The research noted that two-fifths of ecosystems are at risk of disappearing, while freshwater spineless animals and many pollinators, key organisms for a healthy, functioning planet, are in steep decline.
Likewise, 48% of cactus varieties are endangered, while some 200 tree species (about 20%) are under serious threats.
Out of hundreds of grasses that make up the nation’s great grasslands and wetlands, about one-fifth could be lost forever.
“Preventing plant extinctions is essential to maintaining ecosystem function and services wildlife and people depend on,” according to the study.
As to animals, freshwater species including amphibians, snails, mussels, crayfish and many aquatic insects, have the highest percentage of being at risk.
“Among pollinators, bees are particularly threatened, with 37% of species assessed at risk,” the report continued.
