When it comes to the world of computers, green computing is becoming popular. But what is green computing?

   The term “green computing” is one that is being used in many different markets and areas all over the world in today’s global technology. However, many computer users aren’t sure what it means. Green computing is actually quite easy to explain and to do—it is basically learning to use computer resources more efficiently to protect the environment as well as saving energy. The main goal is to reduce the use of energy and materials that harm the environment.

   Green computing started as early as 1992, when the EPA created Energy Star program that improved computing equipment and technologies. Because of this program sleep pattern appeared and many computer users began to adopt this policy to help save energy when they were not using their computers. In October of 2006, Energy Star made the requirements stricter for computers. Because of these new requirements, there are over 20 states that have now set up a special recycling program for old computers to help with green computing.

   Many of today’s IT systems are beginning to rely on both people and hardware to help push their computer systems toward a more green computing system to help both the company and others. This is a hard balance to achieve, as it has to satisfy users. Many companies are learning the best ways that they can go greener when it comes to their computing and also help their business in the process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the world.

   As is known to us, Washington University in St. Louis became the first college in the United States to ban (禁止) selling bottled water in 2009. Since then, more than a dozen small colleges and schools have done the same. The ban isn’t because the schools don’t want students to have easy access to water. Instead, the goal is to encourage students to bring reusable bottles to save money and, more importantly, to save the environment.

   Many people believe that producing and using bottled water not only wastes money but also harms the environment. They say that bottled water is unnecessary because public water supplies in the U.S. are among the best in the world. These people believe that water fountains and reusable bottles with easy access to filling stations are a better choice.

   But the makers of bottled water argue that plastic bottles make up a small portion of the nation’s total waste. They say it’s unfair to single out (单独挑出) their product when so many other items are packaged (包装) in plastic containers, and what’s more, water is a healthy choice compared to some sodas and juices that are also sold at school.

   What do you think: Should sales of bottle water be banned from schools? We want to hear your opinion. Write a 200-word response. Send it to tfkasks4you@timeforkids.com. Your response may be published in a future issue of Time For Kids. Please include your grade level an contact information for your parent or teacher if you want your response to be published.
