Soviet-ball makes a good point, there is no purpose to humans at all in the first place, this makes >>33190 your argument invalid. A far better system would be to replace humans entirely with deer and big cats. The deer eat young saplings and expand grassland and the big cats keep the deer population down to prevent total deforestation.

Humans will only be actually useful top predators if and when they can terraform other planets like mars, otherwise they consume more than they are worth. Humans (particularly certain types) over populate, over consume and then starve once the ecosystem they survive on is obliterated.
