The criminal justice system has enormous difficulty trying to cope. Yet it is a natural phenomenon. We regard ourselves as special, yet we are constantly reminded by this behaviour that we too are subject to the rules of biology. This theorising greatly oversimplifies what happens in the real world. If death wasn't ultimately natural, surely it wouldn't happen so universally.
Some species solve the problem of survival by breeding excessively when times are good.
These species, such as rabbits and some rodents tend to be prey animals. If they are protected from predation, naturally they respond by committing suicide, en masse , by eating themselves to the point of starvation. The rabbits at Quinyambie Station demonstrated this spectacularly some years ago when over twenty million starved in the first month of summer, after a particularly mild and green winter-spring. In the northern hemisphere, lemmings practice an even more spectacular self imposed system of population control from time to time. And as the calicivirus epidemic sputters erratically along, scientists working on an alternative trick to control rabbits hope to actually alter the rabbit's genes to block the reproductive response.
