What are the advantages to carpooling?

Carpooling is when several people who work together, or who live in the same area, get together and share one car to come to work, instead of each driving a car.

The advantages are:

* fewer cars on the road, not so many traffic jams. * only one car's gas (petrol) is used, so there is a saving on the other cars. Every time a car is driven it contributes by its carbon emissions to building up the greenhouse gas layer, which is causing climate change and global warming.
