The world’s biggest worries are environmental disasters, not economic collapse
For the second year running, business and political leaders think the world’s biggest threat is extreme weather, according to the latest Global Risks Report by the World Economic Forum (WEF) published today.

In recent years, economic risks such as market collapses, fiscal crises, and systemic financial failures, have dropped down the list of concerns, replaced with fears about the environment. WEF, which runs the annual conference in Davos for global elites, found that three of the five most likely global risks for 2018 were environmental—extreme weather, natural disasters, and failure to mitigate climate change.
