Professor Helen Roy: Prevention is really the best way to deal with invasive species. Patrick Greenfield: We need to ensure that we effectively communicate the issues around biodiversity loss and the biodiversity crisis. The Guardian's forward slash charity appeal 2022 will raise funds for those who have been hit hardest by cost of living crisis.
Invasive non-native species are on the rise around the world and, despite efforts to tackle the issue, their numbers are higher than ever. They have become one of the key driving forces behind biodiversity loss, posing an even greater threat to biodiversity than the climate crisis. Monitoring, tracking and managing invasive species is one of the issues up for discussion at the UN’s biodiversity Cop15, which is now in full swing in Montreal, Canada. Ian Sample gets an update on how Cop15 is progressing from biodiversity and environment reporter Patrick Greenfield, and hears from Prof Helen Roy from the UK Centre for Ecology & Hydrology about why invasive species pose such a serious risk to native wildlife.
