Invasive species cost $423 billion internationally according to report

The impact invasive species have on biodiversity is costing the world around $423 billion, with costs quadrupling every decade since the 1970s.
That comes from a new report out today on the drivers behind biodiversity loss around the globe.
The top five are invasive alien species, land and sea-use change, direct exploitation of organisms, climate change, and pollution causing massive losses.
Dr Angela McGaughran, a senior lecturer and principal investigator of the Invasomics Lab at the University of Waikato, says only 8 percent of those costs came from biodiversity management.
McGaughran spoke to Corin Dann.
