Executives at all levels see an important business role for sustainability. But when it comes to mastering the reputation, execution, and accountability of their sustainability programs, many companies have far to go. A McKinsey & Company article.
Groundwater reserves in the U.S. Southwest are severely low and prospects for their long-term viability are bleak as persistent drought continues to parch the land and prevent recharging, according to an assessment from NASA. As shown in this map, many underground aquifers in the Southwest are extremely dry compared to average conditions over the pastRead More
Andrew Steer, CEO of WRI, and Monique Barbut of the UN Convention to Combat Desertification discuss the urgent need for a global commitment to restoring degraded land and how it may remedy deforestation, desertification and food scarcity.
The expected rise in world population to 9 billion by 2050, and the need for a 70 percent increase in food production from 2006 levels, makes the need for a solution particularly urgent. This challenge will be even more difficult in the face of a changing climate.
The so-called “Desert House” is located in the desert region of Australia, more precisely in Alice Springs. It was designed by the Dunn & Hillam Architects firm and the designers wanted to create something that works in total congruence with the desert wasteland, and doesn’t leave a huge environmental footprint. Cooling is a large consideration when it comes to designing a home in the desert, especially if you want to make the home ...
Along the Delaware River estuary, efforts are underway to restore wetlands lost due to centuries of human activity. With sea levels rising, coastal communities there and and elsewhere in the U.S. and Europe are realizing the value of wetlands as important buffers against flooding and tidal surges.
What do the price of hair-salon services in Beijing and sexual services in London have in common? The answer is that, depending on how you measure them – or indeed whether you measure them at all – the size of the Chinese and British economies will
There’s a class of fuels that don’t use an intervening biomass to make a fuel — so, though they use biology or waste carbon, they’ve bristled at being called “biofuels." Instead, the technologies that depend on unique pathways to converting CO2 and water to fuels a
Trees are saving more than 850 human lives each year and preventing 670,000 cases of acute respiratory symptoms in the U.S., according to the first broad-scale estimate of trees' air pollution removal by U.S. Forest Service researchers. Looking at four common air pollutants — nitrogen dioxide, ozone, sulfur dioxide, and particulate matter with a diameter less than 2.5 microns — researchers valued the human health benefits of the reduced air pollution at nearly $7 billion annually in a study published in the journal Environmental Pollution. The benefits of trees vary with tree cover across the nation, the researchers note. Tree cover in the United States is estimated at 34.2 percent overall, but varies from 2.6 percent in North Dakota to 88.9 percent in New Hampshire. While the pollution-removal capabilities of trees equaled an average air quality improvement of less than 1 percent, the impacts of that improvement are substantial, the study found.
There is an underground Roman-era quarry in The Netherlands that, when you exit, you will find that you have crossed an invisible international border somewhere down there in the darkness, and that you are now stepping out into Belgium; or perhaps it's the other way around, that there is an underground Roman-era quarry in Belgium that, when you exit, you will find that you have crossed an invisible international border somewhere down there in the darkness, and that you are now stepping out into The Netherlands.
However, this is not just a disused quarry—not just an archaeological site on the fringes of the Roman empire that was once mined for blocks of limestone. Its afterlife is by far the most interesting part of the story.
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny).
Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers,tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
