The fact of the matter is that humans have become the dominant species and yes we have changed the face of the planet. We have devastated entire species of other animals
in the process. I would like to think that as we learn from that, we actually have a responsibility to manage some of these things.
There are two big differences between saltwater crocs and deer.
Firstly, crocs are at the top of the food
chain, which is a lot like a pyramid, so their numbers are naturally smaller. If their numbers become to large, their prey numbers go down and they start to die off. It's kinda nicely balanced. Deer however, if their numbers become too large, they overgraze plants, which play a much more important role for the whole ecosystem in general. Overgrazing can significantly damage the environment
Also maturity times are vastly different. Deer take a year to reach maturity, while salties take 15 or so years. Kill 20% of all deer every year and their numbers will be fine. Without predators, its a good way of avoiding overpopulation. Do the same with crocs and they will be critically endangered in a decade.
