Those societies currently experiencing the biggest problems with invasive alien species are those wealthy Western human societies that typify Dasmann’s (1988) concept of ‘biosphere people' societies whose wealth, access to technology and cultural background have led them to rely on resources derived from every corner of the globe. Societies at the other end of the continuum,
Dasmann’s ‘ecosystem people’, have historically relied less on commodities and organisms drawn from distance biomes.There has thus been less propagule pressure, and these societies
currently experience less severe problems with invasive alien taxa
