...keeps one eye open while washing your face (the better to catch ghostly reflections in the mirror, of course), here's another horrifying bathroom scenario you might not want to hear: every time you turn on your shower, you are sprayed with a heavy mist of millions of bacteria, which get inhaled deep into your lungs...
...such microbe called Mycobacterium avium is similar to the bug that causes tuberculosis (TB) and causes lung infection. It is also found commonly in showers in New York and Colorado, according to a new study led by University of Colorado microbiologist Norman Pace, who studies bacteria found in homes, schools, public buildings and other human environments. (See the top 10 scientific discoveries...
...industrial way of life. The millions of tons of soil fertilizer used in U.S. agriculture alone add N2O into the atmosphere, as do livestock manure, sewage treatment and automobiles. And it's not just our doing: two-thirds of global N2O emissions come from the planet itself, as bacteria in soil and the oceans break down nitrogen. Though N2O is regulated by the Kyoto Protocol of 1997 as a greenhouse gas - and one that is nearly 300 times more potent for global warming than CO2 - that treaty doesn't cover all nations, and will expire in 2012. "The question...
...prices. But it does so at a high cost to the environment, animals and humans. Those hidden prices are the creeping erosion of our fertile farmland, cages for egg-laying chickens so packed that the birds can't even raise their wings and the scary rise of antibiotic-resistant bacteria among farm animals. Add to the price tag the acceleration of global warming - our energy-intensive food system uses 19% of U.S. fossil fuels, more than any other sector of the economy...
...stay alive and grow in such conditions, farm animals need pharmaceutical help, which can have further damaging consequences for humans. Overuse of antibiotics on farm animals leads, inevitably, to antibiotic-resistant bacteria, and the same bugs that infect animals can infect us too. The UCS estimates that about 70% of antimicrobial drugs used in America are given not to people but to animals, which means we're breeding more of those deadly organisms every day. The Institute of Medicine estimated in 1998 that antibiotic resistance cost the public-health system $4 billion to $5 billion a year - a figure that...
