  layer, the appropriate way to avoid additional
  cases of skin cancer would be to provide more
  sunglasses, more hats, and more suntan lotion or
  is there more to it?

Global Warming Debate

• What effect will temperature increases have on
  human beings and the natural environment?
• What, if anything, can we do to stop global
  warming?
• What are the costs associated with either an
  increase in temperature, or human intervention to
  halt it?

What are the causes of Global Warming?

• Substances in the air which pose a potential
  threat to human health and/or the environment.
• The presence of particles in the air which
  decreases visibility.
• The U.S. EPA estimates that 50 of the US
  population is exposed to air pollutants exceeding
  current federal standards.

15
Has the industrial revolution produced
advancements that will ultimately ruin the very
world we have sought to improve?

• Automobiles, other transportation devices
  produce
• Carbon dioxide, nitrogen and sulfur oxides,
  products of incomplete combustion
• Increases in greenhouse gases, acidic
  precipitation.

16
Effects of Air Pollution

• Rising sea level
• Change of precipitation local climate
  conditions acid rain
• Alterations of forests crop yields
• Expansion of deserts into existing rangelands
• More intense rainstorms
• Not all long-term effects can be determined.

Is this normal?
18
What can we do?

• Solar Energy

Wind Power
Biomass
Geothermal

Human destiny is bound to remain a gamble,
because at some unpredictable time and in some
