Talk about nonsense, animals and insects battling for balance not for domination? . . ridiculous. Every creature on this planet battles for one thing, survival and the ability to reproduce, and it will gladly use any means necessary to assure it's dominance and success in that area, and that includes at the expense of the earth and every other organism out there. There is no foresight, no planning, and no conscious to it, just drive and ultimately consequence.
The only balance imposed is by nature, and it's limited resources, any animal that steps beyond it's means gets thrust back by it, but trust me, they try, that's the name of the game. It's been that way since the dawn of time, when the first replicator rose from the primeval sludge.
Humans are just another animal, and have the same drive but we have progressed to the point that we can manipulate the environment too well and have progressed beyond the means that nature has. Our potentially saving grace is that thing that got us in this sticky mess in the first place, our brains and our ability to manipulate the environment to the level we can. If we can do it still remains to be seen.
