For computer users, there is no bigger excitement than tossing out your old PC and upgrading to a newer, faster and cleaner machine. With hardware designers like Intel, pushing newer, faster products every year, and new software requiring even more powerful machines, companies and consumers have little choice but to go along.
But this rapid turnover is having a serious effect on the planet. Producing a personal computer consumes large quantities of natural resources. A recent study by the United Nations estimates the energy required to produce a single new computer is equivalent to nearly two barrels of oil. And that doesn't include the 22 kg of chemicals or the 1,500 kg of water used in the manufacturing process.
In fact, pound for poun

process for making a car is about 500% more efficient than that for making a computer. That doesn't matter so much 20 years ago when personal computers were few and far between, but times have changed. These days, computers are found nearly everywhere and sales continue to grow. The number of PCs in use topped one billion in 2002.
Waste in production is only half the problem. Old computers, especially the monitors, are full of dangerous substances, which need to be carefully recycled. The problem is sure to expand over the coming years as users replace their boxy CRT monitors with LCD flat displays.
Europe now requires that 70% of parts from old computers be recycled, but the study’s authors say that’s also part of the problem. The solution, they insist, is for governments and companies to encourage people to use their computers longer, and upgrade rather than replace. But considering that much of the world’s recent economic growth has come from spending on computers and information technology, that advice may sound like wishful thinking.

It was getting dark and snow was coming down. Joe was driving home. He’d been unemployed since the factory closed. Most of his friends had left, but he stayed on. After all, he was born here.
Suddenly he saw a lady standing on the side of the road and pulled up. She was worried. No one had stopped to help her. Was he going to hurt her? He looked poor and hungry. Joe knew how she felt and said, “My name is Joe and I’m here to help you.” All she had was a flat tire, but for an old lady, that was bad enough. Joe changed the tire, but he got dirty and his hands were hurt. She wanted to pay Joe and said any amount would have been all right. Joe never thought twice about the money and there were plenty who had given him a hand in the past. He had lived his whole life that way. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance that they needed.
Later the lady went in a dingy-looking restaurant to grab a bite to eat. The cash register was like the telephone of an out-of-work actor----it didn’t ring much. The waitress, who was nearly eight months pregnant, brought a clean towel to her with a sweet smile. The old lady remembered Joe. After the waitress brought the change from a 100-dollar bill, she found the lady gone and something written on a piece of paper, “Someone once helped me out----the way I’m helping you. If you really want to pay me back, don’t let the chain of love end with you.”
That night the waitress gave her sleeping husband a soft kiss and whispered, “Everything’s going to be all right. I love you, Joe.”
