It's also the increase of carbon dioxide that causes problems.
It would be nice if there was something that could take carbon dioxide and, say, water, take energy in the form of sunlight, and convert the carbon dioxide and water to oxygen, sugars, starches, and oils. That would reduce the carbon dioxide level and increase the oxygen level.
Oh wait, plants do that! Something called photosynthesis.
However, if the calcification of the dome blocks the sun, photosynthesis would stop (the "photo" of "photosynthesis" being "light"; no light means no energy to drive photosynthesis).
When I saw the old people walking into the lake, I wondered if the Queen realized that decomposing bodies would produce carbon dioxide and something done to prevent the release of products of decomposition could conserve oxygen a bit longer.
