Do you eat meat?
I do, but not as much as many Americans. It is not necessary every meal. Do you?
Human civilization brought domestication of animals which led to their use in meat production on an industrial scale.
This is true, but before that I'm pretty sure agriculture was the main source of food. I could be wrong.
Agriculture was key to developing sedentary civilizations. Hunter gatherers predated agriculture, however.
That makes sense, we used to be more nomadic following the herd animals for sustenance. 
The Neolithic Revolution is when human culture transformed from hunter gathering to sedentary, agricultural societies that could sustain larger populations. Domestication of animals served to also increase the population of these societies.
Did this lead to a longer lifespan for human culture? I would think so. Having a steady supply of both crops and animals must have been beneficial.
I imagine it did. It led to an ecological footprint of a human population in some areas that exceeds the carrying capacity of that location.
Do you have an example? Do you  mean the ecological carrying capacity? I can tell that currently humans definitely have a negative effect on their environment.
