I would assume that this would be entirely expected. We've entered an age in civilization that has, in effect, united the entire planet. Whether through design or accident, ALL species on the planet are now in contact with each other to some extent.
So we're going from a planet with a huge number of geographically separated regions, with no competition between them, to one region, with all species in competition. Hence all the panic and regulations trying to stem the tide of "invasive species".
What should be expected is that survival of the fittest will take place and a lot of "inferior" species will be wiped out as they can't compete successfully on a global basis. A great extinction even caused by removing all the barriers preventing species competing against each other. That will upset a lot of local ecologies in the short run, but eventually it will even out again - life always finds a balance.
Do we need 130 species of sparrow? If they all have to compete with each other, we'll end up with a lot fewer. I'm not sure we should be concerned when that happens. It's even possible there will be no sparrows at all in the end - that some other species will be better at that niche.
Countless species have gone extinct since life began here. With todays connected world (for better or worse) we should expect a lot more.
