@jeffw1267 Driving folks into poverty is the single worst thing we can do for the environment, being able to think beyond this week's subsistence allows for NO consideration of anything beyond that.

@Arcadian_Gaming How much exactly is that? Higher value greenhouse crops often use 2000ppm CO2 to greatly enhance plant productivity, 4000 is even better but not worth the extra cost of the gas. The planet is greening from anthropogenic increased CO2 and it's a marginal safety net against the worst catastrophe possible on Earth--CO2 deficit that destroys all plant life and everything else along with it sans bacteria, not just hypothetical, we've come damn close to it in recent glacial maximums seeing as low as 180ppm when mass plant extinction is expected around 150ppm.
