New analysis has revealed the stark US$1.28 trillion economic damage caused by the world’s invasive species over the past half century, with a group of global experts warning damage and management costs will soar unless biodiversity agencies can improve prevention and control of biological invasions.
The research, published in leading global scientific journal Nature, shows invasive species have damaged crop yields, critical national infrastructure, human health and diverted billions in taxpayer dollars annually, but too little is being done because the impact isn’t well-recognised by decision-makers and the public.
Biological invasions take place when species of animals, plants and pathogens are deliberately or accidentally introduced in regions not previously occupied by these species.

Recreational hunting – especially hunting of charismatic species for their trophies -raises ethical and moral concerns. Yet recreational hunting is frequently suggested as a way to conserve nature and support local people’s livelihoods.
In a new article published in the journal One Earth, scientists from the University of Helsinki in Finland and Flinders University in Australia have reviewed more than 1,000 studies on recreational hunting – the first such attempt to summarize the scientific literature examining the biodiversity and social effects of recreational hunting globally.
Co-lead author University of Helsinki Associate Professor Enrico Di Minin says while it might seem counterintuitive, there is evidence to suggest some recreational hunting can deliver environmental and social benefits.
