10% Of 37,000 ‘Alien Species’ Catalogued Worldwide Aggressively Harmful, Warns UN Report

London: A major scientific assessment under the United Nations (UN) stated on Monday that more than 37,000 alien species across the world have been catalogued, of which 10 per cent are classified as aggressively harmful, or ‘invasive’.

The species range from rats, cats and mosquitoes to a rogue’s gallery of plants, reported AFP.

Humanity’s growing population, economic growth, land-use change and climate change, “will increase the frequency and extent of biological invasions and the impacts of invasive alien species”,

IPBES, an intergovernmental science advisory panel for the UN Convention on Biodiversity, warned in a report that humanity’s growing population, economic growth, land-use change and climate change, will “increase the frequency and extent of biological invasions and the impacts of invasive alien species.”
