Hindu View on Overpopulation

If the Hindus are correct and the whole idea of reincarnation is true than wouldn't overpopulation and massive herds of cows be a sign that souls are being promoted at a higher rate? I mean lower species are disappearing at an accelerated pace while higher species, like us, are increasing quickly. Or if you look at the spread of much lower species like jellyfish and cockroaches than perhaps we can see an ever increasing divide between the karma rich and poor. This great divide needs immediate legislative intervention to close the karma gap.
