Ryan was speaking on Friday at a charity event focusing on the challenges of poverty and injustice in the developing world.
“We are pushing nature to its limits. We are pushing populations to its limits. We are pushing communities to its limits, we are stressing the environment,” said Ryan.
“We are creating the conditions in which epidemics flourish,” he warned.
“We are doing it in the name of globalisation and some sense of chasing the great thing that people are calling economic growth,” he noted, adding that it was leading to unsustainable practices.
“We are writing cheques that we cannot cash as a civilisation for the future and they are going to bounce. And my fear is that our children are going to pay that price.”
