It was your birthday, and you just opened your biggest gift — a smooth silver laptop. You can’t wait to instant-message your friends with the news, but first you have to get rid of your old desktop computer. Do you just throw away the monitor and keyboard in the trash? Not anymore!
Three states, that is, California, Maine, and Maryland, recently passed laws prohibiting people from throwing away electronic waste, or e-waste, includes televisions, computers, and cell phones. Although they don’t make you sick when you use them, they do when they are destroyed, for they contain heavy metals that can be harmful to human bodies. For example, cell phone batteries contain a kind of chemical causing damage to kidneys and deserted computer monitors can damage brains. And flat TV screens may cause injury to the nervous system. Those metals can leak into the ground or give off pollutants when burned.
It is required that e-waste be placed at special sites rather than usual landfills. Several other states are considering similar laws and California is also pushing for a law banning the application of such dangerous substances.
Government officials are not the only people taking aim at e-waste; environmentalists are also urging people to recycle their outdated equipment.
“It is just a waste … to not recycle,” Patrick, an associate professor of occupational and environmental health at university of Iowa, told The Daily Iowan, “Allowing dangerous chemicals to leak into the environment for decades seems irresponsible.”
What Can You Do?
Reduce. Be a responsible shopper, and take care of your electronics so they will last longer.
Re-use. Donate or sell your old high-tech equipment.
Recycle. To find a responsible recycler, contact a local or state environmental group.

Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some avoid doctors because of the high cost of medical care, especially if they lack health insurance. Or they may stay because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctor can also be a deadly game.
Every day, more than six million Americans turn to the Internet for medical answers – most of them aren’t nearly skeptical enough of what they find. A 2002 survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn’t. Look up “headache”, and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2005 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.
The problem is most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative(权威的), so it’d hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.
