So you want to use plants to reduce CO₂ | Hacker News
TL;DR AI
2 min readKey summary
A Hacker News post about using plants to reduce CO2 sparked debate over how much plants really help.
Commenters noted that trees also respire, so their net impact on atmospheric CO2 is often overstated.
Others pointed out that the ocean is a far larger carbon sink than houseplants, trees, or mycorrhizal fungi.
The discussion also distinguished indoor air-quality benefits from the much larger problem of climate-scale carbon emissions.
