#2ndLaw says all human activity generates heat

Fossil-fuels have allowed exponential human growth. We have to reverse the growth, not just stop using fossil-fuels.

Human activity generates heat. Energy exists in many forms; when humans move, heat, cool, build, or repair things, potential energy is changed into heat. This happens regardless of fuel source.

We have to move quickly to less activity and fewer humans.

Make buses fare-free, make cities car-free, people will urbanize and birth rates will fall. Driving around in wasteful autosprawl is a massive heat-generator.
