Why are we a nation of tree-huggers? 3 February 2011Last updated at 15:44 By Jon Kelly BBC News Magazine Plans to transfer ownership of many public forests in England have provoked a huge row. But why are we so protective of our woodlands? It's about the rustling of the leaves and the crunch of twigs underfoot. It's the sensation of the rough bark on your hands and the light dappling into a clearing. The Role of Decoherence in Quantum Mechanics First published Mon Nov 3, 2003; substantive revision Mon Apr 16, 2012 Interference phenomena are a well-known and crucial aspect of quantum mechanics, famously exemplified by the two-slit experiment. There are situations, however, in which interference effects are artificially or spontaneously suppressed. The theory of decoherence is precisely the study of (spontaneous) interactions between a system and its environment that lead to such suppression of interference.
New global maps detail human-caused ocean acidification A team of scientists has published the most comprehensive picture yet of how acidity levels vary across the world's oceans, providing a benchmark for years to come as enormous amounts of human-caused carbon emissions continue to wind up at sea. "We have established a global standard for future changes to be measured," said Taro Takahashi, a geochemist at Columbia's Lamont-Doherty Earth Observatory who published the maps with his colleagues in the August issue of the journal Marine Chemistry. The maps provide a monthly look at how ocean acidity rises and falls by season and geographic location, along with saturation levels of calcium carbonate minerals used by shell-building organisms. The maps use 2005 as a reference year and draw on four decades of measurements by Lamont-Doherty scientists and others. The oceans have taken up a quarter of the carbon dioxide humans have put in the atmosphere over the last two hundred years.
Conservation in Belize A bluehead wrasse in the Belize Barrier Reef, part of the world's second-largest coral reef system. Since declaring independence in 1981, Belize has enacted many environmental protection laws aimed at the preservation of the country's natural and cultural heritage, as well as its wealth of natural resources. These acts have established a number of different types of protected areas, with each category having its own set of regulations dictating public access, resource extraction, land use and ownership. Roughly 26% (2.6 million acres, or 1.22 million hectares) of Belizean land and sea is preserved within a total of 95 reserves, which vary in their purpose and level of protection. This network of protected areas exists under a variety of management structures: 1,900,469 acres (769,093 ha) of terrestrial reserves,392,970 acres (159,030 ha) of marine reserves,317,615 acres (128,534 ha) protected through officially recognised private conservation initiatives.

60 Years of American Economic History, Told in 1 Graph - Jordan Weissmann In the 60 years after World War II, the United States built the world's greatest middle class economy, then unbuilt it. And if you want a single snapshot that captures the broad sweep of that transformation, you could do much worse than this graph from a new Pew report, which tracks how average family incomes have changed at each rung of the economic ladder from 1950 through 2010. Here's the arc it captures: In the immediate postwar period, America's rapid growth favored the middle and lower classes. The poorest fifth of all households, in fact, fared best. Then, in the 1970s, amid two oil crises and awful inflation, things ground to a halt.
Data-driven Insights on the California Drought (12/8/2014 8:33:13 AM) A newly released interactive California Drought visualization website aims to provide the public with atlas-like, state-wide coverage of the drought and a timeline of its impacts on water resources. The U.S. Geological Survey developed the interactive website as part of the federal government's Open Water Data Initiative. The drought visualization page features high-tech graphics that illustrate the effect of drought on regional reservoir storage from 2011-2014. Birds of Belize and Central America With over 587 different, colorful species of birds in the country, Belize is a must for the professional or amateur bird-watcher and those into eco tourism. In the Orange Walk District alone, over 400 species of birds have been recorded. Of these, approximately 20 percent are migrants from North America. Almost every year new species are reported. Eight new records were confirmed in 2007, including the Crested Caracara, Canada Goose, and Spot-breasted Oriole.
Dutch Study Says Wi-Fi Makes Trees Sick A recent study by Dutch scientists found that Wi-Fi radiation could be responsible for sickness in urban-populated trees. Image: baltimoresun What would life be like without Wi-Fi, bringer of high speed internet access? Probably pretty inconvenient considering that millions of computer users around the world use it at home, at work and other public places to get online. Having access to wireless networks makes our lives easier, but according to a Dutch study from Wageningen University, this access may be compromising the health of trees.

Design Science Primer Comprehensive, anticipatory design science is “the effective application of the principles of science to the conscious design of our total environment in order to help make the Earth’s finite resources meet the needs of all of humanity without disrupting the ecological processes of the planet.” The term “design science” was coined by Buckminster Fuller to characterize his unique approach to solving complex problems. A number of important features characterize Fuller’s design science approach. As a process, it must be comprehensive - driven by holistic systems thinking; it must be anticipatory - needs driven and future oriented; it must be aligned with nature - reflecting nature’s underlying processes and principles; and, it must be science based - subject to rigorous concepts, testing and empirical verification. A world that works for 100% of humanity
List of birds of Belize This is a list of the bird species recorded in Belize which consists of the mainland of Belize and around 450 smaller cays and islands lying in the Caribbean Sea. The avifauna of Belize includes a total of 590 species, of which 2 are globally endangered and 4 have been introduced by humans. The following tags have been used to highlight certain relevant categories. The commonly occurring, native, species do not fall into any of these categories.
