There are two phases of terraforming:

- at first, a primitive civilization alters its environment
  without being aware of the consequences

- eventually, a more sophisticated approach is developed,
  which builds towards a desired outcome

For any given area (such as a city), the sum of methane emissions
 from natural or artificial processes, is the Methane Index.

* Methane is 20 times worse than CO2

ANAEROBIC MICROBES
- get energy by breaking long carbon chains into smaller pieces
- they can do this without oxygen, producing methane
- coal is one of the last steps of composting
    Proof is the methane canary.

AEROBIC MICROBES
- consume carbon using oxygen (higher energy)
- produces CO2, oxidizes equivalent of methane "burnt"

* in both cases the energy is lost to human activity
** then we spend to produce energy using oil, coal, ...

OXY
- methane can be recovered to produce energy, saving $ and ecology

Batteries floweth back to the Factory

CO2 is a used battery, which plants recharge.

What you want to do is pay it forward

In bio-capitalism, you generate your oxygen up front.

Oxygen will burn with iron or aluminum, hydrogen,
fossil or bio carbon, so the energy is really in the oxygen?

Biogas is a biofuel produced by the breakdown of biomass by bacteria
in the absence of oxygen.

To biogas is to capture the emissions (CH4) from a composting
solution deprived of oxygen, thus favoring the anaerobic bacteria.
