food and water)
  • Competition for resources is a known mechanism
    for evolution.

8
Environmental Resources Management
  • Environmental crisis may result if environmental
    resources are not managed sustainably. (i.e.
    sustainable resource management)
  • E.g. Forestry, fresh water, fisheries

9
Utilization of environmental resources
  • Extraction, utilization and depletion of
    resources are often linked to environmental
    issues.
  • Can you list some examples?
