The urge to buy the latest gadget and to reform environmental misbehavior may be the twin pillars of 21st century American youth culture, but can the two ever be reconciled? Apple, Dell, Intel, Nokia and others—companies with an array of "green" initiatives and (more) environmentally friendly products—sure hope so. But wind power kite scientist and serial inventor Saul Griffith is skeptical, according to his keynote address at the Greener Gadgets conference in New York City this past Friday.
Griffith, the intellectual force behind wattzon.com ( where you can calculate the energy use of your lifestyle), has another term for the gadget-obsessed, himself included: "planet f&*kers." A detailed analysis of the energy required to produce everything from his daily glass of wine to his iPhone revealed that Griffiths requires some 25,000 watts of energy every day, or nearly twice that of the average American (who is already consuming at least six times as much as the average person in China and more than 20 times as much as the average Indian citizen).

Scientists this week urged further research on tungsten— the metal used to make lightbulb filaments, shotgun shells, electrical wires and even wedding bands—to rule out possible health risks to humans and the environment in the wake of studies showing that it may cause reproductive problems in earthworms and stunted growth in sunflowers.
In an article published this week in Chemical & Engineering News, researchers suggest that not enough is known to determine whether tungsten is safe, and that studies need to be conducted to assess how much is in drinking water and the soil – and whether it poses dangers for humans, animals and plants.
