CO2 also helps plants grow. We should increase the atmospheres CO2 and urea production. More food for all!

  there's really more than enough CO2 in the atmosphere right now. The plants aren't struggling for it.

    Can you point to any research showing what the optimum level of co2 should be for plant growth?
    - beaconstudios 5y ago
      Can you? You're presumably the one arguing, in the face of the majority of climate scientists, that more CO2 is actually a good thing. For what it's worth, no gardener or farmer is having to pump CO2 into the air because their plants are dying.

        Your claim was “plants aren’t struggling for it” I’m asking if you can back up that claim. I guess not.

        Struggling as in dying. I've seen no evidence that plants are dying of lack of CO2. In my research into permaculture I've never seen any issues with plants lacking CO2 - primarily plants struggle for nitrogen, hence the use of fertiliser (or in the case of permaculture, other nitrogen fixing techniques like using bacteria or cycling legumes, or cool stuff like using aquaponics to recycle fish poo into fertiliser). Maybe they could grow even more successfully with some kind of CO2 biodome, I don't know - but my point was that lack of CO2 is not causing problems with plants growing, but it is causing problems with our biosphere slowly dying.

      It depends on the plant. Most plants grow faster at higher levels than the current 400ppm, so CO₂ supplementation in greenhouses is a thing, which you can read about if you like. Some plants grow fastest at levels around 1000ppm, and I think for others it's closer to 10'000 ppm, at which level it starts to become toxic for the humans. Of course if Earth's atmosphere were 10'000 ppm CO₂ we would see mass extinctions, major ocean acidification, etc.

  Water helps people live. We should all be constantly drinking water. We will be so much more alive. Every living moment: drinking water.

    Indeed. To be even more ridiculous: Being too cold kills people, therefore we should set ourselves on fire so we live forever. If someone wants to argue "more CO2 is good for plants", they really need to provide a number for what atmospheric concentration they think is optimal, and what the costs/benefits of reaching it are. Would increasing the concentration by 10% make food 10% cheaper, for example? What sort of effects on the Earth's climate are historically associated with CO2 levels that high?
    - hypertele-Xii 5y ago
      That's not ridiculous, that's literally ancient history ongoing. Those early human tribes that managed to keep a fire going forever are us, today. Still living theoretically forever, as long as the water and fire (and the amazing combination thereof, hot water) keep on going.
