Ask HN: Why does no one talk about greenhouse gas reclamation?

I understand why we always talk about reducing emissions but I never hear anyone talk about increasing reclamation of emissions. Maybe it isn't very feasible but it seems it would be possible to mass harvest a fast growing crop and then landfill it repeatedly to reduce the overall carbon in the air. For instance, wouldn't it be possible to take 1 million acres as a test project, cover it with bamboo, harvest the bamboo, cure it, and then place it all in a landfill and repeat? Wouldn't also be possible to do something similar with mass producing and harvesting sea algea?

There's also probably some process I do not know about where you could mass ingest and filter the air of all greenhouse gasses but since I haven't heard of anyone doing it, I'm guessing it's either unscalable or cost prohibitive.

I feel like there are many simple options for massively increasing the reclamation of emissions but I have never heard this addressed. I would love to know why or find any other sources discussing this topic.
