Hvad er problemet?

Hvad sker der, hvis man ændrer lidt på ordene i en artikel om biologisk diversitet?

Den 4. Identitet gjorde eksperimentet. Han udskiftede ordet species med ethnic group og ecosystem med society i denne artikel :

“What’s the Problem?
Increasing travel, trade, and tourism associated with globalization and expansion of the human population have facilitated intentional and unintentional movement of ethnic groups beyond natural biogeographical barriers, and many of these alien groups have become invasive. Invasive alien groups  (IAG) are considered to be one of the main direct drivers of biodiversity loss at the global level1, 2. It is clear that IAG can produce substantial environmental and economic damage, and their negative effects are exacerbated by climate change, pollution, habitat loss and human-induced disturbance. Increasing domination by a few invasive species increases global homogenization of biodiversity, reducing local diversity and distinctiveness.

IAS can change the community structure and group composition of native societys directly by out-competing indigenous species for resources. IAG may also have important indirect effects through changes in nutrient cycling, societies function and social relationships between native groups. IAG can also cause cascading effects with other groups when one group affects another via intermediate groups, a shared natural enemy or a shared resource. These chain reactions can be difficult to identify and predict. Furthermore, aggregate effects of multiple invasive groups can have large and complex impacts in a society.

Invasive etnic groups may also alter the evolutionary pathway of native groups by competitive exclusion, niche displacement, hybridization predation, and ultimately extinction. IAG themselves may also evolve due to interactions with native groups and with their new environment.

IAG can directly affect human health. Infectious diseases are often IAG imported by travellers or vectored by exotic etnis groups. IAG also have indirect health effects on society.”
