Drinking Water and Society

The course of world society in the twenty-first century is likely to be substantially influenced by a single resource: drinking water. The first and most obvious fact is that water is an absolute necessity. Without water, life—animal, plant, or human—cannot exist. Water comprises approximately 75 percent of the human body. Without adequate water, the body ceases to function. Depending on one’s exertion level and weather conditions, the average adult should consume a minimum of eight 8-ounce glasses (or about 2 liters) of water daily.

One might think that drinking water should not be a problem in the twenty-first century, but it can be. Several related factors define the challenges. First, quantities of water on planet Earth suitable for drinking are extremely limited. Less than 1 percent of all water on Earth is available as groundwater and surface water suitable for human uses such as drinking and cooking. The remainder is either salt water (97 percent) or is locked up in ice (just over 2 percent).  Read more

Facts and figures about water and demographic drivers

  • The world’s population is growing by about 80 million people a year, implying increased freshwater demand of about 64 billion cubic metres a year.
  • An estimated 90% of the 3 billion people who are expected to be added to the population by 2050 will be in developing countries, many in regions where the current population does not have sustainable access to safe drinking water and adequate sanitation. Read more

Oceanography, Biological

Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

Biological oceanographers study all forms of life in the oceans, from microscopic plants and animals to fish and whales. In addition, biological oceanographers examine all forms of oceanic processes that involve living organisms. These include processes that occur at molecular scales, such as photosynthesis , respiration, and cycling of essential nutrients , to largescale processes such as effects of ocean currents on marine productivity.  Read more

Water from the Tree of Life – Enjoy the health benefits of coconut water

The purest liquid second only to water, coconut water is a very potent source of electrolytes, calcium, potassium, magnesium, and natural sugar. A single cup of coconut water contains more than 600 milligrams of potassium and 40 mg of magnesium, making it a top source of both of these important minerals.

Did you know that athletes and people who exercise regularly are encouraged to drink coconut water? As an isotonic solution, coconut water replaces the fluids and minerals that the body loses during physical activities. It can be thought of as nature`s sports drink. Read more

Ice Cores and Ancient Climatic Conditions

In polar and alpine regions that are sufficiently cold, snowfall can persist from year to year and consequently can build up in layers. With time, the weight of the snow compresses the deeper snow layers to form solid ice, resulting in a sheet of ice and snow called a glacier.

Each layer of snow, which eventually becomes a layer of ice, carries with it some information about the environment and climate that existed when the snowfall occurred. By drilling down into glaciers and removing long cores of this layered ice and snow, scientists can better understand how Earth’s climate has changed over time. Read more
