Drylands cover 41 percent of the Earth’s land surface. Of that area, desertification has rendered 20 percent unfit for human use, and an additional 70 percent remains vulnerable. According to the United Nations, desertification is degrading soil quality in 110 countries, directly impacting 250 million people and threatening a billion more, all without creating a single new desert.
Forest protection advocates are cheering a ruling last week by Federal Judge Elizabeth Laporte to throw out the Bush administration’s roadless area development rule of 2005.
Against the recommendations of a long list of science and health organizations—not to mention two of its own scientific advisory committees—the U.S. Environmental Protection Agency (EPA) announced last week it would leave in place its 1997 standards for annual exposure to particulate pollution (soot generated from coal-fired power plants, industrial facilities and vehicles), while only moderately strengthening its daily exposure soot standard.

This year it was on steroids, occupying the vast concrete plaza outside Boston City Hall September 22 and 23.
Randy Miles likes to teach soil science from pits dug deep into the earth. The University of Missouri soil science professor enjoys taking his students into the field, prying clods from the pit face and showing the distribution and properties of soils across Midwestern landscapes.
A solar hot water heater could save you money on utility bills and also help mitigate the effects of runaway climate change.
Can toxic waste be turned from a disposal problem into a useful and benign fertilizer? That’s the question some scientists and activists are asking about a product that is routinely used by farmers and home gardeners to feed their soils.
If soils do indeed achieve the higher profile they so desperately need, John L. Havlin will be one of the people to thank. The professor at North Carolina State University is past president of the Soil Science Society of America, and a dedicated campaigner whose work is helping to establish the House of Representatives Soils Caucus and a $4 million Smithsonian educational exhibit on the subject, opening in 2008.
Now that autumn is here the leaves are going to pile up in my yard again. Is it really that bad to burn them?
