CO2 in the wild
Everytime I watch a nature show about a lake/river, I never see aquatic plants like our tanks. Occasionally I see the plants we keep in a marsh/swamp, but mostly floaters like water lettuce and water hyacinth.
Unless I see pics from information about invasive species, I do not see lush areas of alternanthera or hygrophila anywhere else.
I have read that Co2 is higher in some bodies of water because of groundwater, but other than that, most water bodies are relatively devoid of plant life.
