so IIRC, plants are mostly made of carbon pulled from the air, this being especially true for fast growing plants with minimal root systems (there may be better examples than bamboo, but that one comes to mind). Also, we have plenty of big empty pits because of strip mining. So… why not just have bamboo / whatever farms whose sole purpose is filling those pits with “captured carbon” in the form of fast growing plants. Like yea some of it will rot, but if you pile it on fast enough it quickly becomes a hostile environment for most bacteria.

Buried plants would break down into methane, which is a fossil fuel *and* a greenhouse gas.
Methane can remain trapped in the earth’s crust, but trapping enough of it on purpose would be damn hard.
What would happen is the methane would bubble up and cause more warming. Then decay into carbon dioxide and water in the atmosphere – also greenhouse gasses.
Some genius would probably try to mine the stored methane to sell for cash before it gets out naturally anyway.
