After a long day at school, I walked home with my heavy schoolbag . By the time I got home, I was sweaty,  16 and hungry.

Everyday rubbish could provide a valuable source of energy thanks to a clever new invention. Smelly methane（沼气）gas expelled from landfill sites containing tones of rotting household waste could be used to produce a valuable energy resource. In Europe alone land fill tips produce 94 billion cubic meters of methane per year but currently only one percent of what could be a valuable source of energy is used, the rest is burnt off to prevent an explosive build up of gas.
Methane gas forms when organic matter breaks down and is drawn off from large rubbish tips by pipes sunk into the middle of the waste. Until now this process wasn’t possible on small sites because the pipe allowed oxygen to seep in and that stop the breakdown process.
Viktor Popov of the Wessex Institute of Technology has now developed a system to modify existing landfill sites by making them airtight while the methane is extracted from sunken wells. The site is covered by a special three-layered skin whose two outer layers are made of clay with a pressurized（加压的）layer of carbon dioxide gas in the middle. As the methane is sucked out through a central well it is replaced by carbon dioxide from the middle layer rather than oxygen, allowing the breakdown process to continue.
Unfortunately there are no plans to use the power of methane even though Popov claims his invention could provide a valuable source of energy over the next 20 years.

We can all contribute to a greener world．Just follow these ten golden rules:
●Stop getting junk mail．Billions of junk mail can be sent every year．Half of it is never opened．Get-your name off mailing lists．If 100,000 people stopped getting junk mail today, it would save 150,000 trees a year．
●Stop reading newspapers．All over the world, millions of newspapers are thrown away every day, 44 million newspapers in the USA alone —that's half a million trees a week．Either recycle your newspapers or read the hews online．
●Buy clothes made from organic materials．Conventional cotton farming seriously pollutes the environment, most of which uses chemical pesticides （农药） and fertilizers． Organic is better!
●Switch to solar energy．In one day, the sun will provide enough energy to power the planet．Why aren't we using it?
●If you have to drive, share the ride．Most cars in the USA have only one occupant．Also, 25 percent of car rides are less than 1．5 kilometres．Get out and walk!
●Unplug your PC, TV and VCR．Simply turning them off isn't enough．Sets left on standby are still using 25 percent of their power．
●Hold on to your balloons．Helium-filled balloons which fly away usually end up in a lake or river, where they can choke aquatic (水生的) creatures．Save your balloons and use them again．Or better still, don't use them at all．
●Feed the birds．Wild birds need food, especially in v/inter when other sources can be scarce．The greater the range of foodstuffs you put out for them, the more types of birds you will attract．
●Plant a garden at your school．Learn the connection between the land and the table．Plant vegetables to eat, flowers to admire and trees to improve the air．
