If you haven’t thought about how much water you’re drinking lately, you’re probably drinking enough, says Dr. Heinz Valtin, a retired professor and kidney specialist at the Dartmouth Medical School, who recently spent 10 months studying the question. Valtin cautions that drinking too much water may increase exposure to water-borne pollutants, and may increase the risk of water intoxification, also called hyponatremia, a sometimes fatal condition that is the result of replacing lost fluids much faster than sodium.

The State’s Rapid Population Growth is Largely Due to Immigration Nowhere in America is immigration more of a battleground than in California, where a trickle of new residents has become a flood. According to the Center for Immigration Studies, in 1960 the state held 8.8 percent of the nation’s population and 13.9 percent of its […]

Louden County, Virginia, the third-fastest-growing county in the country, could easily become the outward-most link in the Washington, D.C. "edge city" corridor. The commute to the nation’s capitol is only an hour and a half, land is cheap.

The world is sharply divided in terms of access to safe hydration. Those who can afford it are guzzling ever-increasing numbers of designer water bottles, while half the world’s population lacks basic sanitation facilities, according to the United Nations (UN). Diseases caused by unsanitary water kill five to 12 million people a year, most of them women and children. A child dies every eight seconds from a preventable water-borne disease.

The Good, the Bad, the Ugly Even though it’s made of only three little molecules of oxygen, ozone can be a pretty big topic. Newspaper headlines are confusing: One day ozone is good, the next day it’s bad. In fact, both scenarios are true. Two types of ozone exist, stratospheric and tropospheric, and they differ […]

A comprehensive endangered species report is impossible in this limited space, so E chose to focus on 10 of the most seriously endangered. This isn’t a scientific selection, but a subjective appraisal of species that, we believe, can still be saved by a concerted global effort. This list has some overlap with the 25 species […]

The Paper Industry Moves South Flying over the 500,000-acre Great Smoky Mountains National Park last year in a Cessna 180 operated by the nonprofit group Southwings, writer Chris Camuto could clearly see evidence of the park’s enormous and breathtaking biodiversity, home to an estimated 100,000 species. The scenery changed when the plane crossed the Tennessee […]

With tap water quality increasingly under fire in the court of public opinion, the market for home water filter systems has surged. Co-op America says consumers who are still concerned about their tap water, or who don’t like its taste, should consider filters over bottled water, since they are less ecologically harmful (and considerably cheaper per serving). Filters are reusable and result in less waste and transportation than bottled water.

According to the United States Census Bureau, the population gains a new American every 11 seconds, and 2.5 million a year. Of that total, more than a million were born somewhere else. Between 1901 and 1990, 37 million immigrants arrived on American shores, an epic movement of people looking for a better life. Why do […]

The Fight to Save the ESA Wildlife protection is headed for a showdown, but it may not come in the current Congress. The main players are Senator Dirk Kempthorne (R-ID) and Representative George Miller (D-CA); both have sponsored bills which, if passed, would dramatically change the face of the Endangered Species Act (ESA). Senate bill […]
