A new study shows that screening for potentially harmful foreign plant
species before they are imported is more economically beneficial than
fighting them after they take root in new areas. Because the United States
has no screening program for invasive species, the study focuses on
Australia and finds that their prevention efforts pay for themselves with
reduced economic damage in just over ten years and result in up to $1.8
billion in savings over 50 years.
