Invasive species
Some invasive species
Zebra mussels
Clog pipes
Water Hyacinth
Most widespread invasive plant on Earth
Render lakes dry, impede boat traffic and fishing
Most widespread: black rat
Found in cities and remote islands
Tropical fire ants
Destructive goats in the Galapagos
Rodents in the South Atlantic island of Georgia were exterminated by conservationists
Emerald ash borer are tree-killing insects found in North America
Solutions
Border monitoring
Import controil
International agreement in Montreal
Reduce the spread of harmful species by half by 2030
Prevention
Eradication is possible especially on islands
Emerging technologies
Special strain of bacteria in Hawaii to suppress mosquitoes
Tinkering with genes
Mosquitoes targeted
Consequences
Destroying crops
Diseminating pathogens
Wreaking havpk
Depleting people from food
Driving native plants/animals to extinction
Biodiversity crisis
The report
Body : 140 countries
Scientific assessments
Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem services (IPBES)
Protection + prevention
'Threat is underappreciated, underestimated, and often unacknowledged.'
200 new species a year
Unprecedented rate
Situation on some remote islands
Prone to invasion
Harbor plants and animals found nowhere else
Black rat decimated ground-nesting seabirds + other animals
Profound impact + impact on reef fish with the flow of nutrients being altered into the ocean
Drive some species to extinction
Ex: on Guam with the brown tree snake
Catastrophic fires in Maui
Invasive grasses fueled wildfires
Aquatic ecosystems also endangered
Caribbean
Venomous Lion fish
Driving down nb of native fish
Four key drivers of extinction
Habitat destruction
Pollution
Climate change
Direct exploitation of species
Climate change as a major catalyst
Species will be able to thrive in other regions of the world
Antartica is not spared
Grasslands?
Species will be able to settle into higher latitudes
Threat to
Human civilization

$423 billion a year
