Israel, Australia and South Africa are among the most at risk of collapse, thanks to 'deteriorating biodiversity,' finds a new report by a Swiss insurance firm. The report that highlighted India, Spain and Belgium as well, found that one-fifth of the world’s countries are at risk of their 'ecosystems collapsing due to a decline in biodiversity and related beneficial services.' The report claims to be the first of its kind, designed to help insurers assess ecosystem risks when setting premiums for businesses. Among leading economies, China was at the 7th highest risk, followed by US at 9th spot and UK at 16th spot. Brazil and Indonesia enjoyed the highest percentage of intact ecosystems within the G20 list of nations.
