Each year millions of people in the United States
are known to become ill due to food poisoning (food-borne illness) How
ill can you become? Nausea, vomiting, diarrhea, cramps, and fever are
just some of the symptoms that a person can have from food poisoning.
Not very pleasant is it? Health authorities have a saying: "First
you're afraid that you're going to die, then you're afraid your not
going to die." In 1999 the Centers for Disease Control and Prevention
(CDC) estimated that there were over 76 million cases of
gastrointestinal disease including 325,000 hospitalizations and over
5,000 deaths that were directly attributable to food poisoning.

Effects of Oceans on Weather and Climate (9-12)
|
|
|
The oceans cover more than 70% of Earth's surface
and play a major role in regulating the weather and climate of the
planet. Earth's oceans absorb heat from sunlight, hold on to that heat,
and transport it around the globe through the movement of ocean
currents. The motion of the atmosphere, or winds, above it, also
affects the oceans currents. The energy in the wind gets transferred to
the ocean at the ocean surface affecting the motion of the water there.
With the use of sensitive instruments we are able to get a better view
of the functioning of our oceans and atmosphere.
