...least 14 new cubs have been spotted in the past 18 months, and there may be more to come: forest guards report that two more tigresses may be pregnant. The sudden abundance of tiger tots has delighted conservationists. Some are already looking into the future and predicting a problem of plenty. "These babies are great news," says Ravi Singh, head of the World Wildlife Fund in India. "The question is, 'What happens next?' When they grow up, when they're bristling tigers that end up in your yard, will we still love them...
...many tigers? That's not a problem India is likely to face any time soon. Ranthambore is a rare success story in the country's attempts to save its national symbol from extinction. In February, a government-backed report found there were about 1,400 tigers left in the wild--a drop of more than 60% in five years, driven by poaching and human encroachment into tiger habitats. Conservationists are studying Ranthambore's success closely, hoping to replicate it elsewhere. The lessons learned here are vital not because they illuminate some secret key to saving the big cat but because...
...Oglala Sioux tribe, living on the Pine Ridge reservation in South Dakota. There are a lot of things that are going to make life a challenge for you, but one of the most perilous will be your weight. Chances are very good that your parents already have a weight problem; obesity is rampant in the 30,000-member community, and half the residents over the age of 40 have Type 2 diabetes. Their genes--and yours, of course--are part of the problem: researchers theorize that Native Americans have a higher than average tendency to gain and store weight...
...secret that the U.S. has a crippling weight problem and that our children are hardly exempt. Rising obesity threatens to condemn a significant share of the next generation to a lifetime of weight-related disease, overburdening the already struggling U.S. health-care system. Though a recent study by Centers for Disease Control and Prevention (CDC) researchers found that childhood-obesity levels may finally have leveled off, more than 30% of American schoolchildren are still overweight, with little indication that rates will drop anytime soon. The CDC defines as overweight those children with a body mass index (BMI)--a rough factoring...
...that provides a new way to look at--and attack--obesity. We tend not to talk about a problem like body weight in the language of infectious disease, but scientists do, knowing that like any other epidemic, the U.S.'s obesity scourge hits some communities harder than others. The skyrocketing increase in childhood obesity--the percentage of 6-to-11-year-olds classified as obese has nearly tripled since 1980--may argue strongly that the American environment has changed in a way that makes gaining weight much less avoidable. But the uneven distribution of the problem argues that...
