I am thinking mainly in terms of the evolutionary impact of reduced populations sizes and genetic diversity, adaption to anthropogenic habitats and radiation potential of interchange between biogeographic regions (i.e. alien species) and then indirectly how the community structure in ecosystems [old (anthropogenic) and new (anthropogenic)] may change?
"radiation potential of interchange between biogeographic regions (i.e. alien species)". Probably hybridization and introgression among previously isolated (by habitat, by geography) populations and species are important outcomes of globalization. Outcome is an increase in genetic diversity.
Sadly, it seems that in future the Anthropocene will, on the whole, just be a slow mass extinction, as it has been in the past. But if enough people care about our non-human cousins, and the biota of the planet as a whole, perhaps we could reverse the trend. I live in hope!
