China`s increasing prosperity and urbanlsm create tons of garbage since the 1980s，causing tons of trouble.The amount of paper,plastic and other garbage has increased more than three times in two decades to about 300 million tons a year．As busy families are shifting from fresh to packaged foods,more garbage is expected．
There are also a huge number of people who go through the garbage to find anything that can be of value and recycled!The recycling is carried out every day when peope come to your house to take away your newspapers and cardboard，plastic and metal items.Every neighborhood has a garbage point.Take a train trip and there are recycling yards all along the tracks in every city. Food waste is collected by farmers to feed animals.
Even though we make an effort to recycle our solid waste，the amount of waste keeps increasing each year．Our biggest problem is where to put the solid waste and how to keep it from polluting our environment.If the solid waste is disposed incorrectly,it can pollute earth`s surface an underground water supplies.Currently,Our municipal waste goes to landfills or garbage dumps.
The waste must be treated to keep rats，flies and other anlmas from building their homes in the landfills.The treatrment also prevents the growth of bacteria that carry diseases．
The government knows such garbage disposal（处理）will always draw complaints．What they need to do is invest more money into bullding and maintaining better evelironment.

fuel supplies, we might be able to use garbage as an energy source.Disposing of the garbage we produce every day is a major problem in cities around the world. In the United States, over 160 million tons of garbage is produced every year. Ten percent is recycled, ten percent is burned, and the rest is put in landfills. But finding land for new landfills is becoming more difficult.
A city that has solved this problem in an unusual way is Machida in Tokyo. They have developed a totally new way of dealing with garbage. The key to the operation is that people should work together. Families must divide their garbage into six groups:
| 1. garbage that can be easily burned, such as kitchen and garden trash 2. garbage that doesn’t burn easily, such as plastic tools and plastic toys 3. products that are poisonous or that cause pollution, such as batteries 4. bottles and glass containers that can be recycled 5. metal containers that can be recycled 6. large items, such as furniture and bicycles |
Nowadays, officials from cities around the world visit Machida to see whether they can use some of these ideas and techniques to solve their own garbage problems.

Electric ears are dirty.In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about "zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---usually coal, oil,but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greens are. covering their eyes---"If I can't see it, it's not happening." Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat---at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars bum more fuel than gas-powered ones. If our electricity came mostly from nukes; or geothermal,or hydro, or solar, or wind,then an electric car truly would be clean. But for political, technical,and economic reasons,we don't use much of those energy sources.
In addition,electric cars' batteries which are poisonous for a long time will eventually end up in a landfill.And finally, When cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.
