In recent months, the pope has argued for a radical new financial and economic system to avoid human inequality and ecological devastation. In October he told a meeting of Latin American and Asian landless peasants and other social movements: “An economic system centred on the god of money needs to plunder nature to sustain the frenetic rhythm of consumption that is inherent to it.

“The system continues unchanged, since what dominates are the dynamics of an economy and a finance that are lacking in ethics. It is no longer man who commands, but money. Cash commands.

“The monopolising of lands, deforestation, the appropriation of water, inadequate agro-toxics are some of the evils that tear man from the land of his birth. Climate change, the loss of biodiversity and deforestation are already showing their devastating effects in the great cataclysms we witness,” he said.
