Funny that you should mention that word "equilibrium" as that is the word that I was looking for when I discussed the issue with a friend here. Best that the dumb clerk that handles the files in my brain could come up with was "balance"

Your wordplay on mankind crushing the bubble is excellent, as there is no better way to describe the destruction. Frogs are nature's way of indicating fresh and drinkable water to us and I am afraid that they are on their last legs.

Mankind's "progress" is a killer in disguise, as there should be strict laws that ban developments in wetlands!
