What is the key difference in energy requirements separating microbial life from human civilization?

Answer

Microbial life is suited for slow, low-energy survival, while human civilization requires high energy throughput to maintain its structure.

Microbial life exhibits biological tenacity suitable for low-energy environments, whereas human civilization demands a massive and constant energy input to sustain complexity, technology, and density.
