You have to consider the period of time over which those species became extinct. Per E.O. Wilson, we're losing species at a rate that is ~1,000 times faster than anything in the past. If it continues, the loss in biodiversity will lead to the breakdown of many ecosystems that we depend on for survival.

The species extinction rate is very high at the moment, but large impact events probably produce a higher rate and larger ecosystem disruption. The Chicxulub impact extinction event was a much worse than our current situation.

Damning with faint praise if the best we can say about our actions is “hey, at least we’re not as bad as this globally cataclysmic asteroid impact”.
