Leaving Your Computer On

Standby power, also known as vampire power, the juice used by all those DVD player clocks, coffeepot LEDs and cellphone chargers—accounts for more than 5 percent of all residential electricity use in the U.S., a tab that costs us an estimated $4 billion per year and pumps millions of tons of carbon dioxide into the atmosphere.

Solution? Turn off your computer at night, unplug your iPod when it’s done charging, or put those gadgets on a power strip for one-touch turn-off.

Upgrading Your iPhone

What happens when you toss your old cellphone or computer monitor in the Dumpster? First, you’re contributing toxins like mercury, lead and cadmium into the environment. By some estimates, there are 500 million discarded cellphones in the U.S. alone. Second, you’re wasting precious resources: Electronics contain small amounts of precious metals like gold, silver and coltan, all of which can be reclaimed to reduce often environmentally destructive mining operations. What can you do? Plan your electronics purchases wisely—think about a new phone every three or four years, instead of every six months—and always drop your e-waste off at a recycling center...

Buying Plastic Everything

It’s been said that in 1,000 years, when archaeologists dig down to the 20th and 21st centuries, they’ll deem our time the Plastic Age. The ubiquitous petroleum-based material will be our most prominent artifact, mainly because the stuff doesn’t biodegrade. Besides just making a mess that won’t go away, some plastics are known to leak hormone-disrupting chemicals and other toxins. Until bioplastics—made from vegetable starches and cellulose—become viable, opt for glass containers when you can, and take a reusable bag to the grocery store.
