Yet creatures survive and reproduce, the fact that you can observe, analyze and even control.

I think you’re ignoring a bunch of dynamics by trying to model it with binary.

Prey population going down means a predator population also going down and a competitor population going up. It’s not an endgame, it’s just an “ear” of a very complex attractor, which with time only sharpens it ability to have as little escape points as possible.

1°C fluctuation by itself does nothing, because life usually has much wider tolerance due to long seasonal fluctuations. A global +-degree means there will be a tipping point somewhere which would bring a local drastic change. Locally life may suffer, but it counteracts with migration and preexisting diversity. It simply suffers everywhere, always. It’s a modus operandi. A little bit more is barely fatal.

So yes, survival is the default because life naturally specializes in it.
