Christian Aid's 2007 report "A Rich Seam: Who Benefits from Rising Commodity Prices?" indicates that mining companies that extract raw commodities—such as oil, nickel, or copper—turn the "trade" relationship between the mining industry and particular countries into one giant sucking sound. This is significant, since extractive industries are heavily concentrated in developing countries that are dependent on taxes and wages for a stable economy. The Catholic Bishops' Conference of the Philippines denounced predatory mining acts and open-pit mining in a recent pastoral letter: "Allowing the interests of big mining corporations to prevail over people's right to these sources [of food and livelihood] amounts to violating their right to life."
