International Scientific Team Criticizes Adoption of 'Novel Ecosystems' by Policymakers

Novel ecosystems arise when human activities transform biological communities through species invasions and environmental change. They are seemingly ubiquitous, and thus many policymakers and ecologists argue for them to be accepted as the "new normal"—an idea the researchers say is a bad one.
