Those are interesting thought experiments, but how do we really know it would play out like? Species that aren't predated will keep their own numbers down through fighting afaik.

- riffraff 7y agoI believe we know this for sure due to the Yellowstone park experience with wolves, when they were reintroduced the elk population declined and spread more widely and the flora improved. IANA ethologist anyway.
- duxup 7y agoWe know because of the results of actual experiments and observations. Seals keep kelp forests alive by eating sea urchins. Places where seals were hunted had kelp forests die out and all that left are sea urchins.. all the species that rely on kelp are gone. The sea urchins are still there and dominant ... they're not going anywhere, so they're not managing their population naturally. If you can check out the video.
