domination of the biosphere
Continued destruction of Earth’s plant life places humankind in jeopardy, say researchers July 15, 2015 [image: Earth-space battery.

As this energy is dissipated by humans, it eventually radiates as heat toward the chemical equilibrium of deep space (anode). The battery is rapidly discharging without replenishment.
