Global Biodiversity Panel Warns Humans’ Introduction of Invasive Species Threatens Nature, Food Security

Abstract

Publication: Common Dreams

A new report by the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) highlights the increasing threat of invasive alien species, introduced through human activities like colonization and trade. The study, based on five years of research across 49 countries, documents over 3,500 harmful species affecting ecosystems, food security, and human health. The global economic cost of invasive species has quadrupled every decade since 1970, surpassing $423 billion in 2019.

Experts warn that climate change and intensified global trade will further accelerate the spread of invasive species, exacerbating their negative impacts. The report emphasizes the disproportionate harm to Indigenous communities and local biodiversity. However, it also outlines strategies for mitigating damage, including border biosecurity measures, import controls, and public awareness campaigns. Researchers stress that proactive human intervention is key to controlling the spread and minimizing long-term ecological and economic consequences. Decision-makers are urged to act on the report’s recommendations.
