01/30/11Antibiotic use in raising food animalsDear EarthTalk: I understand that the use of antibiotics in raising farm animals is threatening to make bacteria overall more resistant to antibiotics, which has serious life and death implications for people. Can you enlighten and advise what is being done about this? —Robert Gelb, Raleigh, NCMost medical doctors would agree that antibiotic drugs—which stave off bacterial infections from staph to salmonella to bacterial pneumonia—are among the most important tools in modern medicine. But public health advocates, environmentalists and even many doctors worry that our society’s overuse and misuse of antibiotics is making bacteria more resistant and thus limiting the effectiveness of these lifesaving drugs.Bacterial resistance to our antibiotics simply means...

01/29/11Reducing global population pressuresDear EarthTalk: Global population numbers continue to rise, as does the poverty, suffering and environmental degradation that goes with it. Has the U.S., under Obama, increased or at least restored its family planning aid to developing countries that was cut when the Bush Administration first took office? —T. Healy, via e-mailThe short answer is yes. President Obama is much more interested in family planning around the world than his predecessor ever was. One of Obama’s first acts upon assuming office in 2009 was the restoration of funding for the United Nations Population Fund (UNFPA). George W. Bush had withheld some $244 million in aid to the UNFPA over the previous seven years. UNFPA works with developing countries around the world to “reduce poverty and to...

01/23/11Energy efficiency tax incentives for 2011Dear EarthTalk: A number of federal energy efficiency related tax incentives expired at the end of 2010. Will any such programs remain in force and if not, are there other ways to save money on green upgrades? —Jen Franklin, Chicago, ILIt is true that some federal tax credits for energy efficiency upgrades expired at the end of 2010, but there is legislative effort afoot to extend some of those credits—and there are plenty of other ways to defray the costs of turning over a new green leaf or two this year and beyond.One of the best known green federal tax incentives, the Residential Energy Efficiency Tax Credit—which kicked in 30 percent of the cost of household efficiency upgrades up to $1,500 on items including water heaters, furnaces, heat pumps, central air...

01/22/11The environment and our healthDear EarthTalk: Aren’t environmental issues primarily about health? Detractors like to trivialize environmentalists as “tree huggers,” but the bottom line is that pollution makes us sick, right? Wouldn’t people care more if they had a better understanding of that? —Tim Douglas, Stowe, VTNo doubt many of the ways we harm our environment come back to haunt us in the form of sickness and death. The realization that the pesticide-laced foods we eat, the smokestack-befouled air we breathe and the petrochemical-based products we use negatively affect our quality of life is a big part of the reason so many people have “gone green” in recent years.Just following the news is enough to green anyone. Scientific American reported in 2009 that a joint... Posted at 04:45 PM | Permalink | Comments |

01/16/1175 percent of world's fisheries are overexploited or significantly depletedDear EarthTalk: What is being done to enable ocean fish populations to rebound after being so over-fished? Are nations coming together on this in any way? —Deborah Kay, Milford, CTThere is no overarching international agreement to limit overfishing globally, but a few governments have been able to implement and enforce restrictions at regional levels that have resulted in rebounding fish stocks. The success of these isolated examples gives environmentalists and marine biologists hope that protecting marine hotspots from overfishing can save the biodiversity of the world’s oceans.The results of an extensive four-year study released in 2006 by leading fisheries expert Boris Worm of Canada’s Dalhousie University and colleagues showed that overfishing would put every...

01/15/11"Greening up" professional sportsDear EarthTalk: What’s being done to “green up” professional sports? I know that the last two Olympic Games both made some effort, but are there others? —Rob Avandic, Chicago, ILThe last two Olympics were indeed greener than any before, but environmental awareness isn’t limited to the realm of international amateur competition. In fact, in just the last few years all of the major professional North American sports leagues have made strides in greening their operations.The Natural Resources Defense Council (NRDC) has helped blaze the trail through its “Greening the Games” initiative. Since 2003, when the National Football League’s (NFL) Philadelphia Eagles turned to NRDC for help saving energy and reducing waste, NRDC has helped dozens of...

01/09/11Atlantic bluefin tuna on the way out?Dear EarthTalk: Are Atlantic bluefin tuna really about to go extinct? What are the contributing factors and what is being done to try to head off this tragedy? —Edward Jeffries, Norwalk, CTAccording to many marine biologists, Atlantic bluefin tuna, one of three closely related bluefin tuna species, are in danger of going extinct within a decade if the governments of the world can’t come together to ban catching and/or selling the lucrative species. The non-profit International Union for the Conservation of Nature (IUCN), which maintains an international “Red List” of threatened species, considers the Atlantic bluefin “Critically Endangered” given that its population numbers have declined by upwards of 80 percent since the 1970s. Even recently... Posted at 11:39 AM | Permalink | Comments |

01/08/11Organic...tobacco?Dear EarthTalk: Is it true that organic tobacco production is booming in the U.S.? And are cigarettes made from organic tobacco any healthier for smokers? —Nanci R., Petaluma, CATo say business is booming would be an exaggeration, but it is true that many American tobacco farmers are beginning to transition to organic growing methods. Given the hard times growers have faced in recent decades—most Americans now revile smoking and farmers in other countries can produce higher volumes for substantially less cost—going organic is one way to keep charging premium prices. While growing organically costs more and yields a slightly less marketable product, farmers can make up the difference and then some since their organic tobacco will command double the price of their...
