The cost of keeping a golf course looking good has traditionally required massive amounts of water, fertilizers, and toxic pesticides that have been doing great damage to the environment. But as sustainable practices become more popular across the globe, many golf facilities go green.
A pancake collapse occurred on Friday at the parking structure that services Washington D.C.’s famed Watergate Hotel. The D.C. Fire Department responded to the failure as one person was injured. The multi-level partial collapse also affected cars parked in the garage. According to officials the area was under construction at the time of the collapse. The Watergate Hotel, which is part of the complex of offices and condominiums, is undergoing $125 million renovation. The 2600 block of Virginia Avenue was closed due to the incident.
With engineers calling it "the most daring project under way in Brazil", the Belo Monte Dam in Amazonia, will have a year operating capacity of 4,500 megawatts, which was rediced to a third of its initial installed capacity of 11,233 MW, as a result of environmental restrictions that led to the reduction of the reservoir's size. The $8.74 billion project is expected to be soon complete so that the dam operated in 2016.
A study performed by the U.S. Geological survey and published in Science reveals that rivers respond quickly to dam removal. In the past forty years, more than 1000 dams have been removed from US rivers due to safety concerns, sediment buildup, and inefficiency. According to Jim O’Connor, a geologist with the U.S.G.S. and lead author of the study, “rivers quickly erode sediment accumulated in former reservoirs and redistribute it downstream, commonly returning the river to conditions similar to those prior to impoundment." Because of this, more and more dams are coming down as a means of river restoration.
China is considering an extension of a railway line that will link the country of Nepal via a tunnel under Mount Everest. This is according to Chinese state media. There is serious skepticism as to whether the project will ever get off the ground, as this is just the latest proposal in a series of ambitious rail schemes Beijing is examining. The project is expected to be completed by 2020 and would forge a crucial trade link between China and India.
A new study, conducted from the Friedrich Schiller University Jena in Germany, indicates that melt waters in airports are responsible for soil contamination. Various de-icing fluids used in airports can affect soil and groundwater conditions during thawing, after ending up in unpaved areas. The research team's results are published in the science magazine "Environmental Science and Pollution Research".
The construction of the first offshore wind farm has just started on US ground in Block Island , a small island 13 miles south of Rhode Island, last Monday. Upon completion, the wind farm will supply all homes and businesses on Block Island with 30-megawatts of electricity. This is the first long awaited step in the offshore wind farm industry on U.S. ground and hopes are expressed that many more projects will follow.
