One fifth of ecosystems is in danger of collapse – here’s what that might look like
One-in-five countries are at risk of their ecosystems collapsing, according to recent research.When ecosystems collapse, they rapidly lose their structure and function, with dramatic changes to their size or extent.Collapse on this scale would threaten more than half of global GDP (US$42 trillion, or £32 trillion).Professor of Physical Geography, John Dearing explains what collapse means - and what we can do about it.
