Enter hereMeanwhile, the Environment Ministry, which conducted separate research on Feb. 23 and 24, said Tuesday it found that nutrient salts necessary for the growth of seaweed had plunged in quantity to almost undetectable levels almost throughout the inland sea.The ministry also said in a report that quantities of ''''chlorophyll a'''' -- a substance in photo plankton -- in many of the 24 points surveyed in the sea were unusually high. Photo plankton consume nutrient salts.In one area deep inside the bay, the ministry detected 20 micrograms of the substance per liter -- almost matching concentrations found during times of so-called red tides caused by massive outbreaks of photo plankton. A microgram is one-millionth of a gram. The panel also recommended the farm ministry open the gates after taking measures to ensure that seawater flowing back into the dike does not cause damage to local residents living near the tideland.Agriculture, Forestry and Fisheries Ministry officials said they will have to carefully weigh the timing of the gate opening since the panel recommended that measures be taken to prevent the inflow of seawater from stirring sludge accumulated at the bottom of the reservoir and thus inflicting damage to the entire sea.The Nagasaki prefectural government and assembly remain opposed to opening the gates. The 237 billion yen spent on reclamation work has brought lucrative economic benefits to the local economy. In 2002, the Denver group teamed up with the National Renewable Energy Laboratory to build a home that generates a portion of its own electricity from sunlight using photovoltaic modules. Habitat also has collaborated with the Buildings Technology Center at Oak Ridge National Laboratory, a research and development group focused on promoting energy-efficient and environmentally sound building technologies, and the U.S. Department of Energy''s Building America program, which has built more than 14,000 homes with energy-efficient and affordable features. An initiative in Louden County, Tennessee, fostered Habitat''s construction of several Zero Energy Buildings. Structural insulated panels in the floors, walls and ceiling create a tight building envelope and provide insulation, allowing a smaller air conditioner to be installed. A heat-pump water heater saves about 60 percent in water heating energy costs. Solar-electric panels installed by the Tennessee Valley Authority provide power to the house and reduce demand on the utility grid. Some Habitat affiliates have begun to take their homes to even greener heights by incorporating more environmentally responsible building materials. ©2003 www.concrete-saw.net. All rights reserved. |
