...threat to the ozone layer: nitrous oxide (N2O), otherwise known as laughing gas. A study published in the Aug. 28 Science found that N2O - a by-product of agricultural fertilizer and a number of other industrial processes - is now the biggest ozone-depleting gas in the air, and could present a real threat to the ozone layer in coming decades. And worse, unlike CFCs, N2O - which also adds to global warming - is not regulated by the Montreal Protocol, meaning there is no global effort to try to reduce emissions.

...delve deeper, let's examine why gas prices have deflated so much: natural gas prices and oil prices are no longer bedfellows in our present economy. As crude oil has skyrocketed from about $30 per bbl. in December 2008 to more than $70, natural gas has plummeted from nearly $6 per million BTU to under $3, recently hitting a seven-year low. To put these numbers in perspective, this makes oil more than four times as expensive as natural gas to produce the same amount of energy, according to the U.S. government's Energy Information Administration (EIA).

He organized picnics, sailing excursions, sing-alongs at the piano and touch-football games on the lawn. He presided over all things family. He was the navigator for those young Kennedys who sometimes seemed unsure of their direction as life pulled them between relying on reputation and reality. (See a Kennedy family photo album...
...place that wasn't shrouded in toxic vapors or ravaged by illness. It was the bucolic village of Baigong, in southwestern Guizhou province-a community of blue skies, grape trellises, freshly painted houses and colorful sprays of drying peppers hanging from doorways. Where China's industrial wastelands symbolize its present and past, Baigong may be a tiny herald of the future: its streetlights are solar-powered under a program by Li's One Foundation and the nonprofit Climate Group, which Blair helped launch. "If all Chinese cities had these, we could save a lot of power," said Li. "And also...
