  • humans their interactions with the environment
  • It examines
  • chemical, physical biological agents that move
    through the environment affecting human health
    investigates ways to control or minimize them.

  • Malnutrition
  • condition in which the body does not get the
    nutrients required for optimal health

Env. Issues - Greenhouse Effect Global Warming
  • Greenhouse effect

    atmosphere absorb reflect infrared rays warm
    Earths surfaces
  • Global warming
  • an increase in earths temperature

Env. Issues Destruction of the Ozone Layer
  • Ozone form of O2
  • Ozone layer protective layer of the upper
    atmosphere that traps ultraviolet (UV) radiation
    from the sun and prevents it from reaching
    earths surface
  • CFCs chlorofluorocarbons group of gases that
    are easy to compress expand / used as a
    propellant in aerosol sprays coolants

Env. Issues Destruction of the Rain Forests
  • Rain forest
  • hot, wet, forested area that contains many
    species of trees, plants, animals 7 of
    earths land
  • Source of food, rubber, timber, ingredients for
    prescription drugs
  • Forests are being cleared for agriculture trees
    produce O2 absorb CO2 and it can kill many
    species of plants animals
