A WAKE-UP CALL FOR ENVIRONMENTAL HEALTH (p 587)August 20, 2003Issue 23 August 2003 Embargoed 0001 h (London time) 22 August 2003. This week's editorial comments on the new energy bill that will increase US domestic energy supply, concluding that the bill's implications for increased energy consumption rather than conservation is 'a step backwards for health'. The US is responsible for 23% of all greenhouse-gas emissions, mainly a result of burning fossil fuels. The editorial comments: '[George W] Bush's Clear Skies Act 2003 aims to reduce power-plant emissions of sulphur dioxide, nitrogen oxides, and mercury, but ignores the role of carbon dioxide, concentrations of which have dramatically increased over the past century. The new chief of the US Environmental Protection Agency, Mike Leavitt, faces a tough time ahead if the energy bill is enacted, even with the help of the Clear Skies Act.' 'To protect the environment, Leavitt needs to persuade US citizens to use fewer fossil fuels. The Kyoto Protocol, which the USA rejected in 2001, would at least offer a peg around which to enforce reduction of greenhouse gases. Air pollution as a whole also warrants Leavitt's attention, especially now that the link with ill health is clear. Excess deaths and cardiorespiratory illness have been associated with extreme air-pollution episodes where stagnant air conditions led to greatly increased concentrations of soot, sulphur dioxide, and other pollutants from coal fires or factory emissions. Two studies published in this journal last year (Lancet 2002; 360: 1184, 1203, 1210) confirmed that combustion-related particulate air pollution is an important environmental risk factor for cardiopulmonary mortality. One of these studies by Hoek and colleagues showed that living within 100 m of a highway or within 50 m of a major road was associated with a relative risk for cardiopulmonary mortality of 1"¢95 (95 CI 1"¢09-3"¢51).' | |||||||||||||||||||||

Related Fossil News Articles Ancient mother spawns new insight on reptile reproduction A 75-million-year-old fossil of a pregnant turtle and a nest of fossilized eggs that were discovered in the badlands of southeastern Alberta by scientists and staff from the University of Calgary and the Royal Tyrrell Museum of Palaeontology are yielding new ideas on the evolution of egg-laying and reproduction in turtles and tortoises. Future for clean energy lies in 'big bang' of evolution Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria. OU Researchers Isolate Microorganisms That Convert Hydrocarbons to Natural Gas When a group of University of Oklahoma researchers began studying the environmental fate of spilt petroleum, a problem that has plagued the energy industry for decades, they did not expect to eventually isolate a community of microorganisms capable of converting hydrocarbons into natural gas. Study shows continued spread of 'dead zones' A global study led by Professor Robert Diaz of the Virginia Institute of Marine Science, College of William and Mary, shows that the number of "dead zones"-areas of seafloor with too little oxygen for most marine life-has increased by a third between 1995 and 2007. Sky islands: metaphor or misnomer? The term "sky islands" sounds intriguing, but it may be more lyrical than useful when discussing mammal distributions, according to new research from Eric Waltari of the Sackler Institute of Comparative Genomics at the American Museum of Natural History and Robert Guralnick from the University of Colorado at Boulder. A recipe for saving the world's oceans from an extinction crisis Jeremy Jackson, senior scientist emeritus of the Smithsonian Tropical Research Institute and the Scripps Institution of Oceanography, asserts in the Aug. 12 issue of the journal Proceedings of the National Academy of Sciences, that the following steps, if taken immediately, could reverse the demise of the oceans: Establish marine reserves, enforce fishing regulations, implement aquaculture, remove subsidies on fertilizer use, muster human ingenuity to limit fossil fuel consumption, buy time by establishing local conservation measures. Actions of individuals key to saving biodiversity-and ourselves, Stanford biologists say Even if you don't like the outdoors, you're probably pretty fond of air, clean water and food. That makes you a fan of biodiversity, because those essentials for life-human and otherwise-are maintained as a direct result of the Earth's biodiversity, the abundance and variety of species and populations on the planet. Preserving a substantial amount of biodiversity is critical to a healthy future for us, but how best to do that has been a subject of ongoing debate. Improved reaction data heat up the biofuels harvest High food prices, concern over dwindling supplies of fossil fuels and the desire for clean, renewable energy have led many to seek ways to make ethanol out of cellulosic sources such as wood, hay and switchgrass. Fossil and molecular evidence reveals the history of major marine biodiversity hotspots The journal "Science" has published in the issue of the 1st of August the results of a detailed research work about the evolution of marine diversity all through the last 50 million years. Antarctic Fossils Paint a Picture of a Much Warmer Continent National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began a relentless drop millions of years ago.
