Vatican City, November 16 - Pope Benedict XVI has said that globalisation must be based on love, not money and consumerism. "We are passing through a very particular period of history. Technical advances have given us unprecedented possibilities for interaction between people and nations," Benedict said in a message released Friday inviting people to take part in World Youth Day in Rio de Janeiro next year. "But the globalization of these relationships will be positive and help the world to grow in humanity only if it is founded on love rather than on materialism. "Love is the only thing that can fill hearts and bring people together. God is love. When we forget God, we lose hope and become unable to love others".
