But many scientists say that people are doing many things which makes the earth warmer. First, greenhouse effect is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate change is another important reason. Sometimes it becomes too hot and sometimes too cold.

Almost everywhere eating together means that people are very friendly to each other. But in parts of Polynesia it is bad manners to be seen eating beside each other. So they politely turn their backs to each other when they are taking food. Some East Africans spit four times as a kind of blessing .They do it to show that they want a sick person to get well,or to bless a new-born baby. In most other places,spitting means something completely different. It usually shows an unhealthy habit. In many countries,it may mean that you hate someone. When we go to visit someone we say " Hello!" Or " How are you ? " or things like that.
