There are at least 3.5 thousand invasive (exogenous and threatening local ecology) plant and animal species that harm global biodiversity. Because of them, humanity loses 423 billion dollars every year, says In a new report from the United Nations Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
“Invasive alien species pose a serious threat to biodiversity and can cause irreversible damage to nature, including extinction of both local and global species, as well as threaten human well-being,” the report says.
The IPBES assessment was prepared by 86 scientists who worked on the study for four and a half years.
According to the report, water hyacinth, lantana bush and black rat took the top three places among the most dangerous invasive species. Hyacinths clog waterways and harm fisheries, lantana is rapidly outstripping other native plant species, and black rats are responsible for 40-60% of all reptiles and birds on tropical islands. Researchers also noted the invasive mosquito species Aedes albopictus and Aedes aegypti, which are dangerous to humans due to the spread of West Nile virus and Zika virus.
Most reports of invasive species came from the Americas (34%), followed by Europe and Central Asia (31%), Asia-Pacific (25%) and Africa (7%).
Three quarters of the messages were about terrestrial ecosystems, primarily woodlands and boreal forests. The authors found that since 1970, damage from invasion by alien species has increased 400% every decade. They predict that the damage done by invasive flora and fauna will continue to increase in the coming years.
ancient scientists suggested It regulates the number of invasive wild boars and squirrels with the help of feeding with birth control drugs.
