The World Social Forum met for the first time at the end of last month in Porto Alegre, Brazil. The World Social Forum is a new international conference that will meet every year. Its goal is to create and exchange social and economic projects. The projects will support human rights, social justice and development that does not waste natural resources.
    Most of the representatives at the recent World Social Forum oppose globalization. They do not agree with the economic theory of a worldwide economy. Some people attending the forum wanted to end the movement toward a global economy. Others wanted to reform it.
    Activists at the World Social Forum say globalization policies have caused a greater inequality between the poorest and the richest people in the world. The Forum met to find ways to support economic policies based on the needs of poor people and the environment.
    United Nations studies show that the poorest 20% of the world’s people have lost half of their share of the world’s income since 1960. Their share dropped from 2.4% to 1.1%. During the same years, income increased for the richest twenty percent of the population. The rich people increased their share of world income from 69% to 86%.
