The Atmospheric Radiation Measurement Program is a key contributor
to global climate change research. With facilities in three
locations around the world, ARM studies cloud formation and
radiative feedback in the atmosphere. Through continuous field
measurements ARM provides data necessary for development of
accurate climate models.

The domestic daily water use of three families in different geographical locations in the world are shown. Different areas in the world together with the standard of life determine to a great extent how much water is available per household. Water is used from daily necessity to liquid extravagance, from simple chores to full-tilt recreation. Namibia is the only country in the world that purifies sewage water in a way that makes it potable, and then distributes it to consumers. Water is used in a spiritual role in different religious cultures, purification, baptism and cremation.

Explores the lives of farmers across the globe to see how water is managed and/or mismanaged. While irrigation seems to be the key to successful agriculture, it does however have severe drawbacks, such as over exploitation of existing fresh water reservoirs. There are industries that need huge amounts of water in their production process: paper, steel and beer. A Japanese steel company is leading the industry in its water conservation and environmental policies. A modern beer industry in Bangkok, Thailand uses water conservation and wastewater reduction techniques.

Planet earth has launched an all out scientific assault on Mars. On the frontline, two NASA rovers began crawling across the surface of Mars, a planet once thought to be frozen and sterile. High above, Europe's Mars Express gazed down from orbit with a roving eye and an arsenal of high tech detectors. All three were scouting for evidence of one simple earthly ingredient - water. Find proof that water had once flowed across the dusty Red Planet, and the hunt for Martians - dead or alive - could begin in earnest.

Potential conflicts are brewing between the nations that share the Nile River Basin. The days of the Nile only nourishing Egypt's great demand for water might be rapidly coming to an end. Sudan, Ethiopia and Uganda are geographically located in the larger Nile basin and control the sources of the river. In recent years they have been demanding a greater share of the Nile's precious resource as demand comes closer to overtaking this finite supply. All 13 countries with access will have to come to agreements on how to share the Nile. Will this be the cause of the next war?
