Well, we do know that animals survived well in the absence of humans and achieved a balance with their habitat. We know that humans, as predators within that same ecosystem, achieved a different but reasonably sustainable balance with harvests for subsistence.

At the same time, there is quite a bit of evidence that subsistence use coupled with climate change resulted in lots of megafauna extinctions.

In a reasonably wild and undeveloped ecosystem containing the original suite of species hunting might be needed, in a broad-brush sense. But, in reasonably developed areas there will be a lack of major predators and a need for removals by hunting.

There needs to be, in my mind, a lot of education on all sides to achieve good outcomes. Also, here in WA given the manner in which we (we are the government) fund education, homelessness, mental health, crime, infrastructure, etc. I fully believe that elimination of licensed hunters and anglers will doom the resources as there will be no management agency.
