What is Air Pollution?
Air pollution is the modification of the natural characteristics of the atmosphere by a chemical
particulate matter. Also, it is a mixture of solid particles and gasses in the air.
Usually when people think about pollution we think smog and acid rain, CFC's and other
forms of outdoor pollution. But did you know that air pollution happens inside homes and
other buildings!!!!!
What is water pollution?
Water pollution is a large set of adverse effects upon water bodies such as lakes,
rivers, oceans and groundwater caused by human activities.
Although some kinds of water pollution can occur through natural processes, it is mostly a
result of human activities. We use water daily in our homes and industries, about 150 gallons
per day, per person in the U.S. Some sources of water pollution are direct and indirect
contaminant sources. Direct sources include effluent outfalls from factories, refineries, waste
treatment plants etc.. that emit fluids of varying quality directly into urban water supplies.
Indirect sources include contaminants that enter the water supply from soils/groundwater systems
and from the atmosphere via rain water.
Global Warming
The deadline for deciding whether to list the big white bears as threatened under the Endangered
Species Act is Wednesday but Dale Hall, head of the Fish and Wildlife Service, told reporters it
would take as much as a month more to analyze all the information. This is the first time global
warming has been a factor in proposing threatened status for any U.S. species, Hall said, and
and that has added to the complexity of the decision.
