How can we get rid of garbage(垃圾)? Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the time it can save the land to hold garbage. For a long time, people buried garbage or dumped(倾倒)it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas: but they are chemically similar to these fossil(化石)fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil. Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.

Awareness Weeks(认知宣传周)have become a regular part of Britain's cultural landscape over the past few years. They started back in 1957, when one charity(慈善机构), Christian Aid, decided to make all its money-raising efforts on one time of year. It was thought that by doing this they would get more publicity for their cause. They were right, and soon other charities and campaign(活动)groups followed them. These days, most donations(捐款)to charity are not collected on the streets. So instead of just asking for money, charities prefer to spend their time" raising awareness"—spreading knowledge of the work they do or the cause they support. They also compete with businesses and trade groups who use Awareness Weeks as marketing campaigns for their products. There are now 500 Awareness Weeks held every year in the UK. No week goes by without one group or another trying to make the British public aware of something, with most held in May or October. The danger with all these Awareness Weeks is that people start to become cynical(不信任). Take National Smile Week for example, it seems like a great idea: " Let's all make each other's life a little bit happier with a friendly smile. "But really it's just a group of dentists and cosmetics companies trying to sell us toothpaste. It's enough to make you want to start National Forget About It Week. "People feel that many awareness campaigns are just marketing exercises, "says Ms Ormiston, who edits the Awareness Campaign Register, a news letter which encourages people who run Awareness Weeks to become more aware of each other. "But 90 per cent of campaigns are run by traditional charities or not for groups to make money. " "There's still no official group for awareness campaigns, " says Ms Ormiston. "People can do what they like, whatever the size of their budgets(经费)or their public relations machines allows. " This situation has led to calls for laws to stop real charities having their efforts overshadowed by marketing campaigns. This could be done by making the two groups hold their weeks at different times or stopping businesses running imitation(模仿)charity campaigns. But there is another way. Maybe it's time for National Weak Awareness Week, especially for people whose awareness of Awareness Weeks is weak.
