Why nature likes balance?

Question

I mean when something is getting too much, the nature makes something as strong as it and the opposite of it

Answer 1

Don't agree with you on that.  Have you got any examples?

Nature will may well return to a stable state but it might well not be the state it started from.  It's not as straightforward as there always being a counter-balancing effect to even things out.  

Are you , perhaps, thinking about the opportunistic nature of evolution that ensures gaps in the ecosphere get filled by whatever can best exploit the opportunity?

Answer 2

'Nature' is not self-aware and hence has no 'likes' or 'dislikes' .. and the suggestion that 'Nature makes' smacks of Religious Dogma (rather than scientific thinking) ..

.. however what is being suggested is a reasonable outcome of evolutionary pressure in some very restricted circumstances (for example, in a 'closed' system eg. Galapagos Islands, with limited availability of food resources it is quite possible that some predator would evolve to prey on the wide availability of another expanding species)

But the history of the earth teaches us otherwise .. in fact the evolution of our Planet has been a continuous sequence of 'wins' for each dominant species that comes along .. until some event wipes out them and most other life on the planet.

Indeed if it wasn't for the meteor 60 million years ago, the planet would still be ruled by the dinosaurs = they had the planet to themselves for upwards of 300 million years and nothing was 'made as strong' to balance them ..

With a bit of luck, mankind has at least another 200 million years before some external event knocks us off the top of the food chain :-)
