SYMPTOMS
  • Global climate change
  • Rising average temperatures
  • Rising sea level
  • Melting polar ice
  • Warming oceans
  • Rising use of fossil fuels appetite for oil
    increasing

3
SYMPTOMS
  • Loss of two billion tons of topsoil each year due
    to wind and water erosion
  • Washing into mouths of rivers causing dead
    zones

4
SYMPTOMS
  • Polluted water and air
  • Synthetic (man-made) chemicals ending up in
    atmosphere and hydrosphere

5
SYMPTOMS
  • Diminishing biodiversity
  • Worldwide habitat destruction
  • Ecosystems in danger
  • Colony-Collapse Disorder

6
SYMPTOMS
  • Destruction of tropical rain forests and marine
    ecosystems
  • More forest fires in the temperate zone

7
SYMPTOMS
  • Destruction of worlds coral reefs
  • Bleaching of polyps due to increased solar
    radiation warmer water
  • Killed when fishermen use explosives cyanide to
    kill fish

8
SYMPTOMS
  • Amphibians on the decline more deformities
  • Frogs, toads, salamanders disappearing world-wide
  • In danger now
  • 12 of 10,000 bird species
  • 24 of 4,763 mammal species
  • 30 of 25,000 fish species

9
SYMPTOMS
  • Collapse of most of the worlds oceanic fisheries
  • Populations of tuna, groupers and cod are
    plummeting.
  • We are spending our savings of ocean food
    resources.

  • More destructive storms due to rising
    temperatures
  • Hurricanes more frequent violent
  • Frequency of severe storms also increasing
  • Tornadoes out-of-season

15
SYMPTOMS
  • Deteriorating range lands
  • Support worlds 3.3 billion cattle, sheep and
    goats
  • Half of grasslands moderately degraded

16
SYMPTOMS
  • Disappearing species
  • Have had five great extinctions so far
  • Now in early stages of 6th
  • Loss of species is weakening the web of life.

17
DIAGNOSIS
  • People-itis!

18
PEOPLE-ITIS
