I checked Wikipedia today,it said that the nations of earth are divided into three broad categories:First World,Second World and Third World.
The fist world are the Western European,North Amerian countries and Japan,South Korea,Australia,New Zealand,the second world are mainly Eastern European,Arabian countries and China,the third world is the rest.
They divided this is depended on the economy and the GDP per capital. Yes,I know that per capital GDP in Finland is quite high and people considered to have a really high quality life.But I have some confusion that is the modern things like the latest computers or iPod or digital cameras or mobile phones,you always can see people using them in China.In Finland well not much and even not being seen in the shop. And another thing is that I always saw people especialy old people only buy one banana in the surpermarket and very carefully select that only one.Maybe it is because culture difference,I have never seen or never done things like this before.
Well,maybe that is the differences between the fist world and the second world.Enjoy the clear air and less noise,you have to pay much more.In the second world maybe not that clean and everywhere noise and dirty,but you can enjoy the cheap price and more choices.
