They are usually talking about ant-colonies or other micro-ecologies. Tbf, there is likely alot of unaccounted CO2 production from those areas, but there is no way that it comes even close to the amount of CO2 industrial processes (particularly farming) create. It's just throwing chaff and is horseshit, but people want to rationalize it as not our fault, so they will grasp at even bullshit explanation.

They aren't 'universal' (other than the studio, yuk yuk) enough, as apocalyptic as they should be. Already seeing people just blaming California state government, and not connecting it to the awful smog and fires coming down from Canada, because memory is basically a month for most.

I'll see if I can actually find it, I only know about it second-hand myself.
