KM-B3 The ongoing amplification of drivers of 
change in nature may substantially increase the 
number of invasive alien species and their impacts 
in the future {B9, B11, B12, B14}. The causal links 
between indirect and direct drivers imply that ongoing 
and future amplification of these drivers will increase the 
frequency and extent of biological invasions and the impacts 
of invasive alien species, which, in some cases, may 
exacerbate the impacts of other drivers. At a global scale,
