With the global warming getting worse,more and more people choose to live a low-carbon life for the purpose of reducing greenhouse gases.

We'd better save much water,electricity and paper. We should use less carbon and oil. It's important to         the lights and computers when we leave a room. We should take our own bags when shopping         using plastic bags from supermarkets. Don't buy unnecessary clothes. Don't buy or use one-off cups or chopsticks or bowls,either. It's         us to walk or ride bikes to school instead of riding in cars. We can also plant more trees to change the air around us.

Let's take action and be low-carbon persons！

Taking away a city's rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can't eat or use. If we kept these things，we would soon have a mountain of rubbish.

In some cities the rubbish is collected and taken outside of city to a dump. Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets,bathtubs and other places.

To keep mice and flies away,some earth is used to cover the newly dumped rubbish. Later,grass may be planted on the rubbish-filled land. Finally,a house or a school may be built there,and then you'd never know that this had once been an old rubbish dump.

In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖质) ，which looks like black earth. It is rich with the kinds of things that feed plants and help make them grow.
