Drive through any suburb in the U.S. today,and it's hard to miss the bins that have become companions to America's trash cans.Recycling has become commonplace,as people recognize the need to care for the environment. Yet most people's recycling consciousness extends only as far as paper,bottles,and cans.People seldom find themselves facing the growing problem of e-waste.

E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced devices,and the majority of them end up in landfills（垃圾填埋地）.Some people who track such waste say that users throw away nearly 2 million tons of TVs,VCRs,computers,cell phones,and other electronics every year.Unless we can find a safe replacement,this e-waste may get into the ground and poison the water with dangerous toxins（毒素）,such as lead, mercury,and arsenic.Burning the waste also dangerously contaminates the air.

However,e-waste often contains reusable silver.gold.and other electrical materials.Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals,which can destroy ecosystems.

A growing number of states have adopted laws to ban dumping e-waste.Still,less than a quarter of this refuse will reach lawful recycling programs.Some companies advertising safe disposal（处置）in fact merely ship the waste to some developing countries,where it still ends up in landfills.These organizations prevent progress by unsafely disposing of waste in an out-of-sight,out-of-mind location.

However,the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner,better place for us all.
