From the earliest life forms to life on earth as we know it today, water has been the one essential constant . Covering roughly seventy percent of the earth’s surface, only a mere fraction is available as freshwater and of that, an even smaller proportion is available for human use and we are only just beginning to truly understand the nature of this most precious and limited resource. In addition to its life sustaining role, water is also one of the most destructive forces on earth, carving breath taking gorges and valleys, yet disasters related to water are responsible for large scale loss of life as well. In its different forms water supports ocean life, retains precious atmospheric samples dating back thousands of years, is a muse for writers, artists, and sculptors, as it tenuously supports a human population of six billion and growing.

Lubbock Lake Landmark Last Updated on 2014-08-19 16:59:46
The Lubbock Lake National Historic and State Archeological Park, known locally as the Lubbock Lake Landmark, is an archeological and natural history preserve located in Lubbock, Texas, USA. The 300 acre preserve is located in Yellowhouse Draw, an intermittent tributary of the Brazos River. This reserve, which is managed by the Museum of Texas Tech University, is important because it contains evidence of nearly 12,000 years of use by humans as well as records of now extinct species that formerly lived in this area. It is one of the few places in North America known to have a complete record of human existence from the Paleo-Indian culture all the way through the Archaic, ceramic, and Prehistoric cultures.
Lubbock Lake Landmark received its name from a reservoir that was created in the 1930s. This area housed a natural spring fed lake until the spring began to... More »
National Oceanic and Atmospheric Administration (NOAA), United StatesLast Updated on 2014-06-30 19:00:15
The National Oceanic and Atmospheric Administration (NOAA) is a federal agency within the United States Department of Commerce. As a science-based operational agency tasked with monitoring climate and changes in the environment, NOAA is responsible for the study of the atmosphere and the oceans. The agency issues daily weather forecasts and storm warnings, restores coastline, aids the flow of marine commerce, and manages fisheries. NOAA's activities facilitate weather- and climate-sensitive economic activity that account for roughly one-third of the country's gross domestic product (GDP). The agency also responds to natural and man-made maritime disasters, operates a complex network of oceanographic, meteorological and atmospheric data-collecting products and services, and manages marine mammals, marine endangered...

PollutionLast Updated on 2014-06-28 18:51:13Pollution is environmental contamination that results in harm or death to living organisms. Most pollution is in the form of chemical additions to air, water or soil; however, in modern times starting in the mid-twentieth century noise and light have been considered as pollution sources. Most pollution is man-made, with natural fluctuations in atmospheric composition, surface water bodies and soil considered temporal gyrations in the Earth's natural history. The chief driver of pollution is the massive growth in human population, which induces the proximate causes of intensive agriculture and extraordinary industrial output. The United Nations and the Blacksmith Institute are two prominent organisations that tabulate locales of the greatest pollution intensity; while their listings do not correspond precisely, the overlap countries that both entities agree are the worst polluted...

Tug of water: an economic perspective on water and the environmentLast Updated on 2014-06-28 17:29:44As economies expand globally, the strain on the earth’s natural resources becomes increasingly apparent, and perhaps one of the most pertinent issues facing us today is that of water scarcity. Hitherto widely perceived as a free good, the demand for water now outstrips supply over much of the earth’s surface. Indeed, the International Water Management Institute estimates that one third of the world’s population face some form of water scarcity, either due to lack of investment in water supply (or inequitable distribution) or due to physical scarcity, where there is not enough water to meet demands. It is the latter situation that is most pertinent in terms of impacts on our natural capital. In these areas, increasing demand for water means that aquatic and other water-dependent ecosystems are threatened by the abstraction or pollution of the flows that are required to... More »
Backyard pondLast Updated on 2014-06-25 17:01:23
A pond or water garden will likely become the focal point for all your backyard conservation.
Backyard ponds and water gardens are for birds, butterflies, frogs, fish, and you and your family. These ponds are typically small, sometimes no larger than 3 to 4 feet in diameter. They may be built in barrels or other patio containers. Water is effective in drawing wildlife to your backyard. It is also a natural, relaxing, and scenic addition that can provide interest and enjoyment.
Consider locating your backyard pond where you can see it from a deck or patio. Have it blend in with its natural surroundings. Elevate the soil around the pond slightly so that excess water will flow away from the pond, not into it. Make sure that any drainage from the pond is away from your house. Plan to landscape around the pond to provide habitat for frogs and birds that need land and water.... More »
