“CO₂ isn’t a pollutant” climate change deniers are missing the point, and hopefully this meme is simple enough for them to understand. I’d post it on Reddit too, but I’m trying to cut down on Reddit use.

If CO2 was thick enough at ground level, where plants grow, we’d be feeling it. We don’t have low O2 sensors, we have high CO2 sensors. Humans can happily suffocate and not notice as long as they can expel breath.
ironically eating meat is one of the biggest contributors of global warming
“Uh, water is essential to all life, so, like, I think you’re really overreacting about this flood.”
Sure, if you let the plants grow at a pace that matches your co2 output.
(We’re not doing that)
Aren’t crops (which of course are plants) actually growing faster due to increased co2. Due to this they’re also not able to develop as much nutrients and vitamins etc
My understanding is that nutrition has got more to do with selective breeding, soil microbial ecosystems, and depletion of plant micronutrients - we focus on macronutrients (N-P-K) in fertilizer.
But I think it does have an impact on plant growth. Fossil records suggest larger plants, and people who grow “tomatoes” indoors sometimes pipe in CO2 I think. Works well if you brew beer near your tent.
OK, this is from an ag class 35-years ago, but I’m sure it holds up: Yes, pumping CO2 at a plant gets significant gains.
The simple science is that plants do grow in heavier CO2 environments, sometimes very well. But they grow differently, which is a problem for food plants, because they don’t produce what we want from them as food unless we also add heavy nutrients and water. In a greenhouse environment, this can increase production. In the outside, it’s far more difficult to get good results.
So they aren’t wrong, they just don’t understand the bigger picture. Change one thing, other things change too, not always in the direction you want.
Also we are cutting down forests…
Pro tip: east the plants, then bury their babies in the resulting excrement. Profit!?
I think it was the Incans or Mayans that lived in a community of raised huts, shat from above into an area underneath & moved the village over when it started to stink. Then they’d plant seeds in the cleared fertile areas. Simple, efficient & brilliant… until it wasn’t anymore. Disease or Spaniards or a combination of the two, it ended up jungle again with little left to see other than mostly soil-science and foundational markings.
