When Pope Francis visited the DRC he said that the rich world must realise that people are more precious than minerals in the earth beneath them. Speaking to dignitaries at the presidential palace, he talked of ‘terrible forms of exploitation, unworthy of humanity, where vast mineral wealth fuels war, displacement and hunger. Hands off the DRC. Hands off Africa. Stop choking Africa: it is not a mine to be stripped or a terrain to be plundered.’ Congo has some of the world's richest diamond deposits as well as gold, copper, and other minerals. ‘The poison of greed has smeared its diamonds with blood,’ he said. An estimated 5.7 million people are internally displaced in Congo; 26 million face severe hunger, largely due to armed conflict. Half of the population are Roman Catholics, and the Church plays a crucial role in running schools and health facilities, as well as promoting democracy.
