City officials are hoping to use the power of dog droppings. San Franciscans already recycle more than 60% of their dogs’ droppings, but in this dog-friendly town, such wastes make up nearly 4% of residential waste, or 6,500 tons a year.
Within the next few months, Norcal Waste, a company that collects San Francisco’s wastes, will begin a trial program under which it uses biodegradable (生物分解的) bags and dog-waste carts to pick up droppings at a popular dog park.
The droppings will be thrown into a machine called a methane digester (沼气处理机), which is basically a tank in which bacteria feed on droppings for weeks to create methane gas.
The methane could then be piped directly to a gas stove, a steam heater, an air turbine or anything else powered by natural gas. It can also be used to produce electricity.
Someone doubts whether this plan is practical. But Norcal Waste spokesman, Robert Reed points to San Francisco’s creative food composting (混合肥料) program, which began 10 years ago. It is a proof that an unusual idea can work in this forward-thinking city. Norcal Waste collects 300 tons of food left over after meals per day from homes and restaurants and changes it into a rich fertilizer sold to grape farms and organic farms.
Methane digesters are nothing new. The technology was introduced in Europe about 20 years ago, and more than 600 farm-based digesters are in operation there. Nine are in use on California cow farms, and chicken and pig farms elsewhere in the United States also use them.
“The main obstacle is probably getting communities around the country the courage to collect dog droppings, to give value to something we’d rather not talk about,” Brinton, a recycling and composting consultant, said. “San Francisco is probably the king of pet cities. This could be an advantage of it, which is very important.”
Some other experts believe energy production from dog droppings must become more attractive economically before it gets popular. Landfill space is relatively cheap, and natural gas and electricity also remain fairly inexpensive. However, Reed said confidently, “Now, the city authorities asked us to look at dog waste specifically.”

dishes and put them into a box to take with me on my journey. But the customs officer inspected all the plant and animal products at the airport. Unfortunately it was illegal for me to bring into the country the kind of food my mother had given me and so it all had to be thrown away.根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
“Nature does not hurry, yet everything is accomplished.” ---Lao Tzu
If you are in a city where everyone rushes, realize that you don’t have to be like everyone else. You can be different. You can walk instead of driving in rush hour traffic. You can be on your iPhone or Blackberry less, and disconnected sometimes. Your environment doesn’t control your life---you do. I’m not going to tell you how to give you a step-by-step guide to moving slower. 1
1. Do less.
Cut back on your projects, on your task list, on how much you try to do each day. Focus not on quantity but on quality. 2 Save smaller, routine tasks for later in the day, but give yourself time to focus.
2. Have fewer meetings.
3 And they eat into your day, forcing you to squeeze the things you really need to do into small windows, and making you rush.
3. 4
When you do the important things with focus, without rush, there will be things that get pushed back, and that don’t get done. And you need to ask yourself: how necessary are these things? What would happen if I stopped doing them?
4. Practice mindfulness.
Simply learn to live in the present, rather than things so much about future or the past. When you eat, fully appreciate your food. When you are with someone, be with them fully. When you are walking, appreciate your surroundings, no matter where you are.
Try these things out. Life is better when unrushed.
