        I was always under the impression that plants chemically convert CO2 and some other stuff to glucose (C6-H12-O6), right? In that case, the algae would still help, wouldnt they?

      Humans really are weird. Trying to replace a perfectly fine bio-machinery that developed over Thousands of years with their own steel junk. I dont see why anybody would prefer that gadget over a tree.

      Can you plant a tree capable of capturing the same amount of CO2 as those algae in that small a space? How about “refilling” the tree if it happens to die?

      Society doesn’t have to lock itself to a single solution for countless varied problems. If we’re talking about a long, empty walkway, or a park, then trees are a great solution. If we’re talking about a small space that must be kept free of obstructions, such as a bus stop, then a sack or box of phytoplankton is much better suited.

      What happens when we go too far and remove all CO2 from the atmosphere?

        Most plants would die because they rely on CO2 for photosynthesis.

        Many sea animals would die. Oceans absorb CO2 which forms carbonic acid (H2CO3) in water. Oceans are slightly alkaline due to dissolved salts (bicarbonate and carbonate) and the carbonic acid from the absorption helps to create a stable pH. Many sea animals are highly adapted to a specific pH and would die if the ocean got either too acidic or too alkaline, so they are pretty doomed in either case.

        Many humans would die because agriculture would collapse. Also breathing pure oxygen over a long period of time would be very bad because of oxygen toxicity. Yeah, pure oxygen is toxic for humans lol

        Land animals, I’m not so sure, but I assume most of them would die too.

        Your question isn’t entirely a hypothetical - this happened at the dawn of time, when photosynthetic life forms first evolved. First, it won’t ever happen again, no matter how good we get at scooping CO2 from the atmosphere. Second, the result is theoretically catastrophic for aerobic life forms, but it’s also a negative feedback loop, meaning it self corrects.
