It"s estimated that one-third of the countries of the world are very rich, and two thirds are very poor. People in the richer countries don"t understand the 1 between them and those in the poorer countries. A very simple example is that a dog or a cat in North America is better than a child in the poorer countries. A fisherman in South America may 2 which is made into pet food while the children in poor countries are not getting enough to eat for their bodies to grow 3 . Although a lot of the world"s natural resources come from these poorer countries, it"s the richer countries that decide what kind of price they 4 pay for these resources. And the prices the richer countries get from their 5 , however, are always rising. So they are getting richer and richer, and the poorer countries are getting poorer.
