Novak is among a small group of "de-extinction" engineers, a relatively fringe group of scientists that hope to use genetic engineering to protect or revive iconic animal species ravaged by human activity.
To some, de-extinction is an ecological-sized guilt trip, a species-wide Pet Cemetery horror story ripe for disaster. Yes, biodiversity is important; but who is to say that an extinct species can adapt and survive in an ecological system that's moved on since its passing? Or perhaps more importantly, what if newly-revived animals—a true "invasive species" for Earth—cause more damage than good to our fragile ecosystem?
"Why go through the trouble" is something his team gets asked, said Novak. For passenger pigeons, the answer is simple: recently, almost a
millennium[century] after their man-driven extinction, we finally understand the critical role they played in shaping the eastern North American ecosphere.
The passenger pigeon isn't extinct -- it's merely resting.

So what top of the food chain predator went extinct because the passenger pigeons went away? It wasn't humans.

Not necessarily extinct (although I am sure there were some), but certainly raptors, small mammals. reptiles and amphibians, insectivores and others all depended on the ecosystem engineered by the pigeons. Dispersal of seeds, the guano deposited and direct predation and scavenging all changed enormously in a short period of time.
