One-fifth of the world’s countries are at risk of their ecosystems collapsing because of the destruction of wildlife and their habitats, according to an analysis by the insurance firm Swiss Re.
Natural “services” such as food, clean water and air, and flood protection have already been damaged by human activity.
More than half of global GDP – $42tn (£32tn) – depends on high-functioning biodiversity, according to the report, but the risk of tipping points is growing.
Countries including Australia, Israel and South Africa rank near the top of Swiss Re’s index of risk to biodiversity and ecosystem services, with India, Spain and Belgium also highlighted. Countries with fragile ecosystems and large farming sectors, such as Pakistan and Nigeria, are also flagged up.
Countries including Brazil and Indonesia had large areas of intact ecosystems but had a strong economic dependence on natural resources, which showed the importance of protecting their wild places, Swiss Re said.
“A staggering fifth of countries globally are at risk of their ecosystems collapsing due to a decline in biodiversity and related beneficial services,” said Swiss Re, one of the world’s biggest reinsurers and a linchpin of the global insurance industry.
