Researchers say a worldwide breakdown could happen “within a few decades” and have identified five countries most likely to withstand future threats.

The UK and Ireland are among five nations most likely to survive a collapse of global civilisation, researchers have said.

A study has suggested a combination of ecological destruction, limited resources and population growth could trigger a worldwide breakdown “within a few decades”, with climate change making things worse.

A “very likely” collapse would be characterised by the disintegration of supply chains, international agreements and global financial structures, according to researchers at the Global Sustainability Institute at Anglia Ruskin University.

They said problems could spread quickly because of how connected and economically dependant countries are on one another.

Five countries were identified as best placed to maintain civilisation within their own borders, with New Zealand topping the list and followed by Iceland, the United Kingdom, Ireland and Australia.

All of them are islands or island continents which have fewer extremes in temperatures and varied amounts of rainfall due to their proximity to oceans.
