     Car sharing is another way to drive green which is gaining in popularity, especially in urban areas.

People who may not drive every day but still want a car to run errands (差事) or drive on weekends

benefit most from car sharing. Car sharing is usually run by a service like Zipcar, though there are

nonprofit (非营利的) and informal car sharing services. Members pay a monthly fee and have access to

an entire fleet (队)of cars when they need one. The cars are parked in fixed spots around the city, so

members only need to make a reservation (预订), and then go to the pickup spot.

     Car sharing has major environmental benefits because it reduces the number of cars on the road.

Members don't drive just because they are in a car. They plan trips, and if they don't need a car, they

don't use one. Still, a car is available to them if they need to make a big trip to the grocery store, pick

someone up at the airport or if they want to go to the beach for the day. Members also benefit by having

access to a car without any of the headaches of ownership. They usually don't have to pay for the gas,

insurance or maintenance (保养), and the monthly membership fee is less than a typical car payment. So

if you really want to go green but aren't ready to totally give up a car yet, car sharing may be the way to

go.

     If you still need to get around, but want to go even greener than sharing a car, share a bus!
