Vending machines

 I think that the number of vending machines, especially drink’s vending machine, should be decreased. The first reason is that there are too many vending machines in Japan. According to JAPAN VENDIND MACHINE MANUFACTURE ASSOCIATHION, the number of the drink vending machines in 2010 is 2,591,200 and it is increasing than 2009. In addition, Japan is the country where there are most vending machines in the world, because the public peace is safe comparing other countries. Some people say that vending machines are very useful and can buy something to drink anytime. However, there are many cases that there are plural vending machines at a spot and it has a case that there are every 10 meters on the street. The second reason is vending machines are used many electric powers. Some people say the light is useful for crime prevention. However, the electricity consumption of a vending machine is about 500W~1000W.  Moreover, the electricity consumption is increasing by the compressor to heat and ice, a few of light of 40W to advertise it, and the working for 24 hours. For example, if the power consumption per one is assumed to be 1.0KW, the electric power of 5million KW will be consumed. The vending machine will use the power consumption of one nuclear power plant for this. The third reason is that it will decrease a chance to communicate with people if the vending machines increase. Many Japanese seem like it because they may not meet salesperson when they buying something to drink. Then the community may be estranged. That’s way the number of vending machines should be decreased.
