The Invasive Alien Species Assessment highlights that 
invasive alien species are a major and growing threat to 
nature, nature's contributions to people, with, in some cases, 
irreversible changes to biodiversity and ecosystems. Invasive 
alien species also dramatically impact the economy, food 
security, water security and human health, sometimes adding 
to marginalization and inequity. The Assessment demonstrates 
that with sufficient resources, political will, and long-term 
commitment, preventing and controlling invasive alien species 
are attainable goals that will yield significant long-term benefits 
for people and nature.
