WATER WARS Water is our past. Water is our future. Without it, we cannot survive, and there are no alternatives. Many people have likened the issue of water scarcity to our current economic struggle over petroleum. Without petroleum, we cannot drive our cars, and we may have to walk to school or work. This is not the case for water, as we are not interested in the issue of sustaining life itself. Unfortunately, water scarcity is in the household of our near future. This means that, similarly, petroleum

Oink! Oink! I rotated my four year old head. Searching the mexican crowd for signs of the source. As I rested my hand on the rough red bricks. I noticed a tall man torturing a pig.

The pig hoofs brought up clouds of dust making it hard to see. Sometimes missing the ground and falling on its face. A split second later

What is homeostasis? Homeostasis is the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. (McGraw-Hill) How does the body maintain homeostatic balance? Each organ system helps in some way to maintain homeostasis. However, the organ systems also work together to maintain a constant internal environment. There are seven organ systems (Integumentary, Musculoskeletal, Endocrine, Cardiovascular, Lymphatic, Respiratory, and Nervous) within

Aridity Aridity Causes of Aridity (1) – Atmospheric Pressure (on graph) Causes of Aridity (2) – Cold Ocean Currents: Several deserts lying along western coasts of continents owe their formation to cold ocean surface currents. Air blowing towards the shore, chilled by contact with cold water, produces a layer of fog. This heavy fog drifts onto land. Although humidity is high, the atmospheric pressure that normally causes rainfall is not present. A coastal desert may be almost totally rainless
