Global report: Invasive non-native species surge, harming biodiversity & the economy

Thousands of invasive species introduced to new ecosystems around the world are causing more than $423 billion in estimated losses to the global economy every year by harming nature, damaging food systems and threatening human health, a wide-ranging scientific report published on Monday has found.

The costs have at least quadrupled every decade since 1970, according to the report, which was based on 2019 data. Researchers warned that the cost figures were conservative estimates because of the challenges in accounting for all effects.
